The 8 Best Water Filters in 2022

Deal Alert! Our favorite whole-house water filtration system from Aquasana is marked down for Cyber Monday.

The Spruce Eats Top Picks

The five-stage filtering system, ease of installation, and the fresh, clean taste of the water put the APEC ROES-50 Reverse Osmosis System at the top of our list. If you want a filter that attaches to the faucet, then the Pur PFM400H Faucet Water Filtration System is a perfect and attractive fit.

Water filters help improve the flavor of your water and protect you from impurities such as rust particles, bacteria, and lead. Sure, bottled water is easily available as a quick and (initially) cheap solution, but water filters are much more sustainable—and can save you money in the long run.

There are countless types of water filters available on the market, each differing in what they remove from your water. These include under-sink filters, faucet attachments, whole-house filtration systems, pitcher filters, and more. While there isn't a one-size-fits-all filter solution, we help narrow down the list of the best water filters based on your needs. Each item included in this roundup has either been certified by the NSF, a health and safety standards testing company, or tested and certified by an independent third party to meet NSF standards.

After extensive research and expert input, we rounded up the best water filters on the market.

Who else recommends it? Forbes also picked the APEC ROES-50 Reverse Osmosis System.

What do buyers say? 85% of 6,100+ Amazon reviewers rated this product 5 stars.

A highly efficient system and also an attractive option, this reverse osmosis filtration system is designed to be placed under the sink; it can, however, also be placed in a basement or attached garage with the water routed to the sink with the included faucet. Along with the typical lead and other heavy metals, bacteria, and chlorine, this removes as many as 1,000 different unwanted contaminants from water.

This system uses five separate stages of filtration to remove 99 percent of contaminants. It has a sediment filter, two stages of carbon filters, a reverse osmosis filter, and a coconut fiber filter. Filters need to be changed at different intervals; The first three last six to 12 months, while the two stages can last two to four years.

Installation is designed to be a DIY project, but specialized tools may be required to install the faucet if there isn’t already a hole drilled into the sink or counter. Still, most reviewers like that the instructions are very clear and that the system is relatively quick and easy to install.

What Our Experts Say

"Counterfeits are a problem for a number of reasons. First and foremost, they likely won’t remove the contaminants you expect them to and could therefore pose a health risk. Also, if they are made with substandard materials that leach they could actually make your water worse. The number one indicator of a counterfeit is price. Counterfeit filters and replacement cartridges usually cost significantly less than authentic certified products." — Rick Andrew, Director of NSF International's Global Business Development

When an under-sink filter is too much trouble but pitchers aren’t sufficient, a faucet attachment can be the perfect fit. Many customers who rated this filter highly did so because of how simple it is to install: It mounts easily to the existing faucet without any tools. Plus, it removes a host of common contaminants like lead and other heavy metals, chlorine, pesticides, and more. The internal filter is easy to change—which is necessary every two to three months based on average water use. A sensor checks the filter and indicates when it’s time for a change, so there’s no need to track time or usage.

Since there are plenty of times when filtered water isn’t required, this makes it simple to switch filtering on and off—so drinking water is clean, and cold brew coffee tastes right, but the dishes can be rinsed in unfiltered water. This attachment includes three different adapters to fit common faucets, but it won’t work with pull-down or handheld faucets.

Most water filtration systems are designed for kitchen use only, but if the local water supply is so off-putting that brushing your teeth makes your mouth feel dirtier than before, a whole-house filtration system may be the best option. Not only will the water from all the faucets be clean and drinkable, but the water for your shower or tub will also be filtered.

This system filters and conditions the water, so it removes heavy metals, chlorine, pesticides, and contaminants. Several customers who typically deal with hard city water treated with heavy chlorine claim that the odor was completely removed and their water is softened adequately. A less expensive option that filters but doesn’t condition is also available, as are several other filtering options, so there’s something for every need. The system itself is rated to last for 10 years or 1 million gallons, but filters need to be changed about every three months.

