Brita vs. PUR — is your glass half empty or half full?

This review aims to splash some water on the truth behind which water filter is best.

PUR vs. Brita comparison

We’ll look at the overall design, filter efficiency, speed of filtration, water taste, and common questions about the products.

Which water filter is best for you? PUR or Brita?

Find out now!

PUR vs. Brita – What’s the Difference?

The PUR filter removes more contaminants compared to the Brita filter. However, during our taste tests and TDS tests Brita performed notably better. Both Brita PUR offer a variety of pitcher sizes and types. If you have a wider range of contaminants you need to remove PUR is the better choice, but for most consumers, Brita is better.

PUR vs. Brita Comparison Chart

In the following table, we take a high-level look at the primary differences and similarities between the PUR and Brita pitcher filters.

Brita Everyday
  • TDS: 396 ppm
  • Filling Tank Capacity: 5.7 cups
  • Filter Speed: 1.05 cups / min
  • Taste Test: 83%
  • Price: $
PUR Basic
  • TDS : 511 ppm
  • Filling Tank Capacity: 3.8 cups
  • Filter Speed: 0.80 cups / min
  • Taste Test: 69%
  • Price: $

For the specs above, we compared just a single model for each Brita and PUR, however, you should note that there are a variety of pitcher types, varying in size and form factor.

You can see more PUR pitcher types here and more Brita pitcher types here.

In our recent ZeroWater vs. Brita vs. PUR comparison we test larger reservoir types for Zero and Brita.

Filtration speed is based on the Brita Everyday and PUR Basic models. For both, we filled them to their respective reservoir capacity and then timed them accordingly.

Lastly, TDS and taste tests are based on our in-house tests. Jump down the page to see more on our tests.

Prefer to watch rather than read? We’ve got our PUR vs. Brita video below:

A Quick Intro

Brita vs. PUR water filters—both names are well known, but is one definitively better than the other?

In their most basic form, water filtration pitchers are designed to remove contaminants from your drinking water, for a pure, crisp taste, that saves money from being wasted on bottled water.

This review is going to take a closer look at two of the most popular filters on the market: PUR vs. Brita.

Brita vs. PUR Design Differences

Both Brita and PUR have a few different models of water filters to choose from.

For the sake of this review, we’re going to specifically be comparing the Brita 10 Cup Everyday Water Pitcher and the PUR 7 Cup Water Pitcher. From aesthetics alone, Brita and PUR look similar.

Both pitchers use a similar design. You fill water into the top reservoir, it filters through a single filter (composed of activated carbon and ion exchange resin) and that water deposits into the base of the pitcher.

When it’s time to drink, the water from the base travels up the pitcher and out the spout.

Additionally, both pitchers have an easy-pour spout and a comfort grip handle.

There are two main design differences between these two models: the filling method and the water capacity.

  1. FILLING METHOD | The PUR water filter pitcher has an easy-fill top that allows you to fill through the top of the pitcher without removing the entirety of the lid. The Brita water filter pitcher doesn’t have the easy-fill lid, so you will have to remove the entire top lid to fill it.
  2. WATER CAPACITY | The second difference is the overall capacity. The Brita pitcher can hold up to 10 cups while the PUR filter can only hold 7 cups.

That said, both of these issues are fairly fluid, as there are some Brita water filters that do have the quick flip top, just as there are some PUR pitchers that don’t.

In addition, there are Brita and PUR filters of all sizes, from 5 cups all the way up to 40 cups. See more Brita models here and more PUR models here.

How Do Brita & PUR Filters Clean Water?

As mentioned above, both water filters rely on a single standalone filter that’s made of activated carbon and ion exchange resin.

Brita standard filter

The activated carbon reduces chlorine (taste and odor) and mercury, which improves the taste and odor of the water. The Ion-Exchange Resin captures copper, cadmium, and zinc in the water.

Brita Filters

Brita offers two main filters for pitchers, the “Standard” filter and the “Longlast” filter. Both filters are compatible with the vast majority of Brita pitchers (only the Brita Stream and Brita Infinity use different filters).

The “Longlast” is supposed to last about 3 times longer than the standard filter, but is also more expensive.

The Standard filter can be replaced fairly inexpensive when purchased in bulk, like this set of six Brita filters. Alternatively you’ll pay a bit more when you buy single Brita filter replacements. Both filters are BPA (bisphenol A) free, but there are considerable differences in the contaminants that each filter purifies.

