Best Water Filter Pitcher for 2022

The right water pitcher can improve the taste and quality of your drinking water. If you're a dedicated bottled water drinker, a good home filter system or filtering pitcher could save you hundreds of dollars each year. And water filter pitchers couldn't be simpler to use.

Brita is the best-known water filter pitcher brand, but that doesn't mean it's the best at removing impurities. We tested several top-rated water filter pitchers, with prices ranging from under $20 to over $100 in order to suss out the top-performing filters in a category teeming with options.

In our initial round of water filter pitcher testing, one model left the rest of the pack in its dust. In this most recent round, that same pitcher, the $22 ZeroWater pitcher kept the top spot, removing nearly all of the total dissolved solids (or TDS) and leaving a clean-tasting glass of h3O. While this one pitcher has the best technical results in our TDS-removal testing and is our top recommendation for most people, there are other water filter pitchers in the group also worthy of consideration.

The best water filter pitchers for 2022

ZeroWater

Best overall water filter pitcher

Sep 2022

The ZeroWater was by far the best water filter pitcher of the bunch in both this and the previous rounds of testing. This water purifier pitcher is fairly affordable and sturdy and it comes in a few sizes all of which use the same filter. Those include a smaller 10-cup round pitcher, 23-cup dispenser with spigot and even a massive 5-gallon water jug that can be fitted onto a water cooler.

In our testing, the ZeroWater filter was pitcher perfect, removing all of the TDS from the water we ran through it, finishing with a 0 average reading. ZeroWater is so confident in its filter products that each model comes with a TDS water quality tester to see for yourself how well it works. We used our own tester in addition to the one included and the filter delivered a perfect TDS score on both.  

ZeroWater pitchers are a bit more expensive than Brita and Pur but by no means a luxury purchase with some of the smaller dispensers starting at around $25. Each one uses the same 5-stage filter so you can bet that you'll get similarly clean water no matter which unit you decide on. A pitcher filter replacement two-pack costs $30 and each one is supposed to last for up to 40 gallons. For comparison, Brita and Pur, on the other hand, sell each of their filters for just $7 -- and claim to have the same 40-gallon filter life.

Brita Standard Metro Filter Pitcher

Best budget filter pitcher

Brita is probably the best known of the water filter pitcher brands and it performed well in our testing, second only to the ZeroWater in the overall removal of dissolved materials. The Brita removed about 40% of the TDS. Not a bad showing but still significantly less than the winner.

This model happens to be about $13 cheaper than the cheapest ZeroWater model and is one of the most budget-friendly water filter pitcher options out there. To make things even more cost-efficient, the replacement filters can be had for about $3 if you buy them in a multipack. Each one is said to filter 40 gallons of water, enough for roughly two months of steady use (the same lifespan as ZeroWater).

While I wasn't in love with the build of the Brita -- the plastic feels a bit cheap -- it is just 1.32 pounds which is less than half the weight of the ZeroWater. If you have small kids or folks in the home who can't lift a heavy pitcher, this may be a good pick.  

Brita also makes a "Longlast" filter that's designed to last three times as long as the standard filter. We tested a Longlast and found it performed significantly worse than the Legacy (standard) filter. Plus, it's more expensive so I'd suggest sticking with the Legacy if buying a Brita.

Seychelle ph30

Best pitcher for adding alkaline to your water

If the goal is to add alkaline to your water, then you'll want a completely different model. In a previous round of filter testing, we ran pH readings (measurements of how acidic or basic your water is) range from 0 to 14; 7 is a neutral reading. 

Despite conflicting research on the topic, some people attribute health benefits to more basic (or alkaline) water. As a result, select companies make water pitchers with filters that actually add nutrients as your tap water passes through. 

The $70 Seychelle ph30 pitcher took tap water from an already basic reading of 8.39 to 10.1, the largest increase out of the three alkaline pitchers in my test group. This pitcher's water filtration system uses two filters at a time, but they are supposed to last for up to 200 gallons. A replacement filter two-pack costs $50.

Pitcher talk


To get started, here's a list of the six pitchers we tested:

One key thing to consider from this chart is the estimated life of each pitcher filter versus its cost. The Brita Metro Standard and Everyday models, the Pur Plus and the ZeroWater pitcher all have a lower estimated filter life of up to 40 gallons. While the Brita filter and Pur filter models cost $7 each, the ZeroWater filters cost $15 each (but are sold in a $30 two-pack). 

Can you spot the ZeroWater filter? It's the one on the far right. 