Note that while all of Aquasana's filtering systems are NSF-certified to remove PFOA and PFOS, the whole-house system in its entirety is not certified because the company cannot guarantee that contaminants are not in the house's pipes and being picked up after going through the system.

Good to Know

The CDC has a wealth of information to help you decide which type of water filter is best for your home. One word of caution about whole-house systems: According to the CDC, "filtering that removes chlorine might increase the growth of germs in all the pipes in your house."

Great for small spaces, this pitcher holds 7 cups, so it won’t take up a lot of space in the refrigerator or on the counter. It’s great for filtering drinking water for singles or small families and is small enough to bring to the office or on trips. While it might take several batches to fill a large pot for making stock, this will work well for small cooking tasks.

This filter removes chromium, lead, and other heavy metals, along with all solids. Several reviewers commented that the filtered water tastes just as good, if not better than bottled water. The filter also includes a water quality meter, so users can test their water before and after filtering. How often you replace the filter depends on the contaminant level of your water, but most places within the United States fall within the 25- to 40-gallon range.

Let’s face it: Most water filter pitchers are built for function, but they don’t look great for serving. The last thing a host wants is for guests to be wondering how bad the water really is, so this pitcher hides the filter from view with an attractive design element. Since it filters as it pours, you just fill it and bring it to the table to fill water glasses. Most customers are happy with the flavor of the filtered water; however, some note that it pours more slowly the less water there is in the pitcher.

This holds 12 cups and is designed to fit the fridge, so it’s ready to dispense chilled water when you want it. It has an electronic filter change reminder, so you don’t have to chart time or usage. It’s made from BPA-free plastic, and the filters are recyclable through TerraCycle.

This countertop dispenser holds 18 cups of water, which eliminates the need to filter batch after batch for larger families or cooking projects. It’s certified to remove 99 percent of lead, along with 22 other contaminants, and can filter up to 40 gallons of water before the filter needs to be changed.  

The proprietary filter cap ensures that only filtered water moves from the top reservoir to the bottom, so unfiltered water won’t mix in. This is designed to fit in the sink for convenient filling and is well balanced, so it’s easy to move to the counter where it will be used. Several customers say the dispenser was very easy to set up and operate, though some note that it takes some time to filter water.

There may be some instances when you only need to filter one serving of water, like at work or on vacation. In this case, your best option may be a water filter water bottle, such as the Brita Hard Sided Water Bottle.

This handy 26-ounce water bottle is made from BPA-free hard plastic, and it has a built-in carbon filter that will remove impurities from up to 40 gallons of tap water. The water bottle is dishwasher-safe and fits in most car cup holders. The manufacturer recommends changing the filter every two months, and reviewers say it's the perfect water bottle to take on vacation to areas where you might not have clean tap water.

Price at time of publish: $17

Type: Water bottle | Certified By: WQA | Contaminants Filtered: Chlorine taste and odor

Good to Know

Some self-filtering water bottles are only effective for treated municipal water, whereas others can handle water with a greater contaminant load. For your safety, before you buy a filtered water bottle for traveling to places without easily-accessible drinking water, check the specifications to make sure it can handle more than treated city water.

This water filter removes chlorine and heavy metals but leaves behind the minerals that help water taste good, so it’s perfect for a refreshing drink or for making tea, lemonade, or cocktails. Unlike under-sink filters that filter all the water used—including water for washing dishes—this comes with a dedicated faucet so you can have filtered water when you want it, while not wasting filtered water for washing and rinsing.

This can produce up to .75 gallons of filtered water per minute, so there’s no waiting when filling a pitcher. Even users with no experience with plumbing praised the ease of installation, and they also praised the easy filter replacement. According to the manufacturer, changing the filter takes just 3 seconds.

The filter is good for 8,000 gallons of water before it needs to be replaced, but for people who use a lot of water, a 16,000-gallon model is also available. For renters or people who don’t want to drill a hole for the dedicated faucet, there are models that connect to the faucet to filter all of the water.