The LongLast filter does last longer, but it’s also significantly more expensive.

If you don’t really care about using Brita filters for your Brita pitcher, AmazonBasics offers generic filters for even less.

PUR Filters

PUR also offers two styles of pitcher filters: Basic and Lead Reduction.

As the name sounds, the Lead Reduction filter removes most everything the Basic filter does and also filters out lead. The Lead Reduction filter cannot filter out the herbicide Linuron, select industrial pollutants, and pharmaceuticals.

Brita vs. PUR Filter Comparision

The table below breaks down exactly which impurities will be filtered out by each filter if you’re concerned about a specific contaminant.

Reminder: It’s also important to note that neither brand claims to be able to filter anything beyond city tap water (for instance, country well water or water straight from a natural source, like a pond or stream).

Contaminant Brita Longlast FilterBrita Standard FilterPUR Lead Reduction FilterPUR Standard Filter
Chlorine (Taste and Odor)YesYesYesYes
Particulates (Class I)YesNoYesYes
Industrial PollutantsNoNoNoNo
Carbon TetrachlorideNoNoYesYes
Bisphenol ANoNoYesYes
Cyst (Parasites)NoNoYesYes
Nominal ParticulateNoNoYesYes

Both Brita and PUR standard water filters (like the styles listed above) are designed to reduce the following contaminants:

  1. Chlorine (taste & odor)
  2. Mercury
  3. Cadmium
  4. Copper
  5. Zinc

In addition, PUR filters are designed to reduce the following contaminants (in addition to those listed above):

  1. Herbicides, including 2, 4-D, Atrazine, Linuron
  2. Industrial pollutants, including Benzene, Carbon Tetrachloride, Tetrachloroethylene, Bisphenol A, Nonylphenol, TCEP. Keep in mind that, the standard Brita filter cannot filter out Benzene (a common chemical used in the US and known to be a human carcinogen) , but the standard PUR filter can. To filter Benzene with a Brita system, you’d need to purchase the “Longlast” filter.
  3. Parasites, including Cyst
  4. Pharmaceuticals, including Atenolol, Carbamazepine, and Estrone
  5. Sediments, including Nominal Particulate, Class I

Standard Brita filters list no information on their effectiveness to filter out herbicides, industrial pollutants, select pharmaceuticals or sediments.

More advanced filters by each company can filter out, even more, contaminates, like Lead and Asbestos.

  • For Brita, this means going with the “LongLast” filter.
  • For PUR, this would mean the Lead Reduction filter.

Brita vs. PUR: The Tests

To evaluate the performance of each water filter, we look at two different factors:

  1. TDS (objective numbers)
  2. Taste (subjective opinion)

The TDS test is “total dissolved solids“, which basically accounts for anything in the water that is anything but pure water. Generally speaking, the higher the number, the less pure the water is.

TDS meter (total dissolved solids)
TDS meter (total dissolved solids)

The taste test was a test with a small group of individuals who blindly tested Brita water and PUR water and scored them on a 1-5 scale according to taste preference.

The TDS Test

To perform our TDS test, we use a TDS meter, which measures the number of “total dissolved solids” in the water.

Brita water filter

Generally, a high number means less pure water, but those assumptions do come with a few caveats. Naturally occurring (and healthy) minerals in water can add to the TDS number. Similarly, the salinity in water (as is the case with softened water), can also increase the TDS number.

TDS Before & After Data

With that in mind, here were our findings:

NOTE: PPM stands for “parts per million”


Manufacturer filter

  • Unfiltered: 542 ppm
  • 1st Pour: 530 ppm
  • 2nd Pour: 555 ppm
  • 3rd Pour: 511 ppm

PUR (3rd party)

Aquacrest filter

  • Unfiltered: 542 ppm
  • 1st Pour: 509 ppm
  • 2nd Pour: 498 ppm
  • 3rd Pour: 405 ppm


Manufacturer filter

  • Unfiltered: 542 ppm
  • 1st Pour: 495 ppm
  • 2nd Pour: 428 ppm
  • 3rd Pour: 396 ppm

During our PUR vs. Brita tests in 2019 we noticed taste improved dramatically as more water was flushed through the filter. In line with this thinking, we expected TDS to improve as more water flushed through also.

ZeroWater taste test
Dramatic action shots of the taste test

The above 1st, 2nd, and 3rd pour represent our different levels of filter flushing.

  • 1st Pour – no flushing, we simply installed the filter, filled the resevoir, let it filter, and then made our test
  • 2nd Pour – we filled the resevoir a few times to give it a light to moderate flushing and then tested the water
  • 3rd Pour – we filled the resevoir several times, running a couple gallons of water through the filter before testing the water

In all cases, the TDS did improve as we flushed each filter, with Brita and the 3rd party PUR filter being the most dramatic difference between 1st and 3rd pour tests.

The PUR manufacturer’s filter did not dramatically improve as we flushed water through it.

Does Brita or PUR Filtered Water Taste Better?

Water taste by both the Brita and PUR water filters may vary based on the quality of the water that is filtered. As mentioned earlier, neither filter is intended to be used with well water, rural water, or any other water source besides city tap (or comparable) water.

PUR vs. Brita

Both water filters are designed to reduce chlorination in the water, which in turn improves the taste and removes any chemical odor from the water.

Of course, all of these facts are based on what each manufacturer states to be true about its pitcher. But the real question—how does it REALLY taste? This answer can only be found through tasting water processed by each filter.

Brita vs. PUR Taste Test

Our taste tests confirmed that Brita is the best tasting filtered water, scoring 83% out of 100%. PUR is 2nd place, at a 69%. This taste test was a follow up to our original tests in 2019, which also had Brita as the preferred water based on test.







Our taste test was conducted with a small group of my personal friends. I asked family and friends to try different cups of water and rate them on a 1 to 5 scale, where 5 is the best.

Brita vs. Pur scoring
We scored our test taste on a 1-5 scale.

Each cup of water was poured into a paper Dixie cup and unmarked (except for a notation on the bottom of the cup so I could tell which was which when compiling the data).

PUR vs. Brita taste test
Cups were marked 1, 2, or 3, so the experimenter (me) could keep track without creating experimental bias.

WATER & LOCATION | Our test took place in Phoenix, Arizona using normal Phoenix tap water. Water in this region is incredibly hard. My home does use a water softener system, but no other RO or other water purification systems.

TEST PARTICIPANTS | All participants were adult volunteers. Ages ranged from 22-65.

Issues with the PUR Filter

During our initial test, we noted that the PUR filter was scoring dramatically worse compared to Brita. Scores during the initial test were as follows:







THE PROBLEM | Despite the fact that we followed PUR’s setup instructions exactly, there was a clear and distinct metallic taste on the filtered PUR water. This taste was only present on the PUR filtered water and not the tap water.

A dramatic reenactment of the taste test

POSSIBLE CAUSE | This seemed incredibly weird to me, so I thought we might have a faulty filter (which actually may have been the case). However, before ordering a new filter I decided to run around 5 gallons of water through the PUR filter, to see if perhaps it just needed further flushing.

RESOLUTION | After doing so, we retested the three filters with additional test volunteers to see if the results were different, which they were. We felt like the second set of testing data (which is what we have up top) was more accurate. Nevertheless, we did think it was still important to point out the difficulties we experienced with getting the PUR filter to an acceptable taste.

Are Brita and PUR Filters Interchangeable?

FAQ: One frequently asked question by consumers is whether or not these filters are interchangeable. While both filters look strikingly similar and do use the same design for water filtration, these filters are not interchangeable.

Subtle differences in product design help to ensure that each product can only be used with its associated, branded filter.

If you like your water pitcher, but are unsatisfied with the filtration, you may want to consider upgrading filters.

As mentioned above, the Brita system works with the Standard Filter or the Longlast filter. Likewise, the PUR system works with the Basic Filter or the Lead Reduction Filter.

Brita Faucet vs. PUR Faucet Filters

For some, filling and pouring the pitcher can get old and become a tedious chore. For filtered water without the hassle of pouring and storing in another container, both Brita and PUR also offer faucet version of their popular filters.

30-Second Summary

Here is a quick 30-second summary of Brita vs. PUR faucet filter systems.

Brita & PUR Faucet Filter Designs

The design is extremely similar between the two; both screw directly onto the faucet and filters the tap water through the system and out a secondary water spout. The filter size of each unit is similar, but the orientation is different.

