We spent greater than 60 hours researching and testing seven of the preferred water filter pitchers available on the market. We decided the ZeroWater – 6-Cup Pitcher to be one of the best water filter pitcher available on the market. ZeroWater is dear, however it deionizes the water to take away almost the whole lot. In the event you don’t want that degree of purification, the brand new Brita – Longlast Filter improves the style of faucet water and works about six occasions longer than the ZeroWater filter.

How we discovered the most effective water filters
We spent greater than 30 hours researching water, and the considerations and preferences that buyers having relating to their consuming water. We learn research on the kinds of contaminants that must be filtered out to supply protected consuming water, and the way the varied water filters available on the market work.
We additionally spoke with representatives and executives from the businesses whose water filter pitchers we examined to be able to study extra about how the totally different filters work, and what differentiates them from each other.
Our analysis additionally included a deep dive into sources extensively thought-about to be authorities on water security, together with: the Water High quality Affiliation and NSF Worldwide.
We learn critiques, boards, and Reddit threads to find out which water filters have been the preferred. Extra importantly, we seemed to see which filters have been licensed by NSF Worldwide, a third-party group that gives scores and certifications for water filters, to take away dangerous contaminants from water.
In 2017 our previous favourite pitcher and filter, the Mavea – Elemaris, was discontinued. For our 2018 replace, we searched far and extensive to seek out an equal alternative, however nothing was higher than what we’d already tried. Brita and ZeroWater are nonetheless the standout methods.
We switched our prime decide to the ZeroWater – 6-Cup Pitcher, with some caveats. The excessive degree of purification signifies that ZeroWater filters don’t final so long as we’d like, and for individuals with heavy mineral content material of their water it in all probability can be cheaper to purchase bulk bottled water on the grocery retailer.
ZeroWater now sells compact filters for an On-The-Go cup and Brita-compatible pitchers, however the anticipated life is simply 5 gallons, so we didn’t even think about testing them. We checked out various filter replacements that is perhaps simply nearly as good, however they weren’t truly cheaper than shopping for from ZeroWater. We additionally appeared round for a prefilter setup or bulk refill media and didn’t discover something easy sufficient to advocate for many households.
We noticed studies of improved efficiency in Brita’s new Longlife Filter (now licensed to take away lead) and determined to check it alongside our ZeroWater pitcher in a 2018 fall replace.
The 5 greatest water filter pitchers
Who can purchase a water filter pitcher
For those who don’t have already got a reverse-osmosis system, or another sort of water filtration system in your house, a water filter pitcher is a simple and handy solution to get clear, great-tasting water. Should you reside in a metropolis that has notoriously poor faucet water, having some sort of water filter system is much more essential.
Within the US, water suppliers are required to offer a “consumer confidence report” that lists testing outcomes for the water in your native provide system. You’ll be able to lookup a report or contact info in your native company on the EPA’s website right here.
Issues together with your water won’t present up on regional check, although: if in case you have a supply of contamination in your personal plumbing, or when you’re on a properly or different personal provide, it’s as much as you to get it examined. Many water providers or filter installers will check a pattern of your water at no cost, and typically you will get mail-in checks without spending a dime at hardware shops, however keep in mind that these exams are particularly designed to persuade you to purchase a remedy system.
All respected water filter pitchers (together with all 5 that we examined) are licensed to take away a selected listing of dangerous contaminants by NSF Worldwide, an unbiased not-for-profit company. Whereas every of the water filters we examined have totally different certifications, all of them considerably scale back dangerous contaminants within the water.
The profit of filtered water is primarily style. Even probably the most innocent particles can change the style of your water, whether or not you’re consuming it by itself or in a brewed beverage like your favourite espresso. Filters additionally take away remedy components like chlorine, which frequently have probably the most vital influence on water style.
Utilizing water filter pitchers may also be considerably inexpensive and fewer wasteful than putting in a reverse-osmosis system in your kitchen. “R-O” techniques dump quite a bit of water down the drain, and often take up helpful space for storing underneath your sink.
Please observe: None of the water filters we examined is licensed to take away organic contamination. In the event you get a “boil water advisory” in your space, it is best to boil your water for one minute (and let it cool) even should you run it by means of a top-rated filter system to enhance the style.