Price at time of publish: $61

Type: Under the sink | Certified By: WQA | Contaminants Filtered: Chlorine, sediment, rust, and other heavy metals

Good to Know

The CDC notes that no filter can eliminate all contaminants, and many are specialized. To know what contaminants need to be removed, certified labs can test water from private wells or cisterns. For city water consumers, a Consumer Confidence Report is sent annually with the water bill.

Final Verdict

The APEC Top Tier 5-Stage Ultra Safe Reverse Osmosis Drinking Water Filter System earns our top spot because of its five-stage filtering system and simple installation. Reviewers praise how clean and smooth the resulting water tastes. If neither under-sink filters nor pitchers are options, try the Pur PFM400H Faucet Water Filtration System; it's attractive, effective, and you don't need tools to install it.

What to Look for When Buying a Water Filter

By Marshall Bright

Purpose

Water filters can remove contaminants like heavy metals and man-made chemicals from your water. If you are on well water, have old pipes, or live in an area with unsafe drinking water, you may need a water filter to remove contaminants like lead or actual particles like sand.

If you are on city water, you can look at the annual water reports to see what kinds of contaminants are in that water. Even if your municipal water is safe, you may have old pipes that could be leaching contaminants into your water. Adding a water filter can help remove those impurities. Filters certified to remove chlorine, for example, can also encourage hydration by making water more enjoyable to drink.

Independent Certifications 

Because effective filtration is so important (and because it’s so hard to actually be able to tell if it’s working), certification is one of the only ways you can actually be sure your water filter is removing the contaminants its packaging claims. The NSF is one certifying body—other certifications to look for are the American National Standards Institute (ANSI) and the Water Quality Association (WQA). There is no one-size-fits-all certification, so it’s important to know what you want removed from your water. For example, the NSF offers certification for removing a certain amount of chlorine, and a separate one for removing lead. The more certifications a filter has, the more contaminants it can remove. 

Andrew cautions that you just need to make sure your filter is actually certified. Marketing jargon to look out for includes “filters to NSF standards,” which does not mean it has been independently tested. An earlier version of our list included several water filters that were removed based on similar language that made it unclear whether they were independently tested.

Capacity

You will want to consider your household’s water consumption when purchasing a filter. A smaller pitcher may be fine for a dorm or apartment, but for larger households or using filtered water for cooking, faucet or under-sink filters may make more sense. Refilling a pitcher doesn’t take a huge amount of time, but if you need to do it several times a day, it can be a pain.

Replacement Filters

Filter cost is another thing to consider. A water filtration system is only as good as its filters, so be sure to factor in their price and availability, as well as how often they need to be replaced.

Cost

Water filtration systems can cost up to thousands of dollars, while smaller pitchers can go for around $20. You can get an affordable water filter for personal use without spending much, but make sure to look for certifications. Also, consider the cost of the water filter and how often it will have to be replaced when deciding what you want to spend.  

Types of Water Filters

When we think of water filters, a pitcher is the first thing that comes to mind, but filters can be used at almost every point of water's journey through your home. 

Whole-Home Systems 

Whole-home systems filter all the water coming into your home. The most common kind, says Rick Andrew of NSF International, "is a water softener that will help remove minerals and 'soften' your water." Since hard water is bad for pipes and water fixtures, a whole-house filtration system makes the most sense. Because this type of system filters water for the whole house, it's often expensive and time-intensive to set up. 

There are two reasons to get a water filtration system, explains Andrew. For drinking water in the United States, it's more likely that you’ll want a filter to improve taste or remove hard minerals and protect your pipes. Hard water (i.e., water with high mineral content) can damage pipes and water fixtures with buildup.

Under-Sink 

If you are filtering for contaminants or taste in your drinking water, a point-of-use filter is also an option. These can be filters that attach to the sink or under the sink where you get drinking water. Andrew emphasizes that whole-house filtration, unless you are on a well, is generally only for softening water, and that these point-of-use systems are sufficient if you’re filtering out contaminants. Under-sink filters are often easier to install than whole-home systems, but are more expensive than faucet attachments or pitchers. 