The Brita has the main filter positioned in a vertical position, while the PUR filter is oriented horizontally (in most cases).

Installing Brita on tap faucet filter
Faucet filters attach directly to your kitchen faucet.

That said, if you prefer the vertical filter, PUR does offer that option on several models as well.

Perhaps the biggest thing to note is that Brita and PUR faucet filters only work on standard faucet heads. If you have a pull-out, spray, large or oddly shaped faucet, the Brita and PUR faucet filters probably will not fit.

What Contaminants Do the Brita & PUR On-Tap Filters Remove?

BRITA FILTERS | The Brita faucet filter can remove 99% of lead, and reduce chlorine (taste and odor) and remove 52 other contaminants. See the full list of removed contaminants here. 

PUR FILTERS | By comparison, PUR’s faucet filter is certified to reduce over 80 contaminates, which also includes 99% of lead. See the full list of removed contaminants here. 

If lead is an important contaminant to address, I would recommend the faucet filters over the pitcher filters (unless you upgrade to the PUR Lead Reduction filter or Brita Long Last filter).

Brita On-Tap Filter Finishes

The Brita Faucet filter is available in both a chrome and white finish.

PUR Faucet Finishes

If you’re looking for more color options that coordinate with your existing kitchen faucet, PUR’s faucet filter is available in black, chrome, metallic gray, stainless steel, or white.

Brita & PUR Smart Water Filters

The PUR Ultimate Faucet System comes equipped with Bluetooth capabilities which allow the filters to pair with the PUR app on your smartphone and track water consumption, filter usage, and other features.

At the time of publishing this guide, Brita did not offer a smart on-tap filter.

However, it does offer the Brita Infinity wifi-connected pitcher. This filter can be set to automatically order replacement filters from Amazon when it detects the filter needs to be replaced.

It’s not quite as advanced as the PUR Ultimate Faucet, but it’s still pretty cool!

How Long Do Brita & PUR Filters Last?

The Brita Faucet Filter can filter about 100 gallons of water (approxiamtely 4 months of daily usage) before the filter will need to be replaced. When it’s time to replace, both faucet filters have a light that will flash to notify you.

Should You Buy the Brita or PUR?

So, all things considered—should you buy the Brita or the PUR water filtration pitcher? I would call this battle of the bottles a draw, simply because there are pros or cons to each model.

One may certainly be better for you, but what works for you could be less than ideal for someone else.

The points below will highlight some of the most important buying factors, in our opinion.

Buy Brita if…

I would recommend the Brita Water Pitcher to people who:

  • Want to spend less money on filters – At the time of our review, Brita filters generally seemed to be less expensive than PUR filters. Additionally, you have the option of buying Amazon’s generic Brita filters for even less if you want to save more in the long run.
  • Want better tasting water – During both our 2019 and 2020 taste test, the Brita filtered water tasted better. Of course, with that said, our sample sizes were fairly small. Nevertheless, our testers scores had a small deviation. Additionally, local water sources will change the taste. However, during our tests of Phoenix, Arizona water, Brita was the clear winner in taste.

To learn more or to buy, see Brita’s water filters here.

Buy PUR if…

I would recommend the PUR Water Pitcher to people who:

  • Want a pitcher that removes more stuff – According to the company’s specs, the PUR filters are able to remove a much wider array of contaminants compared to Brita. If you’re worried about the health and safety of your tap water, the PUR may be a better choice due to this reason.

To learn more or to buy, see PUR’s water filters here.


  • June 11, 2020 – Re-did our taste test with updated filters for Brita, PUR, and a 3rd party PUR filter. We had to do a taste test for a different water filter, so we decided to do PUR and Brita at the same time to ensure accuracy with current market filters. Also added TDS (total dissolved solid) tests and analysis. Reviewed all article contents to ensure accuracy, making minor updates.
  • April 16, 2019 – Improved layout and formatting of a couple of sections.
  • March 14, 2019 – Overhauled page template and design.

