Do Brita Filters Remove Pfas
The safety of drinking water is a hot topic these days. PFAS chemicals, nearly notably PFOA and PFOS, have been linked to cancer and other diseases in humans. These chemicals are often establish in the tap water of many homes across the country considering they exercise not break downwards similar other contaminants.
If you're wondering if your Brita filter tin remove PFAS from your tap water, the answer is no. While activated carbon in a Brita pitcher can remove some of these contaminants from drinking water, information technology does not reduce their concentration to drinking water standards. Brita filters are not designed to treat PFAS and should NOT exist used for this purpose.
This commodity provides real world testing data for Brita filters in use at homes with PFAS contaminated drinking water. This data demonstrate that Brita filters merely remove some of the PFAS, just non all of information technology. We have data for other pitcher filters, besides.
Continue reading to acquire more about PFAS in drinking h2o and how well Brita and other pitcher filters perform.
Do Brita Filters Remove PFAS
Brita filters are non suitable for treating drinking water contaminated with PFAS. Brita designed their filters to remove things like chlorine, taste, lead, zinc, and other contaminants. Nonetheless, their filters are non designed to remove PFAS.
For this reason, you tin can NOT utilise a Brita filter to treat PFAS.
Exercise Brita filters remove any PFAS?
Brita Filters use activated carbon as a filter, so they remove some of the PFAS in water. Notwithstanding, they do NOT consistently remove all of the PFAS to drinking h2o standards. Pitcher filters similar Brita should non be used to treat PFAS for drinking purposes.
This statement is consistent with guidance offered by country health agencies, experts in the industry, and real earth testing of Brita filters. We obtained data from a Duke University study that tested Brita pour-through filters being used at houses that had PFAS in their drinking water. Duke's testing showed that Brita filters can reduce the concentration of PFAS in drinking water, only they practise not remove all of the contaminant.
More chiefly, they do non consistently reduce PFAS levels to below drinking water standards.
We present a summary of the Knuckles study, along with their data, later in this commodity.
Duke plant that pitcher filters remove almost 52% of PFAS from h2o. They also establish that the treatment efficiency varies substantially based on factors such as the PFAS concentration, the age of the filter, and water hardness.
For these reasons, you should not use a Brita filter to remove PFAS from your water. At that place are other, meliorate treatment methods that are effective and safe to employ.
What does Brita say almost PFAS
Brita filters not only cut chlorine taste and odor, only they reduce other contaminants as well. With their new Longlast+ Filter you can enjoy cleaner water with less take a chance of atomic number 82 contamination than when using any pour-through systems.
Brita's website says they remove the following contaminants from drinking water. As y'all can see, they don't mention PFAS or any other fluorinated compounds at all.
- Chlorine (sense of taste & odor)
- Lead
- Mercury
- Cadmium
- Benzene
- Asbestos
- Particulates
- Copper
- Zinc
- ane, two, 4 – Tricholorobenzene
- Select pharmaceuticals, pesticides/herbicides, TTHMs and Atrazine
- Additional contaminants
Brita makes a variety of bullpen filters that purify drinking water. They all use activated carbon to remove contaminants equally shown in the cutaway below.
These pour-through filters are referred to every bit indicate of employ (POU) devices because they provide treatment where the water is consumed. Point of use filters are a cracking fashion to treat drinking water because they're pocket-size and easy for the user to operate.
However, these systems do not provide a way to monitor how well they are performing and they must exist properly maintained to remain constructive.

Testing Your Drinking Water for PFAS
You can now test for 14 different PFAS compounds with the SimpleLab at-abode kit. It'southward easy to use and includes everything you need. They provide you with a comprehensive study that summarizes any PFAS compounds they observe in your water. They also explain what the results mean and whether you need to do anything to protect your family'southward health.
I used the SimpleLab kit to test the tap water at my business firm. Unfortunately, I have low levels of PFAS in my drinking water. Read my article about this examination kit and my feel with information technology.
PFAS Treatment Tests for Pitcher Filters
Duke Academy conducted a study of pitcher filters to see how well they remove PFAS from drinking water. Their report found that pour-through filters removed about l% of the PFAS compounds.
This study tested 13 filter units to see how well they performed at treating PFAS. The boilerplate PFAS removal efficiency for pitcher filters was 52%.
The lowest treatment efficiency for PFAS was 8.3%. The best PFAS removal was 99%.
At that place was too a difference in PFAS removal based on concatenation length. Long-chain molecules were more efficiently removed than their short counterparts.
How well did each make perform
Test results indicate that some brands did better than others. The researchers also found variability between a company'southward various models.
Berkey and Aquasana had the all-time PFAS removal of all pitcher filters – 98.8% and 99%. The performance of Brita filters varied significantly 8.iii% to 77.3%. In some tests, they removed most of the contaminants, simply in others they removed very niggling. PUR filters performed the worst of all brands tested.
Table 1: Bullpen Filter PFAS Sampling Results
| Brand | Age of Filter (months) | Total PFAS Tap H2o | Total PFAS Treated Water | Percent Removal |
| Brita | 1 | 57.2 ppt | 13.0 ppt | 77.three% |
| PUR | 1.five | 14.6 ppt | nine.4 ppt | 35.6% |
| Berkey | 12 | 16.1 ppt | 0.ii ppt | 98.8% |
| Berkey | vi | 14.ane ppt | 2.0 ppt | 85.8% |
| Berkey | 24 | 68.seven ppt | 30.7 ppt | 55.3% |
| Naught Water | 1 | 17.8 ppt | 2.5 ppt | 86.0% |
| Brita | 1 | 56.9 ppt | fifty.0 ppt | 12.1% |
| PUR | 1 | 647.6 ppt | 397 ppt | 38.7% |
| Aquasana | three | 48.3 ppt | 0.five ppt | 99.0% |
| Brita | 1 | xiii.2 ppt | 6.2 ppt | 53.0% |
| Brita | half-dozen | 23.0 ppt | 21.1 ppt | viii.3% |
Equally you can see, none of these filters removed all of the PFAS from the drinking water. Based on these results, would y'all desire your family drinking water that was merely purified with a Brita filter? I wouldn't.
What level of PFAS is safe
The EPA has established a health advisory level for PFOA and PFOS at 70 parts per trillion (ppt), but at that place are no national drinking h2o standards. Some states have ready lower maximum contaminant levels to protect public safety while others have put forth enforceable Maximum Contaminant Levels (MCLs).
California has the lowest drinking water standard – 5.1 ppt for PFOA. Michigan has the highest drinking h2o standard – 400,000 ppt for PFHxA.
Ideally, drinking water should have no PFAS in it. If that's non possible for you, then the lowest possible concentration of PFAS is what yous should aim for.
Bullpen Filters and PFAS
The bulk of well-known water pitcher filters, such every bit Brita and Pur, are not congenital to remove or lower PFAS in your tap water.
This statement tin can seem confusing considering these filters use activated carbon, and carbon is known to reduce PFAC levels in water. You may ask – If my Brita filter has carbon, shouldn't it treat PFAS?
Although bullpen type filters similar Brita contain carbon, the contact time in these filters is not long enough to remove PFAS to safe limits.
Contact time is the length of fourth dimension that water is in contact with the carbon. For PFAS, longer contact times are required.
An under-sink or whole-house carbon filter has at least 15 minutes of contact time. A Brita filter has much less. This is why they can generally remove only some of the PFAS.
Pitcher filter brands and PFAS
There are a variety of activated carbon filters that can remove PFAS chemicals, including refrigerator and faucet models. However, there is a wide range of efficiency between brands and models.
Bullpen filters are commonly used to remove gustation and olfactory property from drinking water. Some remove contaminants similar lead, VOCs, chlorine, mercury, and zinc.
Who makes pitcher filters? Hither is a partial list of manufacturers:
- Brita
- Pur
- Berkey
- Ballsy
- LifeStraw
- ZeroWater
- Hskyhan
Berkey claims that their filters remove 99.9% of PFAS and PFCs.
No other bullpen filter manufacturers claim to remove PFAS. We checked with Brita, Pure, Epic, and several others. They are all careful to avoid making claims that their filters remove PFAS from drinking water.
They don't claim to treat PFAS because their products are simply partially effective. This statement is backed up past several studies and reports. Go along reading for a review of these studies.
Pitcher filters must be maintained to remove PFAS
The downside to pitcher filters? They lose their effectiveness over time without regular maintenance. You have to replace the cartridge routinely because the activated carbon becomes spent.
The Knuckles study institute a meaning drib off in PFAS handling depending on how much water a filter had treated – so it's of import to replace your filter cartridges regularly!
Another business with pitchers – they simply work for certain types/forms of contaminants. Bullpen filters (and carbon adsorption in general) aren't constructive at removing sure compounds like PFOA and smaller PFAS molecules. This is why an under-sink carbon filter or reverse osmosis system may exist a better choice.
Third-party certification
Information technology's all-time if these products come with certification from third-political party certification organizations because not all brands perform equally. Some have this contained certification, but almost don't. Currently, the only independent certification for PFAS handling comes from NSF International (NSF).
NSF developed a certification test protocol for water treatment devices that are designed to remove PFOA and PFOS. The organization certifies all materials used in these products. They also verify manufacturer's claims about their effectiveness at reducing PFAS.
To exist certified by NSF, a device must reduce PFOA and PFOS concentrations in water to 70 parts per trillion. This is the health advisory level prepare by the U.Southward. EPA.
Yous tin can find certified products that care for PFOA and PFOS at NSF'due south listings page.
What Water Filters Remove PFAS

