The 8 Best Water Filters of 2022

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

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 in a Water Filter

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.

We updated this article in April 2022 to add more information about each featured product, based on extensive testing done by the Good Housekeeping Institute. Our original top-rated picks — selected by the Kitchen Appliances; Home Improvement and Outdoor; and Health, Beauty and Sustainability Labs — remain the same, though we swapped out discontinued products for new winners including Brita, Aquatru, Sonaki, Culligan, Aquasana and Larq.

We all know how important it is to drink enough water. While many people have water dispensers in their refrigerators, some still rely on good ol' tap water. If that’s the case, you may want to add a water filter to your kitchen tools and gadgets to help filter out harmful contaminants like chlorine, lead, pesticides and more, which can affect taste, quality and in some cases clarity of the water.

The Good Housekeeping Institute is a champion of safety and sustainability, which is why water quality and water filters have been important to us for decades. Our Kitchen Appliances; Health, Beauty and Sustainability; and Home Improvement and Outdoor Labs regularly team up to evaluate the efficacy of popular water filters to ensure they properly filter harmful contaminants. To find the best water filters — including whole-house water filters, under-the-sink water filters, water filter pitchers, water filter bottles and even water filters for your shower — our experts narrowed it to the top-selling options, then collected hundreds of data points and evaluated contaminant removal certifications. We also took into account how easy it was to set up the filter, how quickly it filtered, how heavy it was when filled (if applicable), how easy it was to clean and more.

How we test water filters

In order to find the best water filters, we search the filter market and use our categorical expertise to narrow it down to the most promising products.

We take into account how easy it is to set up and, if applicable, how easy it is to pour and how much water it holds. We also read each instruction manual for clarity and look at whether pitcher models are dishwasher safe. As applicable, we test performance factors like how quickly it filters a cup of water and measure how much water the tap water reservoir can hold.

We also verify contaminant removal claims via third-party data. We review how long each filter lasts and the yearly cost to replace filters if changing filters at the recommended time frame.

What to look for when shopping for the best water filter

✔️ Type and capacity: For pitchers, water bottles and other dispensers that hold water after it’s filtered, you’ll want to keep in mind size versus weight. Larger containers are ideal for refilling less often, but they will often be heavier and may take up more space in the fridge or your backpack. A countertop model saves space in the refrigerator and often holds more water, but it does require room on the counter.

With under-the-sink water filters, faucet filters, in-line shower filters and whole-house filters, there’s no need to worry about size or capacity as these instantaneously filter water as it flows through.

✔️Method: Most water filters use either a carbon filter or a reverse osmosis water filter, which can also include a carbon filter. The primary difference is that most reverse osmosis water filters use multiple filter types to remove more contaminants than carbon filters alone. However, some reverse osmosis systems also remove minerals that some may prefer to leave in. With both reverse osmosis and carbon filters, the contaminants they remove can vary widely, so it's best to check what the model actually filters so it suits your needs.

✔️ Filter replacement frequency: Check how often you have to replace the filter. If you dread changing the filter or simply forget, you may want to look for a long-lasting filter. Also, if you buy filters for the shower, water pitcher and sink, you’ll have to remember to change those separately, so it might be smart to consider a whole-house filter that requires only one filter replacement for the entire home.

No matter which water filter you opt for, it’s no good if you don’t change the filter as recommended. Birnur Aral, Ph.D., says, “The performance of the water filter depends on the quality of the water source and whether or not the filters are replaced regularly.” Some models come with indicators, but it a model doesn’t include one, a slower flow rate or different-colored water are signs that you need to change the filter.

✔️ Price: Consider both the upfront price of the water filter device and the filter refill costs. A water filter could cost more initially, but the price and frequency of the filter refills may save money over the long term. But that’s not always the case, so be sure to calculate the yearly cost of replacements based on the recommended schedule for changing.

Do you really need a water filter?

Access to safe drinking water is an issue across the globe, and it affects communities in the United States. If you’re not sure about your water quality, the Environmental Working Group (EWG) just updated its Tap Water Database in 2021. It’s free and easy to search, and it has information for all states. Enter your zip code or search your state to find details on your drinking water quality based on EWG standards (which are stricter than those of the government). If your tap water does exceed EWG health guidelines, it may be a good idea to consider buying a water filter.

Opting for bottled water is a short-term solution to potentially unsafe drinking water, but it creates a much larger problem with serious long-term implications with regards to pollution. Americans throw away a whopping 30 million tons of plastic a year, only 8% of which is recycled. The majority ends up in landfills because there are many different regulations about what can be recycled. Your best bet is to get a water filter and a cute reusable water bottle — some even have filters built-in!