Faucet Attachments 

Like under-sink filters, faucet attachments offer instant access to filtered water at a place where you would be getting drinking water, such as the kitchen sink. These filters can typically be attached to most standard sinks, though they won't work with more unique sink setups, like a pull-down faucet with a spray nozzle. A faucet attachment will typically allow you to filter only the water you want to drink and let unfiltered water come through for things like washing dishes. If you are only filtering to improve taste, this should be sufficient. This type of system also puts less pressure on the filter by only filtering the water you need. 

Pitchers

Pitchers don’t offer the convenience of a sink filter because they need to be refilled, but Andrew says "some people prefer pitchers because they allow you to chill filtered water, which can make it more enjoyable to drink." It’s also the easiest to set up. Furthermore, if you are only filtering water for taste, you may find a faucet filter to be bulky and unnecessary while you do things like wash hands or dishes at the sink. Again, this comes down to preference, and both faucet attachments and pitchers are capable of filtering out contaminants. 

Countertop 

Countertop water filtration systems work similarly to faucet filters by diverting water from the sink into a filtration system with its own tap. Other countertop filtration systems need to be filled, acting like water coolers, and these can be bulkier than pitchers but require less frequent refilling. They do offer the advantage of allowing you to place filtered water anywhere in your home, away from a water source. 

Bottles

Special water bottles can filter water as you fill the bottle or as you drink, and they can be certified by the NSF and ANSI. Water bottles can be a great option if you want to drink filtered water on the go, and they're a great alternative to buying bottled water. However, certain filter bottles are only designed to remove contaminants from treated municipal water, so if you want a water filter for hiking or traveling in places without clean drinking water, you’ll need to be extra sure that the filtration system you're buying can remove bacteria and other organisms. 

While filters of all types can do a great job of removing contaminants, Andrew says, "no filter can actually remove all contaminants." Any filter that claims it can remove all or 100 percent of contaminants is misrepresenting itself, and no certifying body would verify those claims. "The technology just doesn’t exist," Andrew says. 

Brands

Brita

Nowadays, the term “Brita pitcher” has basically come to mean a filtered water pitcher. Brita’s filters all come with NSF certifications, and its pitchers are popular for their ease of use—drop a filter into the pitcher, and you’re good to go. Brita also offers a wide array of pitchers and filtration systems, including faucet filters and water bottles. Brita does not offer under-sink or whole-home filtration systems, however, and not all Brita filters are created equal. Depending on what you want filtered out of the water, make sure to check for those certifications. 

Pur 

Pur and Brita offer very similar products: basic filters that remove impurities for taste, as well as mercury and other contaminants, as well as more expensive filters that can also remove lead and an even higher percentage of contaminants. Pur does offer the most certifications in its basic and more expensive filter.  

APEC

APEC offers a whole-house filtration system in addition to countertop filtration systems. The company’s whole-home systems are designed to remove things like odor and chlorine, as well as minerals that can cause scaling on appliances. 

Maintenance 

Water filter systems, no matter the size or type, are not a one-and-done purchase. Filters don’t last forever; they'll eventually stop effectively filtering water. "This can have two effects," Andrew says. For starters, the water can start to flow more slowly through the filter itself. More seriously, the filter can also stop effectively filtering water, letting the contaminants stay in the water. Filters all come with a lifespan, from a few months to a few years. NSF certifications test to ensure that the filter can continue to remove contaminants for as long as its listed lifespan and even allow for a little bit of time on the end. 

“But, at some point, it's just not going to work anymore,” Andrew says. Replacing your water filter per manufacturer instructions is just as important as purchasing the right filtration system in the first place. 

Accessories 

As brands try to set themselves apart in the filtration space, different accessories and add-ons have popped up such as Bluetooth capabilities and sensors to monitor filter effectiveness. While these can be appealing bells and whistles, they are not necessary; if you follow manufacturer guidelines on replacing filters, for example, the sensor is unnecessary. Ultimately, what matters is if the filter itself is capable of removing the impurities you want removed. 

FAQs

Which water filters remove the most contaminants?

While there are a variety of water filtration systems, no one type is inherently better (or worse) at filtering out contaminants. The same types of filters can remove different contaminants depending on how it was manufactured and certified. This is why experts recommend knowing what kinds of contaminants you want to be removed, rather than simply looking for a filter that removes a lot of contaminants. If you are unsure of what is in your local water, you can get a water report. 

Do water filters remove bacteria? 

"NSF certifies filters that remove bacteria under a standard called P231," says Andrew, but those tend to be designed for activities like camping, when you may need to drink water from a stream. If you have specific concerns about bacteria in your drinking water, be sure to buy a filtration system certified specifically to remove bacteria. When in doubt, you can boil your filtered or unfiltered water as an added safety precaution against bacteria.

Can you filter any type of water? 

In short, absolutely. Water filters can be used for city and well water and on both soft and hard (high mineral level) water. Just be aware of what you are hoping to remove; a whole-house system specifically designed to remove minerals from hard water, for example, won’t work the same as a pitcher that removes chlorine for flavor. 

Do water filters remove fluoride? 

Yes, certain types do. If you have a preference, be sure to check your filter’s certification. 

Do water filters remove PFAS?


There are water filters that remove polyfluoroalkyl substances (PFAS) very effectively, and filters that only have partial efficacy in removing them. If this is an area of concern for you, make sure you pick a filter that specifies removing PFAS.

How long do water filters last? 

Water filtration systems are only as good as the filters within them. Nearly all are designed to be replaced, and all certifications are done with the life of the filter in mind. So if your filter needs to be replaced every six months, NSF will test each filter to ensure a six-month lifespan. If filters are replaced regularly, the filtration system itself can last for years.

How do I choose a water filter? 

All water filters work in the same way: tap water passes through a filter that removes contaminants. There are different styles of filter, though.

Under-counter water filters are designed to fit into a cabinet and usually come with a new faucet. These give you clean, filtered water at the same flow rate as your regular faucet. Although harder to install, you get the benefit of a single faucet to use for everything, and you can quickly use filtered water everywhere, from cooking to filling a water bottle to take away.

Countertop water filters work in a similar way to under counter, but they’re usually connected to your faucet. You get the same advantages as with an under-counter model, but these models are easier to install. Having a bulky device on your kitchen counter is the main downside.

Pitcher water filters have everything built into a jug. You fill up the top reservoir with tap water, and it’s filtered through to the bottom as clean water. These are quick and easy to use, and you can store a jug of filtered water ready for use. The downsides are that you need a jug double the size (half for tap; half for filtered), and there’s a short wait for filtered water every time you fill up.

Bottle water filters are designed for on-the-go use. They’re handy if you’re on the move and want to refill your water from anywhere.

What does a water filter remove?

Each water filter system is different, so you need to check carefully what each one offers and its particular features. It’s worth pointing out that bacteria are generally not removed by most water filters.

Water filters will generally all remove chlorine and prove to be roughly 90 per cent effective. Other contaminants include volatile organic compounds (harmful chemicals), heavy metals, and sediments. 

How often should I change the filter itself?

Filters are rated: by the gallon, and most water filter systems will track how much of the filter is used. Once it’s time to replace the filter, you’ll get a warning. Cheaper systems that don’t track actual usage will tell you how long each filter will last.

Typically, you should replace filters promptly, as they’ll stop working effectively, and you may as well have non-filtered water.

Wash water filter: ratings and tests . What is the reason for these deviations? It seems that nothing specifically bothers, it doesn’t hurt, but still ... The answer may lie on the surface - the point is in the water that we drink every day, with which I wash the dishes that we use for cooking.

Experts advise you to use filters - using them will allow you to be sure of the purity of the water. The most versatile solution can be a water filter installed under the kitchen sink. What are its advantages and which model to prefer? Let's figure this out.