What'southward the most effective way to remove forever chemicals from your tap h2o?
Experts agree that a reverse osmosis system installed under your kitchen sink is the best selection bachelor to consumers. Duke tested these systems and institute they removed 96% or more of these toxins, with no divergence among brands.
RO systems are pretty expensive. An under-sink unit might toll around $300. You besides take to supercede the membrane once a twelvemonth. This might cost you $100.
They also waste a lot of h2o – simply about 20% of the contaminated water ends being treated. The residual is dumped down the drain.
Some other proficient option for your habitation is a carbon treatment organization. These devices use activated carbon to adsorb PFAS in your drinking water. This procedure effectively traps the contaminant on the carbon particles to provide make clean water.
Carbon systems must be properly maintained to provide continuous handling. The activated carbon only lasts and then long earlier it must exist replaced with fresh media. If yous don't keep up with the maintenance, the treatment efficiency declines and you might be at chance.
Boiling h2o does not remove PFAS (read our commodity to observe out why).
What is PFAS | Should I Be Concerned
PFAS chemicals, perfluoroalkyl and polyfluoroalkyl are man-made compounds that were developed for apply in household appurtenances and industrial applications. They were used to brand water-repellent fabrics, nonstick cookware, food wrappers, and fire-resistant furniture.
These forever chemicals persist in the environment likewise equally our bodies due to their long lasting nature. This is why they cease up in our drinking water.
PFAS chemicals cause all kinds of health bug. These include testicular and kidney cancer, thyroid affliction, ulcerative colitis, high cholesterol and preeclampsia.
What Do States Agencies Say Virtually PFAS Filters
It can be helpful to see what state wellness agencies recommend for filtering drinking h2o to remove PFAS. Hither is a list of states that take provided recommendations for h2o filters to remove PFAS, PFOA, and PFOS.
- Michigan
- Minnesota
- New Hampshire
- New Jersey
- New York
These states have provided guidance and factsheet documents on the two types of filters for removing PFAS chemicals: activated carbon, which adsorbs contaminants; or opposite osmosis.
They provide data virtually the pros and cons of each treatment arrangement and then that yous can make an informed decision nearly what would work best in your situation.
Do PUR Filters Remove PFAS
It's of import to know the difference between a water filter and purifier. Water filter systems, such equally PUR or Brita, are perfectly fine for reducing bad tasting chlorine, merely they were non designed to remove PFAS in your tap water.
Virtually pitcher filters are but partially constructive at removing PFAS. A few may even make things worse if they aren't properly maintained.
Duke conducted a report of bullpen filters. PUR filters removed an boilerplate of 37.2% of total PFAS.
PUR water filters are not suitable for filtering PFAS from drinking water. They can reduce the levels of PFAS, but non to below safe levels. For this reason, you should Not use a PUR filter to care for water contaminated with PFAS.

Do Berkey Filters Remove PFAS
The Berkey filter is a perfectly fine option to reduce bad tasting chlorine and other contaminants like heavy metals. All the same, it was not designed specifically for the removal of PFAS.
A study conducted by Duke researchers found that Berkey filters are only partially effective at removing PFAS from tap h2o. This study also ended that a poorly maintained filter rapidly looses its ability to care for contaminated h2o.
Berkey filters should not be used to care for PFAS contaminated drinking water. They can remove some of the PFAS compounds, only not consistently to below drinking water standards.

Exercise Epic Filters Remove PFAS
Epic filters should not be used to care for drinking water contaminated with PFAS or other perfluorinated compounds. These filters use activated carbon, so they can remove some of the PFAS. But, they can't remove all of it and they aren't able to treat the h2o to safe levels.
Practise not use Epic filters for PFAS handling of drinking water.

Do LifeStraw Filters Remove PFAS
LifeStraw water filters are great if you lot want to reduce the corporeality of chlorine and contaminants like heavy metals in your tap. Yet, they're not as effective for removing toxic perfluoroalkyl substances (PFAS). They weren't designed for removing PFAS or fifty-fifty reducing their concentration in tap water, which makes them only partially effective at doing and so.
Do not employ LifeStraw water filters to remove PFAS from drinking water. They can simply remove some of the PFAS, but not plenty to meet drinking water standards.

Do ZeroWater Filters Remove PFAS
For those concerned about the gustation and condom of their drinking water, a filter is an excellent option. Common types like ZeroWater volition reduce bad-tasting chlorine and common contaminants such as heavy metals. ZeroWater has NSF certification for PFOA and PFOS removal in tap h2o.
ZeroWater filters were only partially effective at removing toxic perfluoroalkyl substances in the Duke report. This is the nature of pitcher filters – they remove some of the PFAS compounds, but aren't as effective every bit RO.

Practise Hskyhan Filters Remove PFAS
Even though water pitcher filters like Hskyhan are perfectly fine if you want to reduce bad-tasting chlorine and heavy metal contaminants, they weren't designed for removing PFAS. While they might be able to partially treat contaminated h2o, they can't reduce PFAS concentrations to condom levels for drinking.
Hskyan filters are not appropriate for treating drinking water contaminated with PFAS.

Final Thoughts
Brita filters are not suitable for removing PFAS from drinking water. They take been shown to remove some of the PFAS contaminants, but they don't remove all of it.
Since the EPA'due south recommended level for PFAS is 70 ppt, Brita is non an adequate defence force against this chemic.
The best options for removing PFAS from drinking water are a opposite osmosis system installed under your kitchen sink, or a carbon treatment system used in conjunction with any other filtration device yous might accept already installed.
If you don't have whatever of these, you lot tin make do with the Brita filter. After all, some treatment is better than none.
