1. Best value: Brita – Monterey with Longlast Filter

The Brita – Monterey comes from the nearly well-known manufacturer of h2o filter pitchers, and Brita is largely responsible for the growth in popularity of filter pitchers since the late 1980s when they were introduced to the U.South. market. Brita is the undisputed marketplace leader, with more than than two-thirds of overall water filter pitcher sales.

The standard Brita filter doesn't remove much more than than chlorine for near households. With the new Longlast filter, Brita is trying to up their game: In the backwash of the Flint water crisis, and with other cities discovering the liability of lead pipes in older homes, information technology's no mistake that "99% lead reduction" is front and center in Brita's promotional material.

Things we liked

Brita'south system improves the taste of your tap h2o, and independent tests testify it will remove heavy metals. For the vast majority of united states, chlorine reduction is going to be the major business concern, and safeguarding against accidental exposure to atomic number 82, cadmium and mercury is a peace-of-mind bonus.

The Longlast isn't as thorough as the carbon cake used in Brita's faucet-mountain organisation, just it is certified to clean out easier-to-take hold of organic compounds, such as benzene, and pharmaceuticals similar ibuprofen. In a blind examination, our judges couldn't tell apart the water from a Brita Longlast pitcher filter and the Brita faucet filter, just they each beat the old-style non-lead-removing filter.

The biggest win for Brita is value. These filters are certified to concluding for 6 months or 120 gallons. That'due south even longer than the carbon-block filters in their faucet-mount systems.

Brita - Monterey with Longlast Filter

Brita's new filter lasts for 120 gallons and filters out heavy metals similar lead, so it'due south a definite comeback over their old organization. It withal won't do much for well water, though.

Things we didn't like

The ii Brita pitchers we tested that are now available with the Longlast filter included, the Everyday and Monterey, are 10-loving cup pitchers. They're heavy and a flake clunky to lift and cascade from. (You lot tin also fit the new filters into basically whatever Brita pitcher, like the 5-cup Metro.)

In a few instances, nosotros too saw unfiltered water seeping out at the front of the reservoir if we tried to pour the start cup of h2o out while the acme of the pitcher was still total. That's not an uncommon problem (the PUR pitcher volition pop the top and spill all the water if you lot effort this) but it'due south frustrating that so much work has gone into making elaborate dust-covers without fixing this basic part of the pitcher.

When nosotros checked our water with a chlorine reagent exam, we were surprised to notice out that chlorine reduction was identical between a used-up Brita filter and a new one. The biggest taste improvement for near tap h2o is clearly the easiest task, unless yous adopt the mineral-gratis non-flavor of ZeroWater.

Even the new Brita Longlast filter, which removes slightly more minerals in a carefully engineered system to have out atomic number 82, won't do much to modify mineral-heavy well water. If you just want to remove odors or set your mind at ease nigh pb and pesticides this kind of filter might be perfect, but it won't finish hard-water calibration from taking over the insides of your favorite Keurig.

If you're looking for a reliable improvement in the sense of taste of chlorinated water or an efficient manner to forestall potential pb exposure, Brita makes a expert bullpen with a great filter.

Key takeaways:

The Brita – Monterey Pitcher with Longlast Filter removes bad-tasting chlorine and dangerous metals similar pb.
Brita's filters don't remove minerals the way ZeroWater does.
Many people prefer the natural gustation of the minerals in their tap water, and Brita leaves them in.
This filter lasts longer than any other nosotros've tested, so ongoing costs are low.

2. The purest h2o: ZeroWater – vi-Loving cup Pitcher

Of all the water filters we tested, none were able to create pure h2o as finer as the aptly-named ZeroWater filter. It's besides the nigh expensive, unless yous've already got generally mineral-free water.

ZeroWater is different from all the other filters we tested. Instead of relying on activated carbon granules to do most of the filtering, ZeroWater filters are total of mineral-alluring ion substitution resin, plus some of the usual carbon media to remove chlorine and the piece of cake-to-grab organic materials.

In other words, the ZeroWater filter removes essentially everything from the water itself — which is why they advertise the fact that their filters produce a reading of "000" on a "total dissolved solids" (TDS) meter. The upsides of this are credible, particularly in areas where water quality is questionable or even dangerous.

Dissolved minerals aren't commonly a bad thing, though. Some of them, such as magnesium, are beneficial for your health and for the taste of your water. There's some controversy effectually the practice of drinking mineral-gratis water, and one study recommends monitoring your mineral levels and taking supplements if yous're not getting calcium, magnesium and sodium in your water.