What are tap water filters? One is a faucet attachment. They are easy to install and operate, but do not perform as well as other cleaning systems. Some housewives, among other things, believe that the nozzle on the tap is not very aesthetically pleasing.

As far as jug filters are concerned, there are no such problems with them. However, the water purified in such filters can only be used for cooking and drinking, but it will be technically impossible to wash the dishes with it. And this is very important, especially for families with children.

The best solution for water purification is the sink filter. It is convenient, inconspicuous and, most importantly, it has a great resource. Such a cleaning system is a structure connected to the water supply by hoses. The standard kit includes three (maybe more) plastic, interconnected flasks and a faucet for purified water.

When choosing a filter, it is important to determine the requirements for water treatment. It can be multi-stage microfiltration treatment . In this case, the system combines sorption cartridges for different purposes. At the first stage, water is mechanically purified from foreign particles (sand, rust) using a polypropylene mesh, otherwise called a mud filter. At the second stage — removal of pesticides, chlorine and its compounds, oil products. Typically, such microfiltration is carried out through the use of a sorption carbon filter that screens out contaminants with a size of 1.0 microns (10-6m). At the third stage, the water is softened by ion exchange and freed from heavy metals. Such cartridges are not regenerated and require timely replacement, otherwise, instead of purifying water, they will act as a source of pollution.

Reverse osmosis water treatment is no less popular. First, there is a preliminary purification of the liquid from mechanical impurities. Then water under pressure passes through a special membrane that does not allow harmful chemical and biological compounds to pass through, the size of the molecules of which exceeds the size of the water molecule (about 10-10m) - these are hardness salts, heavy metal ions, organic pollution. The method is recommended for low quality tap water, but requires a mandatory pre-filter that protects the membrane from damage by large particles of impurities.

Important!

The reverse osmosis membrane does not retain chlorine, iodine, fluorine and some other chemical elements poorly. In addition, chlorine corrodes the membrane material itself, nullifying all results. For this reason, constant pre-filtration (sorption) of chlorine through carbon cartridges is required, which must always be fresh.

The process of such filtration is quite lengthy, therefore, for the convenience of supplying the user, water is pre-accumulated in a special tank, from which it is supplied through a separate tap. As for the filtered substances, they are washed off the membrane surface with a water stream [1] and sent to the sewer (this accounts for up to 75% of the initial volume of water). As a result, we get pure water, which contains almost no impurities, including mineral salts (98% cleaning). Cartridges are non-refundable.

In addition, there is an ultrafiltration system , , which uses polymeric multichannel membranes with a pore size of about 0.01 µm (10-6m). They purify water from bacteria and viruses, the size of which exceeds the size of the pores of the membrane. Colloidal contaminants are completely removed by ultrafiltration.

Ultrafiltration membranes are placed in modules and mounted in the units themselves, consisting of a raw water supply pump, a sump, a rack with ultrafiltration modules and a filtrate/backwash tank. In some cases, water can be supplied directly to the consumer, bypassing the tank, since the filtration process is not as slow as with reverse osmosis. To wash away the layer of contamination from the membrane, a backwash is periodically carried out. Sometimes chemicals are added to the water supply line to improve its efficiency.

All of the above applies to nanofiltration , which is considered as a type of ultrafiltration, but with the use of membranes having an even smaller diameter - 0.0001 microns (10-9m).

Special attention should be paid to the patented polymembrane technology of water treatment, which bears the eloquent name "Water Doctor" (Doctor Water). It is based on the use of various membranes with predetermined properties that accurately reproduce the work of lipid-cell membranes of a living cell. Filtration systems of this type use the so-called track membranes developed under the guidance of Academician G. N. Flerov. All elements of the devices are interconnected and do not work individually. This latest development allows you to get water purified from all possible contaminants by 100%.