Rating of the best water purification systems for home and apartment

What contaminants are most commonly found in well and other source water?

The best water purification system in the world will not work effectively if you skip the step of checking samples from the source. This procedure is professionally performed in a specialized laboratory, which will prepare an official report with real indicators for all control positions.

Samples are taken after draining the liquid under medium pressure for 10-15 minutes to exclude contamination from impurities from the pipeline. Use a clean container for storage. The analysis is performed no later than 48 hours after sampling.

Open water bodies are heavily polluted, so they are rarely used. This choice implies an overly complex processing technology. The best water purification system will only work correctly if the filter media is changed frequently, which will greatly increase the associated costs.

Water from a well, well and city water supply has a huge amount of harmful inclusions that need to be filtered

Connection to a well is well suited for a private house. This solution provides effective natural filtration, since the sampling point is located at a great depth. A characteristic disadvantage is the contamination of water with impurities washed out from rocks. Therefore, stages of reducing the level of hardness and iron removal are added to the water treatment scheme. The first one prevents the formation of scale from magnesium and calcium salts. The second - removes the dissolved ferrous iron, which is converted into rust.

For the house, water can be drawn from a well. In this case, it will be necessary to remove:

suspension, sand, other mechanical fractions;

organic;

chemical compounds;

bacteria, other micro-organisms.

Finding the best water treatment system for your apartment is easier. The supplying organization is obliged to carry out processing in accordance with the current SanPiN standards. However, in this case, homeowners solve individual problems on their own. Pollution from heavily worn main networks and chlorine, which is used to disinfect the liquid, penetrate into the local system.

Hardness salts are dangerous for household appliances, even if the concentration complies with current regulations - no more than 7 ° W. At this level, a connected dishwasher can be damaged in 5-6 months of intensive use.

Rating of the best water purification systems for home and cottage

A large residential property is equipped with equipment that can remove harmful impurities with high efficiency. This control parameter is determined in the terms of reference with a margin. This solution will prevent the shortage of clean water at the highest volumes of consumption.

The best water purification system for a cottage is chosen without significant restrictions on overall dimensions. It is assumed that in such an object it is possible to allocate a separate room with sufficient usable volume. It is recommended to isolate the room in order to reduce the audibility of technological noise in the residential part of the house.

The initial investment for a correct calculation is supplemented with the costs of the operating period. To increase the accuracy of economic planning, a long term of 5-6 years is considered.

User Reviews

I bought on the advice of a friend the best water purification system for washing - reverse osmosis. However, I did not like the complete disappearance of taste at the exit. As it turned out, it was necessary to choose a more expensive kit with a mineralizer. After the corresponding modernization, there are no claims to the equipment.

Sergey, 28 years old, Vyazma

Installed an ion-exchange column-type kit in a private house. Automation performs without my participation only flushing. After 1.5-2 weeks, it is necessary to pour the tableted salt into the container for the regeneration solution. Changed the setting 4 times during the year with the help of the service department in order to optimize the operating mode after changing the inlet hardness level. Thinking about replacing equipment to reduce the hassle and cost during operation

Nikolai, 34 years old, Petrozavodsk

Tired of putting a new cartridge into the flow unit every 2 weeks. Replaced with a hollow fiber membrane filter. This device is more expensive, but to restore the working condition, it is enough to do a simple flushing

Elena, 45 years old, Ulyanovsk

what kind of drinking water is better and how is it purified?

Not every seemingly transparent liquid is truly pure: both well and tap water may contain a number of harmful elements. And if they do not manifest themselves when watering the beds or washing shoes, then the ingress of untreated water into the human body threatens with various negative consequences. About what water is better to drink, we will tell in this article.

At first glance, it may seem that only water used in production needs to be purified. Depending on the nature of the enterprise, it can be contaminated with all sorts of toxic substances or mechanical impurities. In addition, wastewater treatment is of great importance here, which protects the environment from irreparable harm.