Megan Wollerton/CNET

As you can see in the picture above, the ZeroWater filter on the far right is massive compared to others. Of course, that doesn't necessarily equal better performance but in this case, the ZeroWater did soundly outperform the others in removing contaminants. ZeroWater claims to have a five-stage filter that's better at removing particles while preventing mold from growing with use. Based on our testing results, it seems the brand may be onto something. 

(Keep in mind that filter life will vary based on the quality of your tap water and how much your filter has to "work" to remove impurities.)

How we test water filter pitchers

To test these water filter pitchers, we washed each one with mild soap and water, then followed the individual manufacturer instructions for soaking, rinsing or otherwise prepping filters for use. Then we filled a marked mason jar glass with 16 ounces of tap water and used an Orapxi water quality tester to measure and note the TDS present. 

While the results of my tap water varied slightly each time I filled a fresh glass with 16 ounces the TDS of the water used always read between 47 and 50 ppm, or parts per million. (Read more about TDS here and here.) 

Then we poured all 16 ounces into a water filter pitcher, waited for it to filter all the water, poured it into a new glass and took the readings again. For nonalkaline pitchers, you should expect to see a drop in the TDS readings, as impurities and other minerals are removed from the water. We repeated these steps a total of three times on each of the pitchers. 

TDS meters are not sophisticated enough to decipher which impurities, nutrients and other minerals each filter manages to remove (or add, in the case of the alkaline pitchers). For that reason, measuring TDS alone as an indicator of water quality has some limitations. But, in general, for a standard filtered water pitcher, we want to see a decrease in the TDS reading. Examples of the most common TDS include "calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, nitrate, and silica," according to the US Geological Survey.

In a previous round of testing, we ran three alkaline water filter pitchers through a pH test -- Clearly Filtered, Invigorated Water pH Vitality and Seychelle ph30. All saw an increase in both the pH and the TDS, since they're designed to add minerals to your water, but the Seychelle saw the biggest pH increase which is why we've listed it as the best pitcher to buy if you want to add alkaline to your tap water. 

Here's a table of our most recent TDS removal test results. The data represents an average of three test runs for each filter pitcher. 

Test results


 TDS (% change)
Brita Metro Standard -45. 6
Brita Everyday -45. 6
Brita Longlast -3. 1
Larq self-cleaning -2. 2
Pur Plus -6
ZeroWater -100

The ZeroWater pitcher managed to reduce all of the total dissolved solids in my tap water, from an average initial TDS reading of 57 ppm down to zero -- which may help explain the name. Both Brita pitchers with the standard filter tied for second place, with a reduction of TDS from 57 down to 31 (a 45.6% decrease). 

Water taste was a bit trickier to measure, but every pitcher did help reduce the slightly metallic taste of my tap water. Unsurprisingly, the ZeroWater pitcher model tasted the best, with no discernible metallic taste or scent. 

Overall, the ZeroWater (ZP-010) made our job pretty easy in both rounds of testing. It completely dominated in terms of removing TDS and also happened to have one of the sturdiest designs -- second only to the expensive Larq self-cleaning pitcher. But there are other good options here too: The Brita Metro Standard is a great budget filter pitcher that weighs less than ZeroWater's pitchers and has cheaper replacement filters. The Seychelle ph30 is a great pitcher pick if you want to add alkaline to water.

One thing to note is that we're really testing the filters here and not the pitcher itself. Because most home filter pitchers made by a single brand will use the same filter, you can bet that no matter which size or shape dispenser you choose, the filter should do the same job, for better or worse. ZeroWater, for instance, has a line of about six pitchers, jugs and dispensers in various sizes -- all of which use the same very effective five-stage filter. The one caveat within the brands we've tested here is Brita which offers a LongLast filter that did not perform as well as the Legacy Brita filters.

Another big takeaway is just how widely filtered water pitchers can vary, both in terms of performance -- and even in terms of their key function, as in the case of the alkaline pitchers. As long as you identify your needs before you buy, you're bound to find the right filtered water pitcher for you.

Best water filter pitcher FAQs

How does a water filter pitcher work?

These handy kitchen gadgets work by allowing water to pass through a filter into a reservoir and removing impurities and contaminants in the process. To operate a typical water filter pitcher, you'll simply pour water from the faucet and let it drip down into the bottom where it's ready to be poured and consumed. This generally takes one or two minutes and you may need to fill the top reservoir twice or even three times and let it filter slowly down in order to fill the pitcher completely.