Filtration occurs not only due to different membrane permeability and selectivity, but also due to different polarization. At the stage of fine purification, an electrostatic field is created between two differently charged membranes, which is capable of retaining particles that are much smaller in size than the pores of the track membrane itself. Additionally, the electromagnetic field structures drinking water, bringing its properties closer to the characteristics of the internal environment of the human body. At this stage, even micro-quantities of harmful impurities are completely removed, all microorganisms and their fragments are eliminated. At the same time, water retains the natural content of all macroelements, electrolytes and other nutrients necessary for a person, acquiring physico-chemical parameters similar to those of a liquid in a living cell.

This is interesting!

GN Flerov's track membrane was originally used in medicine to purify blood and its preparations (for plasmapheresis). This device, from the point of view of the science of filtration, is ideal for cleaning liquids and gases from microimpurities (dust, suspensions, bacteria, etc.) [2] .

"Water Doctor" filtration systems consist of several modules (there can be up to six or seven pieces depending on the condition of the source water), in which cartridge blocks of various degrees of purification are installed: from a prefilter to filters on track membranes. Some cartridges are subject to regeneration. Also, the system may include a hydraulic accumulator, which ensures an uninterrupted supply of drinking water. The VD-TM205 Lux series has a dual-circuit water supply - separately for washing dishes / cooking and separately for drinking needs.

It’s not beer that kills people…

You can try to determine the quality of tap water yourself by paying attention to some signs that are characteristic of low-quality water:

  • putrid taste of water is a sign of the presence of hydrogen sulfide and organic substances in it;
  • astringent taste indicates an excess of iron;
  • the gray tint of clothes after washing indicates the presence of manganese and heavy metals in the water.

    • But all of the above is just the tip of the iceberg: 80% of fine chemicals dissolved in water are colorless and odorless. For this reason, household "experts" are reckless in assessing water quality by the presence of calcium, since it is visible.

    This is interesting!

    When boiled, water-soluble calcium - an extremely useful and important macronutrient and electrolyte for health - turns into an insoluble form, precipitating a white precipitate. But even in this form, it can still be useful. In modern SanPiN, where the content of hundreds of chemicals is normalized, calcium is completely absent, since it is not a toxic substance.

    When choosing a filter, take into account the local characteristics of the water composition. For example, in those regions where wells are the source of water supply, the content of hardness salts, iron, and sometimes fluorine and manganese is increased in the water.

    Important!

    For long-term and stable operation of reverse osmosis and nanofiltration plants, it is necessary that the water entering the membrane meets the regulatory requirements for a whole range of indicators, which are usually given in the instructions for the device.

    In order to know exactly the composition of water, it is advisable to take a sample for laboratory analysis before buying a filter. The result of the study will allow you to choose the treatment system that is suitable for the treatment of your particular water. The choice of manufacturer is also important. Let's talk about this in more detail.

    Rating of water purification filters for washing

    Today, a variety of systems for water purification at home are widely represented on the market - both from Russian and foreign manufacturers. About a dozen well-known companies confidently compete with each other. Consider the products of the most popular of them.

    "Water Doctor" (manufacturer - EcoMembrany LLC)

    water treatment. Today the company has its own research base. "EcoMembranes" is a developer and manufacturer of water purifiers-correctors and integrated water treatment systems based on the innovative technology "Water Doctor" (Doctor Water). A feature of the filters operating on the technology of "Water Doctor" is their ability to turn water from almost any source into drinking water of the highest quality without the use of bacteriostatic additives.

    All washable filters of the EcoMembranes luxury series have 15 stages of water filtration and correction, including the stage of treatment with track membranes. Water purifiers-correctors "Water Doctor" allow you to rid the source water of most known pollutants, including active chlorine, organic and organochlorine compounds, toxic metals, and other substances harmful to health, as well as to structure and bioactivate drinking water. The drinking circuit guarantees 100% water purification from common (OKB) and thermotolerant coliform bacteria (TCB), as well as from pathogenic bacterial agents: pathogens of cholera, salmonellosis, plague and their fragments. Unpleasant odors are eliminated, the taste of water is improved. The resulting drinking water has a molecular structure and properties that are maximally adapted to the liquid media of the human body.