51 Comments on “PUR vs. Brita”

  1. Hi, and thank you for this article.

    I’m rather puzzled. Wouldn’t you want the filter that filter out the most substances. I read an article that said while our tap water meets government standards, those standards were set many years ago. And, just because the water meets those standards, that doesn’t mean our water is healthy. It had been speaking about filters that probably took almost everything that “could” occur in tap water. This last part made decide to eliminate getting a Brita bottle or pitcher. Think I was last looking at the Nalgene because it too takes out a lot. And should I travel or be where there is no tap water for an extended period of time, they also carry an outdoor filter that also fits the same bottle. I also read in another article that some tap water contains substances that are cancer causing and some good be detrimental to a small child. Several articles discouraged Brita because it is vague in speaking about how good the filter is or what it removes. In fact, it only says it reduces so that could be very little and still be able to say it, and they do not list the other stuff they remove, saying “and more” or “much more.” If they did a good job, they certainly would say, especially because to be copetitive, they have to because other personal bottle companies are begin to give a lot of detail as to the ALL the contaminants, etc. they remove. What do you think?

    • Lots of good questions here, questions I had myself about 18 months after we did this initial comparison.

      So I got 10 water pitchers and sent them to a laboratory for testing.

      This page has all of those laboratory findings –

      Summary, both Brita and PUR are fine, but not the best. A filter called Waterdrop was #1, closely followed by Epic Water.

  2. The Zero pitcher filter lasted maybe a week week with our Arizona water , which registers about 624. How long will a faucet PUR filter last?

    • That’s pretty high usage. I too use Zero in Arizona and tend to get around 3-4 weeks (PPMs in around 550 with the Phoenix tap water).

      PUR filter will definitely last longer, perhaps 6-8 weeks depending on usage. However, it won’t remove much of what Zero was removing.

  3. I’m concerned with the Brita. Have been using it for a year and when it sits for a while there are black particles that I presume comes from the filter. In your tests did you let the filtered water sit for say a day and note the difference of what if any particles settle?

    I also after a while see other floating particles. I use the basic filter.

    Interested in your thoughts.

    • Yes, those are pieces of the carbon particles from the filter. Some filters will let more of those out, and others won’t. Seeing those is pretty typical with most carbon based type filters.

      We’ve been using the Brita in our studio for many months. We don’t drink often out of it, so it’s been the same filter for several months.

      If you’re seeing more of those black pieces I would suggest just getting a new filter.

  4. BTW: Have you done a cost of ownership between the two products? For example, after 12mos, the cost of filter replacement etc…

    • Nothing formal, no.

      But it should be more or less the same. Both Brita and PUR are available in a variety of form factors as far as the pitcher / tank goes, with prices ranging from $20 to $40.

      And both filters are around $5 per and filter for around 40 gallons.

  5. I would also mention recycle options for both filters. I think Brita is better in recycling program. I have Pur, and when I went to “recyclenation” locations it doesn’t give me any option to drop-off filters. And there is no option to mail Pur filters.

    • I’m fairly sure it’s just a timer sensor, Ron. It measures how much time it has been since you clicked the reset button.

  6. Thanks for the comparison. Previously PUR had just one kind of filter, and that was their claim to fame in comparison to Brita.
    It used to remove lead among other things, now they have two kinds, one removes lead and the other does not. So much for their advancement in technology.

    • Interesting. I didn’t realize that.

      That does indeed dispel some of the marketing mystique about PUR. Sad to see it.

  7. I am really upset because the Brita water faucet filtration system is giving me trouble prior to, and after installing my first replacement filter. Turning the switch manually to the filtered, or unfiltered position is proving to be difficult, and water is coming out of both conduits. I’ve had similar issues with the PUR brand water faucet filtration system, and it seems that neither unit will last more than 2 to 3 filters until you are forced to buy a new one. Submitted for your consideration.


    Francisco Lopez

    • Hrm…that is indeed a serious problem. I’m sorry to hear about your trouble with it.

      I would suggest you reach out Brita (and maybe PUR too), certainly that experience isn’t ideal. I wonder if their support team would have a suggestion on how to fix it…or at the very least may be able to send you a replacement unit.

      You can find Brita’s support here –

  8. I purchased a PUR chrome faucet mount pure filter, when the time came to replace the filter I found it IMPOSSIBLE to do so. I purchased a second PUR faucet mount filter and had the same problem. If anybody has any suggestions as to how you install a new filter in the PUR faucet mount unit, I would appreciate any help or advice. Thank you

  9. I just moved to Phoenix and am looking at getting a water filter. Since you live here, I figured you’re the person to ask. I bought the Brita 18 cup longlast pitcher, but I haven’t used it yet. I feel like the faucet filter would be more convenient, so I was gonna get one and test it. Which brand/model/type would you recommend for the Phoenix area?