What contaminants should a water filter pitcher remove?

Most water filter pitchers will improve the taste and smell of drinking water by ridding it of odorous chemicals such as chlorine. Some more expensive or high-quality models also remove heavy metals, pesticides, PFAs, pathogens and other contaminants. Each water filter pitcher should state clearly on the packaging or website the exact materials it is intended to remove from water.

Which water filter pitcher removes the most contaminants?

In our testing, it was fairly clear which water filter pitcher removed the most contaminants. The Zero Water pitcher, while significantly bigger and more expensive than the other pitchers, removed all of the dissolved materials we were testing for. The Brita filter pitchers came in second place and also removed a substantial amount of contaminants.

While we haven't tested them yet, there are more elaborate water filters that you can have built into your sink from brands including Aquasana, Hydroviv and Berkley. These water filters may net better results but will run you in the $200-$500 range and require some form of installation which could incur even more costs.

Do water filter pitchers remove bacteria?

No. Water filter pitchers will remove many harmful contaminants like lead, copper, chlorine and organic compounds that affect the taste but they will do nothing to kill bacteria. Your tap water should already be treated for bacteria but if you're concerned about it, a standard water filter is not going to help.

In fact, if left unchanged for long periods of time a water filter itself could build up grime that could potentially cause bacteria to grow and permeate your water. Because of that, be sure to change your filter regularly as prescribed by each brand.  

How do I clean a water filter pitcher?

The most important thing you can do to keep your water filter pitcher clean is to change the filter. Most filter pitcher brands including Brita and Zero Water recommend replacing the filter after about 40 gallons but this number varies by model.

The bulk of the water pitchers that we tested can and should be cleaned like any other piece of plastic kitchen gear every few weeks. You can remove the filter and rinse them by hand with hot water and soap, making sure to fully rinse the pitcher so as not to leave soap residue. Most water filter pitchers are dishwasher-safe as well. Just don't forget to remove the filter which should never be cleaned with soap.

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 not only help improve the flavor of your water but also protect you from impurities such as rust particles and harmful contaminants such as bacteria and lead. Sure, bottled water is easily available as a quick and (initially) cheap solution, but water filters are more sustainable—and can save you money in the long run.

There are, however, 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.

"Be sure to do your due diligence as a consumer and compare filters and replacement cartridges," says Rick Andrew, Director of NSF International's Global Business Development. "If something seems too good to be true, then there is a good chance it may be a counterfeit." 

Do keep in mind 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 consumers who get water from their city, a Consumer Confidence Report is sent annually with the water bill.

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 filtering 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 for easy dispensing 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 the water.

This filtering system uses five separate stages of filtering 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 in the sink or counter that can accommodate the new faucet.  Still, most reviewers like that the instructions were very clear and that the system was 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-out or handheld faucets.

Most water filtration systems are designed for kitchen use, 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 shower and tub will thank you, too. 

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.

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."

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.

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. Online users particularly praised the ease of installation, even those with little or no experience with plumbing, and they also praise the easy method for filter replacement when it’s necessary. 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.

What to Look for When Buying a Water Filter

By Marshall Bright

Purpose

There are two reasons to get a water filtration system, explains Rick Andrew of NSF International, a health and safety standards testing company that certifies water filtration systems. For drinking water in the U.S., 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.

However, there are still times when you may want a system that can filter out contaminants, like lead or man-made chemicals. 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 it’s 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 also want to consider your household’s water consumption when purchasing a filter. A smaller pitcher for a dorm or apartment, for example, may be fine, but for larger households (or if you want to filter water for cooking as well as drinking), 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 easy to give up on it, and simply go back to drinking unfiltered water from the tap. 

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 them in, including price, availability, and how often they need to be replaced when deciding on your filtration system.

Cost

Water filtration systems can either cost thousands of dollars, or if you’re getting a small pitcher, 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 water 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 Andrew, "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. 

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 it 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 dishes or your hands 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; 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

Water bottles can also filter water and thus be certified by the NSF and ANSI. They can filter water as you fill the water bottle or as you drink it. 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 water bottles. But, many home water filtration brands and filters are designed to remove contaminants from treated water. If you want a water filter for hiking or getting water from sources like creeks and rivers, you’ll need to be extra sure that the filtration system you're buying can remove bacteria and other organisms found in nature. 

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 contaminants for taste, as well as mercury and other contaminants, and 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, like 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 Rick Andrew recommends 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. 

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. 

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.