    The macroelement, microelement and electrolyte composition, necessary for the normal functioning of a living organism, stored in drinking water allows protecting the cells of a living organism from destruction and improving the functioning of all organs and systems.

    Buyers note that water purifiers-correctors from EcoMembrany LLC are easily integrated into the water supply system, maintain water pressure and do not require high operating pressure in the network. At the same time, each of the devices perfectly purifies water from a water supply system, a well or a well, preserving all microelements useful for health in its composition. It is noted that high quality indicators of water purification are maintained throughout the entire service life of the devices.

    Barrier

    This company has been producing products since 1993. At the moment, the company has its own research laboratory and full-cycle production. Barrier products are popular in the post-Soviet space and abroad. A special place in the assortment is occupied by filters for washing: customers can choose the system most suitable for water treatment in their apartment or house:

    Customers note the attractive appearance of all designs, the simplicity and convenience of changing cartridges, as well as the pleasant taste of filtered water.

    Important!

    It must be remembered that the performance of a reverse osmosis system directly depends on the pressure in the water supply. If it is less than 3 atm, then it is necessary to use a booster pump complete with a high pressure sensor (the sensor is required so that the pump works only when the storage tank is being filled). If there is a risk that the pressure in the system will rise to values ​​exceeding the normative values, a pressure relief valve should be prudently installed upstream of the pump.

    Geyser

    Another Russian company that started water treatment in 1986. The company's products are well known in different regions of Russia, in countries near and far abroad.

    The Geyser Ultra Bio and Geyser Eco models are also in demand. Those who have already used Geyser filters note the quality of water purification, but also the complexity of installation, which is not easy to do on their own.

    Aquaphor

    92 year. The company manufactures all types of water filters. In the line of filters for washing, it is worth noting the following models:

    In order to remove bacteria and soften water, you can use the Aquaphor DWM-41, Aquaphor DWM-101S Morion models.

    Ease of installation and acceptable filtration rate of Aquaphor equipment allow us to classify this manufacturer as a worthy one.

    Prio

    Russian company founded in 1996. Since 2006, the company has become a member of the International Water Quality Association. Among the wide range of products, a special place is occupied by filters for washing.

    Also noteworthy is the multi-stage filter for sink Expert M330, with four filter elements and five stages of water purification.

    Users of Prio filters cite the ease and convenience of installation as an added benefit. The downside is the "demanding" of these filters to the quality of the water supplied. In this regard, the manufacturer recommends: if the source water is characterized by high turbidity and contains a large amount of suspended impurities (silt, sand, rust, etc.), then these systems should be installed after the main mechanical filter with a filtration fineness of at least five microns. The mineralizer is not included in the kit, which also refers to the disadvantages of the system.

    Atoll

    This brand appeared on the Russian market in 1994, when American water purification systems began to be sold by order of Rusfilter. Today it is a large international corporation with American roots.

    Also in a small kitchen it will be possible to place an Atoll A-550 box STD (Sailboat) reverse osmosis system. Buyers note the high quality of Atoll sink filters, as well as the ease of installation of the structure. Additionally, it is advised to purchase a mineralizer.

    Important!

    In order to eliminate microbiological contamination of the water entering the pre-filters that do not contain bacteriostatic additives and protect them from fouling, manufacturers of reverse osmosis filters (including Atoll) recommend that a UV lamp be pre-installed in the system, which is purchased separately.

    Bluefilters

    German company with offices in 12 countries. High quality, reliability and compliance with all modern requirements - this is the general characteristic of the products of this brand. Especially popular in Russia are filters with a reverse osmosis system.

    Buyers of filters note the pleasant taste of water, but, in their opinion, there is also a negative point - the price is too high, which is several times higher than the cost of similar domestic devices.

    Thus, there are various models on the market for sink filters. Both domestic and foreign manufacturers successfully compete here. But you should focus not only on the brand, but also on the characteristics of the composition of the water in your home.