    • Either Brita or PUR will be fine for Phoenix. I’ve used them both extensively over a period of many months and in the long run found both of them to be about the same.

      The biggest problem with Phoenix water is it’s incredibly hard. If you’re able to get a water softener system for your home or even just for your primary drinking water under your sink that will make a much bigger difference.

      Not only does it make a difference to your drinking water, but it helps your appliances last longer, avoid build on up sinks, and makes your showers more enjoyable.

      Best case scenario…water softener + Brita or PUR
      Okay case…Brita or PUR
      Worst case…water straight from the tap

  10. Our Brits filter has started making a vibrating sound when the water is turned up. The water has also stopped running when on the filter side. It will start again if you wait. I took the filter off and the spigots run normal. We just tried two new filters for the brita.

    • Unfortunately, that is beyond our expertise to diagnose that problem.

      You should reach out to Brita’s customer support here – 1 (800) 242-7482

  11. On you put in your zip code and it tells you what contaminants they detected in your water.
    I was totally shocked to see a list of 31 contaminants in my tap water.
    Now on a search for a simple water pitcher that has a filter that would remove or reduce most contaminants.
    Very confusing on choosing the best water filter.
    Zero / Pur / Brita LongLast / Aquagear to name a few.
    Would like to see a total read out of each on what the filters reduce in contaminants.
    Can you recommend one?
    Thanks in advance.

    • If you scroll about halfway down the page you’ll see a table that lists what both Brita and PUR filters remove in terms of contaminants.

      Honestly, both Brita and PUR (and probably Zero) are good filters. They will all reduce the majority of the worst contaminants from your water. Both are good values for what they accomplish.

      If you still find that it’s not enough you may want to look into an reverse osmosis (RO) system. This is the same type of filtration that Dasani and other bottled water companies. So that’s something to consider also.

  12. bought brita faucet filters and after 2 to 3 weeks use feom a strong output of filtered water then it just trickles until it jist drips

    is this normal when its suppose to lastnlonger, have replaced 3 timea and the outcome is the same let me know what yo do

    • That certainly does not sound like normal behavior. A typical filter should last a couple months, at least (though it does depend on use).

      I would suggest you reach out to Brita support here – – they are going to be able to offer you better advice given you situation.

  13. The section “Issues with the PUR Filter” looks confusing. Did you mean you had never got it working properly until you filtered a 5 gallons of water using that filter?
    Also, when you referred to more tests with additional volunteers, it would have been easier if you had mentioned how many filters you had tested and how many gallons you had filtered before the actual taste and was the same repeated exactly for both brands etc.,

    • To clarify:

      The PUR was working and filtering water from the beginning. However, initially it had more of a metallic taste. Once we had run a sufficient volume of water thru the filter it lost the metallic taste.

      Regarding the additional taste testers. For our initial taste test we set them up based on our their respective instructions. It was clear from our initial test the the PUR had a notable metallic taste that many disliked (hence the poor rating). We ran a second taste test with the PUR where we ran several gallons thru it to help further flush it out before the test began. That did seem to work, as the second round of taste testers rated it much closer to the Brita in terms of taste.

      We tested a single filter for each brand. It’s possible it was a single bad filter, which is why we thought it prudent to run more water thru it to help flush it.

      Let me know if you have any other questions.

  14. A puzzlement here…

    The comparison table first states “NO” for Particulates (Class I) for the Pur filters. Then the table says “YES” for Nominal Particulates for the Pur filters, further explaining in “In addition, PUR filters are designed to reduce the following contaminants (in addition to those listed above):” that such “following contaminants” include “Sediments, including Nominal Particulate, Class I.”

    Is “Nominal Particulates” include or exclude “Particulates (Class 1)”?

    Please clarify.

    • Thanks for bringing this question to our attention, Lawrence.

      We either made a mistake or PUR has updated their specs since our original review.

      In any case, all PUR filters are able to remove Class I particulates based on their most recent spec sheet. We’ve updated the table.

    • I think that’s a good idea.

      We’re not water quality experts, but from everything we’ve read it would seem there might be algae in the water itself.