How we examined the pitchers
In an effort to decide the most effective water filter, we used a mixture of quantitative and qualitative checks to match every of the water filters. The following are the exams we utilized in our rating of our water filter finalists:
One of the primary checks we carried out was a blind style check. To conduct this check, every of our testers got a cup of water from every of the water pitchers, with out information of which pitcher every cup of water got here from.
For every cup of water, testers have been requested to inform us whether or not they agree or disagree with six constructive descriptive phrases, together with:
- Thirst quenching
They have been additionally requested to fee every cup of water utilizing two destructive descriptions:
The MAVEA water filter (discontinued) stood out by main in each classes — with the perfect common rating on constructive descriptions and the perfect (i.e. least damaging) on the adverse scores.
How shortly every water pitcher filters water
We additionally examined every filter to find out how lengthy it will take, on common, to filter one cup of water. Whereas one might argue that extra time could be essential for a extra thorough filtration, we nonetheless thought it was necessary to think about this metric — even when it wasn’t probably the most crucial issue.
For this check, the Brita filter carried out greatest, taking simply 40 seconds on common to filter one cup of water. On the opposite aspect, the PUR filter took a surprisingly lengthy three minutes and 40 seconds to filter one cup of water.
After performing some analysis, we thought the PUR filter we had could be faulty. Nevertheless, after making an attempt filters from two totally different packages, our outcomes have been primarily the identical.
Aside from the PUR outlier, the slowest water filter was the ZeroWater filter, which took a mean of 1 minute and 50 seconds to filter one cup of water. We spoke with the CEO of ZeroWater, Doug Kallam, and introduced this query up. He advised us that it’s true that ZeroWater filters take longer than different filters, largely as a result of of the ion-exchange course of that ZeroWater filters use to deionize the water.
The MAVEA water filter (discontinued), was proper within the center of the pack, averaging about 1 minute and 5 seconds per cup of water filtered.
Whereas our ergonomic testing was largely qualitative, we made some extent of in search of particular ergonomic parts on every water pitcher. Most significantly, we seemed to see whether or not the pitcher was snug to carry, even when it was utterly full of water.
We additionally checked to see how secure the pitcher was when positioned on numerous surfaces, together with tile, a desk, and inside a fridge.
Lastly, we made observe of any further options every pitcher had. Examples included the pour-through lid on the MAVEA and BWT pitchers and the spout on the ZeroWater pitcher.
2018 replace testing
For our 2018 replace, we pitted the Brita – Longlast Filter towards our new testers, a family of three in Orange, California, utilizing the identical methodology of double-blind taste-testing.
For controls, we additionally included unfiltered faucet water, bottled distilled water and water that had been run by means of used-up filters from Brita and ZeroWater that have been properly previous their helpful life. The “old” ZeroWater filter allowed between 005 and 007 PPM of TDS via, proper on the road for alternative; the “old” Brita filter had filtered roughly 50 gallons of water, additionally simply previous its anticipated life of 40 gallons.
Once we tallied all of the constructive and adverse style studies, we discovered that the outcomes have been surprisingly near outcomes from our earlier check on the workplace. From this new group of testers, constructive scores got here in a bit greater general, with unfavorable scores reserved for faucet water and the used-up ZeroWater filter.
It’s necessary to notice, nevertheless, that these testers have been utilizing a Brita system of their house for greater than a decade, however principally out of behavior. Once we requested them how efficient they thought their Brita pitcher was earlier than the check, they stated “it doesn’t seem to be doing anything.” They have been stunned at how simply they might inform the distinction between the style of faucet water and a normal Brita filter.
We found that the distilled water (which had been sitting on a shelf in its plastic jug for a couple of months) truly had a worse style than the faucet water, “almost like an artificial flower taste.” That is an uncommon outcome, however goes to point out that storing distilled water has its personal set of issues.
We requested our testers to rank the the style of the top-scoring filtered water earlier than we informed them something about tallied scores or manufacturers, they usually all picked the Brita – Longlast over the ZeroWater filter’s style, with the Brita commonplace cartridge coming in a extra distant third.
We needed to see how a lot distinction filter sort actually makes with style’s largest enemy, chlorine. We referred to as in a Hatch chlorine check package that may detect a .01 part-per-million distinction in complete chlorine.
The faucet water we examined had between zero.7 and 1 PPM of chlorine. We discovered that any water filter we tried, regardless of how a lot it had been used, would take away all detectable traces of chlorine. This lined up fairly nicely with what we present in taste-tests: the worst offenders for style are the simplest to take away.
Brita filters: Commonplace vs. Longlast
We needed to see if the brand new Brita – Longlast Filter was simpler at eradicating the dissolved solids in our water than the older Commonplace – Filters. The faucet water in our testers’ residence reads between 250 and 300 elements per million on an electrical conductivity tester (the ever present TDS tester): normal Brita filters don’t do something to scale back the TDS rely, however the brand new Longlast filter brings it right down to 200.
That 20% change between the Brita filters is sufficient of an enchancment that, with this family’s water, it gained the style check. After a number of weeks of use, although, it looks like no matter mechanism Brita is utilizing to get that increase is depleted and it reads the identical as an ordinary Brita filter.
Prime Decide: ZeroWater – 6-Cup Pitcher
Of all of the water filters we examined, none have been capable of create pure water as successfully because the aptly-named ZeroWater filter.
ZeroWater filters are totally different from all the opposite filters we examined. As an alternative of solely utilizing an activated carbon filter, ZeroWater filters truly deionize the water. In different phrases, the ZeroWater filter removes primarily every part reactive from the water itself — which is why they promote the truth that their filters produce a studying of “000” on a “total dissolved solids” (TDS) meter.
In unbiased laboratory testing, ZeroWater persistently beats each different water filter available on the market when evaluating the quantity of dissolved solids left within the water after filtering. This consists of every thing from harmful contaminants like lead, to contaminants that impression style greater than anything — chlorine, for instance.
The upsides of this are obvious, notably in areas the place water high quality is questionable and even harmful. For instance, the Flint water disaster left residents with consuming water that contained unsafe ranges of lead and different contaminants. Water filters corresponding to ZeroWater are capable of filter these contaminants out of the water and to supply water that’s protected to drink.
ZW will get rid of all dissolved solids. This leaves water tasting full pure. Apparently, this isn’t universally considered a great factor. That’s as a result of not all dissolved solids are dangerous. In reality, some of them, akin to magnesium, are useful in your well being and enhance the style of the water.
ZeroWater – 6-Cup Pitcher
If eliminating distilled solids is your goal, ZeroWater delivers best-in-class filtration. The ion-exchange know-how will not keep efficient for lengthy when you’ve received lots of minerals in your water, however it’s very constant and efficient whereas it lasts.

For a well-liked instance: Naturally carbonated bottles of water, corresponding to Perrier and Pellegrino, include excessive ranges of dissolved mineral solids, which contribute considerably to their taste profile.
We spoke with the CEO of ZeroWater, Doug Kallam, and he advised us that ZeroWater does the truth is take away the “taste profile” of water consequently of the deionization course of. The plus aspect of that is the truth that primarily all heavy metals are eliminated, at charges notably greater than different filters available on the market.
Fascinating, throughout our testing we discovered that some individuals didn’t just like the style of ZeroWater, and a few even thought it had a “chemical” style. That is fascinating, as a result of as we talked about ZeroWater is scientifically confirmed to include the fewest chemical compounds (in the event you exclude the chemical H2O). Our concept is that we’re all so used to there being dissolved solids in our water (each faucet and filtered) that it tastes unusual to us once we drink water that’s genuinely pure.
Issues we appreciated concerning the ZeroWater pitcher
After utilizing the 10-cup ZeroWater pitcher for a couple of years, we now have to confess that it’s a bit greater than we like. We tried out the 7-cup pitcher, and it’s simpler to pour from than most 10-cup pitchers. Not solely is the crammed pitcher lighter, however the spout design is much less more likely to dribble or splash once you’re filling a narrow-neck water bottle like our favourite Klean Kanteen. The spigot on the base of the 10-cup pitcher was a neat concept, however in follow it was so sluggish to empty, we stopped utilizing it. So, we’ve switched our suggestion to the 7-cup mannequin.
The filters are giant, however don’t require any presoak, which makes changing the filters a lot simpler than filters which require a presoak course of being getting used for consuming water.
We additionally like the truth that the ZeroWater pitcher comes with a TDS meter. Earlier than you ask: sure, we checked the outcomes towards one other TDS conductivity meter, and no, ZeroWater isn’t tricking you with some sort of rigged tester that solely works with their very own filters.
ZeroWater directions advocate that the filter get replaced when the meter reads “006”. That is useful since you don’t have to recollect how lengthy it’s been — or estimate what number of gallons you’ve poured — when changing a filter. As an alternative, you’ll be able to merely examine on the TDS meter and exchange when the studying hits zero06.
Lastly, ZeroWater has the most effective recycling program of all of the water filters we examined. ZeroWater will truly pay $5 for every filter that’s returned. Because of this clients might be rather more incentivized to carry onto the filters and ship them again, decreasing contributions to landfills.
Issues we didn’t like concerning the ZeroWater pitcher
ZeroWater filters are the costliest of the pitchers we examined. Whereas that is offset by occasional e-mail promotions and the recycling rebate, clients will nonetheless have to spend extra money to filter water with ZeroWater than another filter — notably in the event that they reside in a metropolis the place faucet water has excessive ranges of dissolved solids.
Finally, ZeroWater is a wonderful choice for many who need the purest water attainable. If you wish to add again some taste, a slice of lemon does the trick.
Up to date testing
The efficiency of the ZeroWater filters could be very constant, however costly. We appeared round for options which may permit cheaper alternative of the ion change resin beads, however on the entire, the filter matches in at an uncomfortable center floor: It’s simply barely low cost sufficient to purchase these filters that a DIY refill or regeneration of the media simply isn’t going to be worthwhile for most individuals.
Should you’ve acquired greater than 300 PPM of dissolved solids in your water, although, ZeroWater cartridges may want alternative very often. A reverse-osmosis system that features an ion-exchange stage is a greater purchase for filtering greater than a gallon per day of mineral-rich water.
On the entire, the suitability of ZeroWater relies upon completely on what’s in your water and the way badly you need to filter it. In case your water has a low sufficient mineral content material (round 200 PPM) that the filter lasts for a month, you’ll be very proud of the consistency of the water you get.
- ZeroWater filters use ion change know-how to take away virtually all dissolved solids.
- ZeroWater’s minimal style got here in an in depth second in our blind choice check.
- The compact 6-cup pitcher is straightforward to pour from, even whereas it’s nonetheless filtering.
- For those who’ve obtained quite a bit of minerals to filter out, the ZeroWater filters could be costlier than bottled water.
Finances decide: Brita – 10-Cup Pitcher + Longlast Filter
Brita is probably probably the most well-known model of water filter pitchers, and they’re largely liable for the expansion in reputation of filter pitchers because the late 1980s once they first got here to the U.S. market. They’re the undisputed market chief, with greater than two-thirds of the general water filter pitcher gross sales.
The commonplace Brita filter doesn’t take away the quantity of contaminants that a filter like ZeroWater does. With the brand new Longlast filter, mannequin OB06, Brita is making an attempt to up their recreation: Within the aftermath of the Flint water disaster, it’s no mistake that “99% lead reduction” is entrance and middle in Brita’s promotional materials.
Which filter you select is certainly going to be a matter of selection for most individuals. Brita’s system is enough to enhance style, and each the NSF and different unbiased exams present it’s going to take away heavy metals. For the overwhelming majority of us, chlorine discount goes to be the most important concern, and safeguarding towards unintentional publicity to steer, cadmium and mercury is a bonus.
Once we checked our water with a chlorine reagent check, although, we have been stunned to seek out out that chlorine discount was similar between a used-up Brita filter and a brand new one. Even a recent Brita filter (of both the previous Normal or new Longlast sort) didn’t change the style of mineral-heavy nicely water when examined it.
Brita – Longlast Filter
Brita’s new filter lasts for 120 gallons and filters out heavy metals like lead, so it is a particular enchancment over the previous system. If you’d like the cleanest water, although, it is nonetheless not as efficient as ZeroWater.

Brita’s new Longlast filter is a transparent winner for the fee of filtering chlorine and different simply filtered contaminants. The Longlast can also be low cost sufficient that it’s value making an attempt a blind style check your self should you’ve already received an older Commonplace filter available.