Purest H2o: ZeroWater

If eliminating contaminants is your aim, ZeroWater delivers all-time-in-class filtration. The ion-substitution engineering science won't stay effective for long if you've got a lot of minerals in your water, just information technology'southward very consequent and effective while information technology lasts.

During our testing we found that some people did not similar the taste of ZeroWater, and some even said information technology had a "chemical" taste. This is ironic, since it's the absence of chemicals that leads to this result, simply if you lot're used to the minerals in your water the modify will exist easy to distinguish. Even so, other testers (peculiarly those with reverse-osmosis systems at home) loved the taste.

After using the x-loving cup ZeroWater bullpen for a twelvemonth, we had to admit that it'due south a bit bigger than nosotros'd like. We tried out the 6-loving cup pitcher, and it's easier to pour from. The spigot at the base of operations of the ten-cup pitcher was a neat idea, but in exercise it was so slow to drain, and we rarely used information technology. So, we've switched our recommendation to the 7-cup model.

Things we liked

We also similar the fact that the ZeroWater pitcher comes with a TDS meter. Before you ask: Yes, we checked the results against another TDS conductivity meter, and no, ZeroWater isn't tricking you with some kind of rigged tester that only works with their own filters.

ZeroWater instructions recommend that the filter be replaced when the meter reads "006." This is helpful considering yous don't have to guess how many gallons you've poured when replacing a filter. Instead, you tin can simply check on the TDS meter and supervene upon the filter when the reading hits 006.

If the cost of filters is a turn-off, information technology'southward worth noting that ZeroWater has the all-time recycling programme of all the h2o filters we tested. ZeroWater volition actually pay $five for each filter that is returned. This means that customers take an incentive not to fill up landfills with filters, and the ion-exchange media inside can actually exist regenerated.

ZeroWater didn't succeed in designing a perfect pitcher, but at to the lowest degree the top is less likely to leak or pop off if you lot cascade while the top reservoir is full. The fill port comprehend isn't as convenient as the flip-upward design on the PUR or Brita, only at that place'southward nothing incorrect with it.

Things we didn't like

ZeroWater filters are some of the most expensive pitchers we tested. While at that place are occasional electronic mail coupons and the recycling rebate helps, customers volition still need to spend more money to filter water with ZeroWater than any other filter — peculiarly if they live in a urban center where tap water has loftier levels of dissolved solids. We looked around for alternatives that might allow cheaper replacement or regeneration of the ion-exchange resin beads, but this process is rare outside of industrial or laboratory employ.

On the whole, the filter fits in at an uncomfortable eye ground. It's inexpensive enough to buy these filters that it'southward usually a feasible alternative to majority bottled water. But if y'all've got more than 300 PPM of dissolved solids in your water, ZeroWater cartridges will likely need to be replaced every 15 gallons or less. A water softener and reverse-osmosis system might still be cheaper in the long run for some well water.

Ultimately, ZeroWater is an piece of cake-to-use pick for those who desire the purest water possible but can't install a reverse-osmosis system. If you lot desire to add dorsum some flavor, a squeeze of lemon does the play a joke on nicely.

Key takeaways:

ZeroWater filters use ion-substitution engineering to remove nigh all minerals from your water.
This gustatory modality was a hit with some of our testers, but others prefer the natural mineral season.
The compact 6-cup pitcher is easiest to pour from, even while it'due south withal filtering.
If you've got a lot of minerals to filter out, the ZeroWater filters might be more expensive than bottled water.

Other products we tested

We've tested The other three water filter pitchers we tested all performed well. All three were able to filter out significant levels of contaminants and had skilful blueprint and build quality.

PUR 7-Cup Ultimate Bullpen

The water produced past the PUR water filter was polarizing among our taste testers. Some loved information technology, while for others it was their least favorite. After doing some earthworks, we institute that those who had a preference for PUR h2o either used PUR filters in their home already, or had used them in the past — which goes to show the importance of familiarity when it comes to taste.

From a prophylactic perspective, PUR is on par with the other filters we tested (excluding ZeroWater) so long equally yous use the "Ultimate" filter with the white cap for lead reduction. The bullpen itself is fine, but information technology doesn't distinguish itself except in the twist-lock arrangement that tells you the filter is sealed.

Our biggest event with the PUR was how slow it filtered, averaging about 4 minutes to filter 1 loving cup of water after several tests and three different filters.The feedback we found online was mixed, with some reporting similar stories and others saying the filters needed to be "shaken and mixed."

Ultimately, we think there are merely ameliorate options to choose from, with or without slow filtration times. Brita'due south Longlast filter lives upwardly to its name with triple the filter life of PUR'southward filters, and then if you lot're not interested in a cypher-mineral taste profile that's our pick.

Conspicuously Filtered

In 2019 we took a adventure on testing the non-certified Clearly Filtered water filter pitcher, to meet how much there is to lose or gain with higher levels of filtration in a arrangement other than the expensive ZeroWater.

The losses are pretty clear: cost and speed. The refills for this arrangement sell for more $40, so the ongoing cost of ownership is about the same as a ZeroWater system in most cases. If you're handy with a hole saw, yous can also get a opposite-osmosis system for near the same up-front price as the Clearly Water starter kit.

The Clearly Filtered pitcher took ten minutes to filter ane loving cup of water. This kind of performance makes the 3- and 4-minute times for Brita and PUR atomic number 82-removing filters seems speedy past comparison. It'due south non a hindrance to an occasional glass of water throughout the mean solar day, simply if y'all discover yourself filling three or iv extra-big h2o bottles before a family outing it could be a major headache.

Clearly Filtered doesn't use a certifying authority like NSF or the Water Quality Clan to test their products, but the results they post on their website are believable because of the long filtration time. Still, this organisation isn't giving yous the purified gustation of ZeroWater, and the cost is almost equally loftier.

BWT Designer H2o Filter Pitcher

We included the BWT pitcher in the first circular of our tests, and information technology has an interesting and innovative design. The filter itself actually adds magnesium to the water, presumably to improve taste and increment the health benefits of the water. However, some of our taste testers did not similar the flavor of the h2o filtered by the BWT pitcher.

BWT has their filters certified by the Water Quality Association, but they're merely covered for cadmium, copper and mercury, non lead.

How nosotros selected

We've been testing h2o filters since we started this website, and nosotros've spent more than 60 hours researching the concerns and preferences of consumers who love to stay hydrated.

In our starting time round of research, we read studies on the types of contaminants that need to be filtered out to produce safe and great-tasting drinking water, and how the various water filters on the market place work.

We also spoke with representatives and executives from the companies whose water filter pitchers we tested in order to learn more about how their filters piece of work, and what differentiates them from 1 some other.

Our research too included a deep dive into sources widely considered to be authorities on water safety, such as the Water Quality Association and NSF International, and we relied on their testing to gauge the effectiveness of manufacturer claims.

We scoured reviews, forums, and Reddit threads to determine which water filters were the well-nigh popular and which filters take problems.

Updates

In 2017 our old favorite pitcher and filter, the Mavea – Elemaris, was discontinued. For our 2018 update, we searched far and wide to detect an equivalent replacement, simply nothing was better than what we'd already tried. Brita and ZeroWater are notwithstanding the standout systems.

We switched our top pick to the ZeroWater – six-Cup Pitcher, with some caveats. The extreme level of purification means that ZeroWater filters don't terminal as long as we'd like, and for people with heavy mineral content in their water, it would often exist cheaper to buy majority bottled water.

In 2018 we re-tested our top picks afterward Brita started selling a lead-removing filter. In 2019 we tested a new version of the Brita pitcher and besides tested the Clearly Filtered bullpen, which removes fluoride.

How we tested

In order to determine the best water filter, we've used a combination of quantitative and qualitative tests to compare seven different water filters, and we've compared them with faucet-mount and reverse osmosis systems. Looking back at all of the testing we've done, nosotros call up your choice should exist based on a good understanding of the tradeoffs, rather than an assumption that one product will be the all-time for everyone.

H2o Filter Pitcher	Seconds to Filter i Cup	Minerals Remaining (Starting 500 PPM):	Filter Cost per Gallon	Removes Pb
Brita – Longlast	188	300	$0.09	Yes
ZeroWater	110	0	$0.33	Yeah
PUR – Pb Reduction	230	450	$0.18	Yes
Conspicuously FIltered	730	400	$0.46	Yes
BWT	45	425	$0.15	No
Brita – Standard	40	350	$0.x	No

Mineral removal and sense of taste tests

One of the first tests we conducted was a blind sense of taste examination, but over the years nosotros've been surprised at how extreme the private opinions on this ranking tin can exist. In three different bullheaded tests with groups of function workers, friends and family unit members, nosotros asked testers to rank unmarked samples for qualities like "dirty," "refreshing," "artificial" and "crisp."

After running two dissimilar groups, the results were all the same tricky to draw conclusions from. Simply when we ran a 3rd test with controls for what our judges drank at home, preferences lined upward into categories: Filters that utilize by and large granular carbon (like Brita and PUR) were definitely more than popular with people who drink tap water or spring water, and the mineral-free sense of taste of ZeroWater is a clear winner with those who are used to a reverse-osmosis systems.

Results take shifted over the years for the tiptop rank inside the carbon filter group, just the important choice is definitely between leaving minerals in or taking them out.

Comparing these filter categories to bottled water brands, Evian and Arrowhead match the minor mineral levels of our tap water at 300–400 parts per meg. (Perrier and Gerolsteiner are two or three times higher.) At that place are also bottled products that become through opposite-osmosis treatment to get virtually-goose egg levels of dissolved solids, similar Dasani and Aquafina. Almost bottled water sits somewhere in the middle, at betwixt l and 150 ppm.

Water filter speed

We too tested each filter to determine how long it would take, on average, to filter one cup of water. While you might non be worried about this result, it'due south worth considering how long it takes to get more filtered h2o if you're ever going to fill bottles before a trip or serve water at a party.

For this test, the standard Brita filter is a winner at only xl seconds on average to filter one cup of water. The slowest water filter in our tests used to be the ZeroWater filter, which took an average of 110 seconds to filter 1 cup of exceptionally-clean water.

When we switched to the lead-reducing versions of Brita Longlast and PUR filter, though, information technology was clear that their improved performance over standard carbon filters is related to the speed water is allowed to trickle through. They take about five times longer than the non-atomic number 82-filtering Brita, even longer than the ZeroWater.

With the fluoride-capturing Clearly Filtered pitcher, longer filter times are important to operation equally well. Only in this case it's almost unbelievably dull — over twelve minutes to filter ane cup with a barely used filter.

Ergonomics

Our tests didn't end with the filters. Nosotros too compared how well the pitchers piece of work for delivering drinking h2o to a waiting cup or bottle. About importantly, we looked to run across whether the pitcher was comfy to hold, even when information technology was completely full of water.

All the pitchers in our new lineup take features that allow you to cascade earlier the height reservoir is empty, though the Brita and PUR both take flip-open up filling ports you could use while holding the pitcher with simply i mitt.

None of these pitchers pour every bit well every bit we'd like. It's non exactly a trouble, but each bullpen has one ideal pour angle where the stream is controlled. That narrow stream gets wider and more than turbulent equally you increase or decrease the angle and period, so unexpected splashes are frequent until you learn just how to cascade.

Pitcher size

We switched our top performer, the ZeroWater, from a 10-loving cup to a 7-cup bullpen because smaller pitchers are slightly easier to handle. They're as well easier to fit in your fridge. With the smaller ZeroWater, you lose the direct-pour spout at the base of the bigger ZeroWater pitchers, but the catamenia from that spout is just a trickle. The PUR pitcher is available with the lead-removing filters in a smaller pitcher, merely Brita just sells the better filters with a 10-cup bullpen similar the round-base of operations Monterey.

Chlorine removal

We wanted to see how much difference filter blazon really makes with sense of taste'south biggest enemy, chlorine. So, we called in a Hatch chlorine test kit that can observe a .01 office-per-million (ppm) difference in total chlorine.

The tap water nosotros tested had between 0.seven and 1 ppm of chlorine beyond our tests over i year. We establish that whatever filter nosotros tried in our pitchers, no thing how long it had been in use, would remove all detectable traces of chlorine. The biggest changes in h2o gustation are the easiest to make, so a budget-class Brita filter replacement from the hardware store isn't actually a bad buy if that'south all you demand. But if you're worried well-nigh lead or other contaminants, or if y'all want a mineral-free taste profile, you'll need i of these more expensive options.

Filter life

Filter life is the trickiest factor to charge per unit. The water filters we tested all rely on capturing particles or attracting them to an activated medium, and that means they have a limited life. Dissimilar a ceramic or mesh filter that simply clogs up and doesn't pass water anymore when information technology's muddy, these activated filters volition just become less and less constructive over time as the contaminants build up and the water merely flows by. If you let them go long enough, bacteria or mold tin can even start growing inside these filters.

Brita rates their standard filter for twoscore gallons, and the new Longlast Filter at 120 gallons. That's compared to our tested boilerplate of 15 gallons for a ZeroWater filter earlier it becomes ineffective.

Those "average" numbers are assuming a lot, though. If you've got more than 400 ppm of dissolved solids in your water, ZeroWater cartridges might need replacing after just 10 gallons. At almost $10 per filter, a h2o softener and reverse-osmosis system showtime looking more than reasonable if you're filtering more than a gallon per twenty-four hours of something similar mineral-rich well water.

Longest Filter Life: Brita - Longlast

Brita'due south new filter lasts for 120 gallons, so it's much less expensive in the long run than whatsoever other arrangement nosotros've tested.

In contrast, the Brita filter is doing insufficiently piddling to filter minerals, and then it lasts longer. We watched the readings from a new Longlast filter for a few weeks, and after virtually 10 gallons the 20% comeback information technology showed over a standard Brita filter disappeared. You might get better-tasting water for 120 gallons, but after a month nosotros wonder how much the filter is still doing.

If you're going to be diligent virtually replacing filters, the ZeroWater system is meliorate at letting you know what's going on. You can cheque periodically with the included tester and see when the total dissolved solids climbs upwards from zilch to half dozen ppm, and supplant the filter before information technology stops working altogether. When the filter media is saturated with metal ions, it really starts to release some back into the water, and you'll immediately notice a sour or fishy taste. In comparison, you never really know when a Brita filter has lost its effectiveness.

Do you really need a h2o filter pitcher?

The benefit of filtered water is primarily taste. Fifty-fifty the most harmless particles tin add undesirable flavors, so whether y'all're drinking water by itself, making coffee or brewing tea a filter pitcher will help.

Water treatment makes sure most of u.s.a. in the Us take admission to clean h2o. Some people have a private well that they demand to monitor themselves, merely the vast bulk of the states rely on a local h2o authorization. Many of those offices will mail a consumer confidence report straight to yous, or you tin can find information technology through the Environmental Protection Agency database. This shows how close household water is to the goals set by policy-makers. They'll also report on secondary standards, water-quality factors that affect gustation, color and hardness.

When reading a consumer confidence report, if you see a listed contaminant that'southward besides close to the limit for comfort, yous can bank check for that contaminant on filter ratings before yous buy.

Please notation: None of the water filters we tested is certified to remove biological contamination. If you go a "boil h2o informational" for your area, you should boil your h2o for i minute (and let information technology cool) fifty-fifty if yous run information technology through a top-rated filter organization to improve the sense of taste.

Chlorine and taste

The master reason to filter drinking water is that chlorine and chloramine — the disinfectants used in most civic water supplies — taste awful. The amount is depression, only y'all can make nearly tap water taste better by filtering information technology. This is all covered in NSF standard 42, which is the well-nigh common certification for consumer water filters.

When we tested with brand-new and well-used water-pitcher filters, nosotros found that carbon filters are very constructive at removing chlorine for long past their rated life.

What nearly lead pipes?

H2o in our tester'south metropolis is pb-costless at the source, only the consumer conviction study from the local water authority says that over ninety% of the homes they tested have old pipes that add together trace amounts of atomic number 82 to tap water. It's about one tertiary of the allowable level of lead but well in a higher place the public health goal.

This is a like situation to homes in Flint, Michigan in the decades before the Flint water crunch. Those pipes were also considered safety, until a new water source corroded the protective mineral layer that was keeping the lead under control.

In response to the Flint crisis, lead filtration has become i of the near heavily-advertised features of h2o filters — for example, PUR has an upgraded version of their filters with lead reduction every bit the simply distinction. All of the filtration systems nosotros recommend are specifically tested to remove lead.

Filter testing certifications

NSF International works with many food, health and safety agencies worldwide as a individual certification agency. Along with other standard-setters similar with the American National Standards Institute (ANSI) and the product manufacturers, NSF establishes what's expected from a water filter, then they (or an approved partner like the Water Quality Clan) exam and certify products.

NSF isn't an agency that recommends products, though — they merely examination and certify passing results or approve tests from a few other labs similar the Water Quality Association. These are the standard test groups for certified h2o filters:

NSF/ANSI standard 42 certifies that a h2o filter can better taste and odor. It's an piece of cake standard to run into with activated carbon and is the nigh common certification.
Class I Particle Filtration is typically included in standard 42 and ways a filter volition capture particles downwardly to one-half a micron in size. That covers most microplastics likewise every bit sediment.
NSF/ANSI standard 53 is the other mutual test group, and in this instance it certifies that a filter can reduce levels of specific contaminants in water from unsafe to rubber. Most filters have some NSF 53 certifications, though non all are certified for the same contaminants; it'southward important to note that the manufacturer chooses what to test for and advertise.
NSF/ANSI standard 53 — VOC is a subset of the safe test that covers volatile organic compounds ("VOCs"). Some VOCs, such every bit benzene, are easier to capture and can be tested individually. If a carbon filter is actress-effective — like the faucet-mountain filters we've reviewed — manufacturers can choose a test with chloroform, which stands in for all the trickiest VOCs.
NSF/ANSI standard 401 specifically covers xv contaminants that aren't yet regulated by health or h2o quality agencies. These include pesticides, flame retardants, detergents and pharmaceuticals. Merely 2 of the brands nosotros tested have been certified with any of these tests, and they each picked different compounds.

How many certifications is enough?

Comparing results for the unlike tests is tricky. "More than certifications" sounds like a sure advantage, but remember that these are chosen by the manufacturers, and they only tell you about tests they pass.

An example of this complication: PUR has a comparing folio showing their filters certified for removal of the VOC solvents benzene, carbon tetrachloride and tetrachloroethylene, along with iii popular weed killers, while Brita's Longlast filter is only certified in these categories for removing benzene. Both brands picked iii pharmaceutical compounds but not the same 3.

Does the longer list hateful the PUR is a better filter? No. According to standard carbon filter performance charts, these VOC compounds and herbicides are all expected to be captured in about the aforementioned fashion (a high or very loftier probability of being absorbed) by activated carbon.

Passing an NSF exam requires that the performance stay consistent for iii times the rated life of a cartridge, so information technology'southward too possible that Brita'southward narrower selection of compounds has more than to exercise with the rating on how long you lot tin can use their filter — 120 gallons instead of forty — and maybe Brita could have fabricated the same claims if they'd chosen a shorter filter life rating.

Nosotros wrote to Rick Andrew of the Global H2o Systems role at NSF International about the ways different tests are labelled, request if different VOC listings can be considered equivalent. He noted that there are two levels of testing for VOCs: I test uses chloroform as a "surrogate" compound to stand in for all the rest, but private compounds tin as well exist selected for testing.

Rick notes that most filters are just tested for the volatile chemicals that are easier to grab: "The VOC surrogate test can be difficult to pass — this is intentional. So, at that place are individual contaminant reduction claims tests specified in NSF/ANSI 53. Filtration systems may meet these requirements, however may not laissez passer the VOC surrogate test."

If you lot're looking for more-consummate filtering of organic chemicals similar industrial by-products, our picks for faucet-mount water filters pass the well-nigh difficult VOC examination. You tin search NSF and WQA databases just in example someone has specifically tested for the chemical compound you're worried near, simply that's a frustrating process. The lead-removing filter pitchers are each grabbing some VOCs, merely neither brand is a clear leader.

Can a pitcher filter remove fluoride?

Fluoride in water is a touchy subject. Studies continue to show that information technology tin can assistance showtime the take a chance of tooth decay in the people who are most at run a risk. But most of us who brush with fluoride toothpaste don't need the fluoride in our water.

Setting aside the contend, if you want to remove fluoride from your water, what are the options?

Deionized water, as you get with a ZeroWater filter pitcher, is ane pick. These filters remove nearly everything from water for as long as the expensive ion-exchange media is still working.

A reverse-osmosis arrangement will also remove everything, with a bigger up-front end cost and some wasted water, but a long-term cost savings over ion-substitution filters. Distillation gives similar results, though it'southward slow and has loftier energy costs.

A specialized alumina filter can as well work, as seen in community water projects in India that remove excessive naturally-occurring fluoride. There are at present filter pitchers that apply alumina, simply they're very slow — the Clearly Filtered alumina filter takes more than than 10 minutes to filter one cup of water. The Berkey countertop water system is also bachelor with a similar slow-acting alumina filter.

Thus far, NSF international has only tested and certified contrary-osmosis or distillation systems for fluoride removal.

The bottom line

If you lot're looking for h2o that is equally pure as possible, and completely free of all dissolved solids (both benign and harmful), the ZeroWater filter is a corking option; however y'all could air current upwards paying every bit much as bottled water costs for the filters.

Ultimately, any of the water filters we tested will easily improve the gustatory modality by removing chlorine. Brita'southward Longlast filter is by far the nearly cost effective, lasting iii times more water than near of the other brands and removing more than heavy metals than the basic Brita.

Our Superlative Pick: Brita - Monterey

Brita'south new filter does everything most people need, and it lasts a long time. The 10-cup pitcher is attractive and works well for serving water at parties.