      You might try just putting a bit of water in a glass jar and leaving it for a couple of weeks to see if you get the same issue.

  15. I live in CT and changed to Brita from Pur when I needed a new container. Never had the green deposit on bottom of the pitcher until I used Brita. This time replaced filter and within 10 days the green was on bottom and one side. What is happening?

    • What is your water source? Local city water? Well water? Or something else?

      Water source is normally the biggest factor.

      What it sounds like is you have algae in the water source. I’m surprised you weren’t experiencing it with PUR also, as the filters are functionally very similar.

  16. I have been using Pur filter for decades now. We now own two of them since I find the smaller size more convenient. A few years ago I had problems with the filter slowing; company said to pull it out, shake it and re-rinse. Solved the problem. Seemed to have been a problem in the production run (which they didn’t admit), since when we ran through our stock on had and replaced we haven’t had any more problems.

    • Thanks so much for sharing that tip, Diane! That’s great info.

      I’ll definitely give that a try if mine starts slowing.

  17. I second Tenzing Sherpa’s comment. I used a PUR filter and it slowed down a lot within a week, and was glacially slow after a month. I suspect that it was due to the fact that the water in my town is really hard. I just got a brita filter; I hope it will fare better

    • That’s interesting. I’ve been using the PUR for a few months for a longer-term test. I haven’t noticed it getting that slow (certainly, it’s not fast, but not terribly slow).

      We have pretty hard water here in Phoenix also.

      I would say it takes 3-4 minutes to filter a full reservoir of water when it’s empty.

    • Thanks for the suggestion, Sam. We’ll take a look at the Berkey filter and see if we can test it.

  18. What I’ve been having trouble with the Pur is, it’s slowing down significantly after a week’s usage. I live with 4 other roommates… and one filter is supposed to “last 4month” or rather “40 gallons”. That means.. in one weeks time period, we drank 40 gallons of water??
    This has happened to me 2 times already.
    I was hoping to get a suggestion on a most cost conservative filter than Pur’s 18cup.

    • Hrm…that is indeed very strange. It doesn’t seem likely that the filter would degrade that quickly. Though if this is your 2nd filter, that too seems weird that you’d see this issue back to back.

      Have you used other filters in the past?

    • I am facing same issues. Pur lead removal faucet filters last only 2 weeks. After one week flow rate slows down and by 13-14th day, it just completely die.

    • Can I ask what state you live in?

      I wonder if the total dissolved solid rating within your state could be accelerating the rate at which the PUR filter stops functioning.

  19. Hi Lisa,

    I’ve used the Pur water faucet filters (different designs also) for many years and they always spring a leak after a few years. Never fails. Still, it’s a simple system and the filters are carried by Costco so I go back to it.

    • True, they aren’t perfect systems. But at the end of the day, they are inexpensive (compared to other options) and widely available at lots of retailers. It’s really hard to go wrong with PUR or Brita.

  20. I’ve been using a Pur faucet filter system for a couple years, and had no problems, until it somehow started leaking, so I bought an identical replacement, and it also leaked, so I bought a different color replacement, and it also leaked. I’m going to try one more time because I already bought extra filters that I can’t return. Has anyone had issues like this with Pur, or with Brita?

    • Hey Lisa,

      I wonder if there is a compatibility problem with your faucet? 3 in a row, especially with new PUR faucets makes me think there might be a problem with your sink.

      When my wife I first moved in we experienced a leaking issue on our faucet simply due to the age and amount of hard water build up around the spout.

  21. The table in contaminants doesn’t seem to gel with the Pur website which shows that the lead reducing filters all the contaminants the standard filter does + lead.

    • Hi Josh,

      Thanks for bringing that to our attention. It looks like PUR may have updated their lead filter specs since we released this piece.

      We have updated the table to fix those errors.


  22. You didn’t mention that Brita leaves a deposit of tiny carbon granules on the water intake reservoir and on the top of the replaceable filter that is almost impossible to clean. However, these granules do not enter the bottom water filtered reservoir. Very nasty to see and try to clean off.

    • Hi Bill,

      I didn’t mention it because it was not something that we encountered with the Brita filter during our tests.

      We didn’t experience on PUR either.

      I have seen that problem on other filters / pitchers, but as you say, the granules don’t ever enter the filtered water…so for most I think it’s a non-issue.