Sadly, Brita doesn’t promote any pitchers packaged with a Longlast filter, however the 10-Cup On a regular basis Pitcher or another commonplace Brita pitcher can use the brand new blue filter.
- The Brita On a regular basis Pitcher removes the worst-tasting substances (like chlorine) from most faucet water.
- Brita’s new Longlast filter provides higher efficiency filtering metals like lead (However you must purchase it individually).
- Brita’s carbon filters don’t take away mineral solids to the extent ZeroWater does.
- This technique filters far more water than ZeroWater earlier than the filters cease working, so prices are a lot decrease.
The different merchandise we examined
The different three water filter pitchers we examined all carried out properly. All three have been capable of filter out vital ranges of contaminants in response to NSF Worldwide, and had strong design and construct high quality.
BWT Designer Water Filter Pitcher
The BWT pitcher has an fascinating and progressive design, and the filter itself truly provides magnesium to the water, presumably to enhance style and improve the well being advantages of the water. Nevertheless, some of our style testers didn’t like the flavour of the water filtered by the BWT pitcher.
PUR 7-Cup Final Pitcher
The water produced by the PUR water filter was polarizing amongst our style testers. Some liked it, whereas for others it was their least favourite. After performing some digging, we discovered that those that had a choice for PUR water both used PUR filters of their house already, or had used them prior to now — which fits to point out the significance of familiarity as regards to style.
From a security perspective, PUR is on par with the opposite filters we examined (excluding ZeroWater), nevertheless our largest problem with the filter was how sluggish it filtered, averaging almost four minutes to filter 1 cup of water after a number of checks and three totally different filters.
The suggestions we discovered on-line was combined, with some reporting comparable tales and others saying the filters wanted to be “shaken and mixed”. Finally, we expect there are merely higher choices to select from, with or with out sluggish filtration occasions.
This was one of our prime picks, however in 2017 MAVEA stopped distributing its merchandise in North America so we’ve moved it to our “other picks” part, however don’t need to dismiss its high quality or unique rating.
In 2018 have seen the filters come again in inventory, which is nice information for many who purchased one of these techniques a number of years in the past. Regardless of indications they’re excited about promoting in North America once more, there’s nonetheless no signal of the pitchers at retail.
The design of the MAVEA stood out as notably excellent. The use of rubberized supplies — each on the 4 ft and the deal with — considerably enhance stability when holding the pitcher or putting it on a floor. General, holding the MAVEA pitcher is snug, balanced, and secure — whether or not the pitcher is totally empty or utterly full.
In contrast to many of the opposite water filters available on the market (together with a number of we examined), the MAVEA filter doesn’t have to be presoaked earlier than use.
MAVEA additionally claims that the water filter works extra persistently than different filters, because of its design. Whereas we didn’t check this ourselves, the overall consensus amongst reviewers and the others we spoke to signifies that MAVEA filters do appear to be extra constant of their filtration lifecycle.
Lastly, one sometimes-overlooked function is MAVEA’s recycle program. Any time you’ve gotten 6 or extra used MAVEA filters, you need to use the corporate’s contact type to print out postage to ship the filters again to MAVEA at no cost. MAVEA then recycles 100% of the supplies within the filter — which suggests you possibly can drink clear water with out worrying about contributing to environmental injury.
There was tons to love concerning the MAVEA pitcher. We hope they will convey a system to market in North America once more.
The backside line
Should you’re on the lookout for water that’s as pure as attainable, and utterly free of all dissolved solids (each useful and dangerous), the ZeroWater filter is a superb choice, nevertheless you’ll be paying a bit of greater than common for his or her extra thorough filters.
Finally, any of the 5 water filters we examined will take away some contaminants out of your faucet water, they usually simply enhance the style by eradicating chlorine. Brita’s Longlast filter is by far probably the most value efficient, filtering 3 times extra water than most of the others and extra heavy metals than the essential Brita. You’ll have to purchase a Brita Pitcher to go together with it, and we appreciated the 10-Cup On a regular basis Pitcher.
Our Prime Decide: ZeroWater – 6-Cup Pitcher
A superb selection, offering the purest water. There isn’t any presoaking and even a filter recycling program to scale back your value and waste.