Of course, industrial water treatment technologies differ from drinking water treatment methods. However, it is not worth considering that this procedure is a whim or reinsurance. In wells and artesian wells, water comes from collapsing rocks, and in pipes - from water pipes "rich" in corrosion. In both cases, there is a high risk of getting water with a high iron content, which is fraught with urolithiasis, intestinal disorders, problems with teeth and skin, as well as brown spots on plumbing and a yellowish tint to laundry that was white before washing. Many are familiar with the concept of hard water - when there is an excess of calcium and magnesium salts in the liquid. All due to the fact that water enters rivers and lakes from underground sources that flow in limestone layers. Hard water is no less dangerous than iron water and can lead to kidney stones, dry skin, dandruff and even hair loss. Hardness salts also negatively affect household appliances, significantly reducing their service life. It is also better not to cook food in such a liquid - this is especially true for meat, which even after a long cooking time will remain tough and tasteless. In industrial areas and regions, water with an unpleasant smell of hydrogen sulfide may be more common than others. Usually, large cities arose in the places of occurrence of ore, and hydrogen sulfide gas dissolved in water is just the same formed during the decomposition of protein as a result of the vital activity of oxygen-deprived bacteria. First of all, artesian wells drilled at great depths are at risk here. In addition to the unpleasant smell of rotten eggs, hydrogen sulfide can also seriously harm human health, up to severe poisoning.

Note
More than ninety percent of the world's sewage treatment plants use chlorine and its compounds to disinfect and decolorize water. This substance quite effectively kills pathogenic bacteria and microorganisms and is also inexpensive. At the same time, it is still impossible to drink chlorinated water, and it is unsuitable for water procedures: the chemical compounds contained in the liquid can again lead to dry skin, dermatitis and diseases of various internal organs.

The best option for water filtration in an apartment

The flow filter is considered to be the best water purification system for an apartment. It can be made in the form of a nozzle on a faucet, inside of which there is a grid and a carbon cartridge that takes away all harmful substances and impurities. In more modern models, there is also a diverter - a switch that allows water to flow through the filter or past it. The second version of the flow filter is installation under the sink. It works on the same principle, but has a more complex design, which, in addition to cleaning modules, includes a bracket for mounting on a wall, a device for connecting to a cold water pipeline, gaskets for connections and a separate faucet mounted on a sink. There is also a "mobile" type of filter - jug, which consists of two containers separated by a filter module. You can easily take such a filter with you on the road or when moving to a new apartment, but its filtration speed is several times lower. Flow filters cope with all the typical problems of tap water: unpleasant taste, hardness salts, as well as high levels of iron and chlorine.

At the same time, there is an alternative filtration method to chlorination - reverse osmosis. This is a process in which pressurized water passes through a semi-permeable membrane from a more concentrated to a less concentrated solution. This method has been known since the 70s of the last century, when drinking water was obtained in this way from sea water. Later, filters for domestic use were developed based on this technology. The main feature of the reverse osmosis filter is that it removes from the water both harmful elements (arsenic, chlorine, iron, heavy metals) and useful ones, including mineral salts. As a result, the resulting liquid becomes almost completely free of impurities.

What is the best water to drink? There is no unequivocal opinion whether such water is good for the body. Some experts believe that water only plays the role of a solvent in it and therefore must be crystal clear, while others are convinced that micronutrients must be contained in the water. At the same time, if the water that has passed through the reverse osmosis filter is intended for children or the elderly, it must be one hundred percent mineralized. This can be done with the help of additional cartridges.

A good example of such a household reverse osmosis filter is the PURE AquaCalcium filter, which replicates the natural way of saturating water with calcium. Tap water passes through three pre-treatment cartridges, which are designed to remove mechanical impurities, as well as residual chlorine and organic compounds. Then the water is sent to a reverse osmosis membrane, which purifies the water from bacteria, viruses, metals and hardness salts. After the membrane, water enters a special AquaCalcium cartridge, in which the first stage of mineralization takes place. Special filter technology mimics the natural speed of water passing through rocks. Due to this, the contact time of water with the mineral composition of the AquaCalcium cartridge increases and, as a result, a constant content of minerals is maintained in the purified water. The liquid accumulates in the tank, after which the second stage of mineralization takes place. Before entering the faucet, the water passes through a carbon post-filter, which contains high-quality activated carbon from coconut shells. The performance of this device is up to 280 liters per day.

The best water purification system for a country house

Water from a well and an artesian well can differ significantly in its properties from tap water, and the filter design will be different due to the peculiarities of the suburban infrastructure. What is the best water purifier to purify water? To select the most suitable device, it is recommended to do a preliminary water analysis. Otherwise, there is a risk of buying a filter that cannot cope with a high concentration of iron and hardness salts, or, conversely, spending money on powerful equipment, the capabilities of which were not needed.

Main filters are considered to be the best water purification systems for a country house. These are cylindrical flasks that are mounted in the water main, which gives the devices such a name. Main filters are very diverse and have several classifications:
