PFAS Filter Pitcher for Brita
The new Brita filter from Cyclopure, Inc. can remove perfluoroalkyl or polyfluoroalkyl substances (PFAS) from drinking water. The Purefast cartridge provides up to 65 gallons of pure H2O – this is equivalent to 700 bottles of water.
These new filters are available for $45 directly from Cyclopure. Here is a link to their order page.
Cyclopure is a materials science and environmental engineering firm based in Skokie, Illinois. The company has developed a novel adsorbent – DEXSORB® – that can remove PFAS compounds from water.

Purefast PFAS filter cartridge for Brita
The Purefast filter cartridge was developed using Cyclopure’s innovative adsorbant material called DEXSORB. This filter media is made from corn starch and can remove most PFAS molecules from water. It is more effective than activated carbon and ion exchange resins.
Cyclopure notes that this Brita filter cartridge is an eco-friendly product – it is made from a renewable agricultural product. It is highly effective at removing forever chemicals to make your tap water safe again.
The filter is as easy to use as other Brita pitcher filters. Simply fill the pitcher basin with your home’s tap water, and you will have PFAS-free water in about 20 minutes.
PFAS compounds removed by Brita filter
This new Purefast filter is effective for the removal of the following 11 PFAS compounds:
- PFOA
- PFOS
- PFHxA
- PFHxS
- PFNA
- PFDA
- PFHpA
- PFPeA
- PFBS
- PFBA
- HFPO-DA (GenX)
How does the Purefast filter work?

The new DEXSORB+ system is a game changer for those who want clean water. It uses renewable cup-shaped cyclodextrins, derived from corn starch and specifically designed to bind all 40 EPA targeted PFAS compounds.
This new adsorption technology can rapidly bind a variety of PFAS compounds faster and more efficiently than other filtration materials, like activated carbon.
NSF certified to remove PFAS
The Purefast filter cartridge has been tested by NSF International for PFAS treatment. This filter is certified by NSF to treat 65 gallons of water to reduce the concentration of PFOA and PFOS in accordance with NSF/ANSI 53.
This filter is also certified by NSF for reduction of chlorine in accordance with NSF/ANSI 42.
NSF certification is the gold standard for home filters. They provide independent testing and verification that a product meets specific standards for public health and safety.
Funding from NIEHS
This new PFAS water filter was developed by Cyclopure through a small business innovation research grant provide by NIEHS Superfund Research Program. Grants like these allow small businesses to get the funding they need to develop new products that can have a big impact on public health.
More About the Brita PFAS Filter from Cyclopure

The new Purefast filter was the result of 2 years of R&D by Cyclopure. The company previously developed a PFAS home test kit that measures 55 specific compounds. They also developed an innovative corn starch media called DEXSORB+ that removes a variety of PFAS from water.
The new Brita filter is the first product to use this DEXSORB+ media. It is a major step forward in terms of water filtration, and it could mean a big difference in terms of your health and safety.
Test results for PFAS removal
NSF tested the Purefast filter for PFAS reduction according to NSF/ANSI standard 53. This test evaluates PFOS and PFOA removal. A water filter must be capable of reducing PFOA and PFOS concentrations to below the EPA recommended limit of 70 parts per trillion to receive an NSF Certification.
NSF periodically retests all certified products and the facilities where they are made to ensure products continue to meet all requirements.
Great customer reviews
You can’t rely on customer reviews to know how well a filter removes a contaminant like PFAS. This is why you want NSF certification.
You can, however, get a sense of the overall quality of the filter, how easy it is to use, and any problems it might have.
The reviews I’ve seen have all been very positive. Everyone gave the product 5 stars. Check out the verified reviews from Trustpilot.
Disposing of the Purefast cartridges
A nice feature of the new Purefast filter is you can dispose of it in a responsible way. Each Purefast cartridge comes with a prepaid label so you can send the filter back to Cyclopure’s facility.
In their laboratory, Cyclopure removes the contaminants from the filter media and converts them into salts. These waste materials are safely disposed without harming the environment.
Cyclopure can also regenerate the spent DEXSORB+ media. This allows the adsorbant to be re-used for a variety of water filtration purposes. All of these practices are very sustainable, especially compared to other filters that you throw away in the trash.
What is PFAS
PFAS are a group of man-made chemicals that have been used in many industries since the 1950s. They are found in products like nonstick cookware, water-repellent clothing, stain-resistant fabrics and carpets, some cosmetics, and firefighting foams.
These chemicals can be released into the environment when these products are made or used. They can also enter the environment when PFAS-containing products are disposed of in landfills or incinerated.
PFAS are sometimes called “forever chemicals” because they do not break down in the environment and can accumulate in people and animals over time.
How does PFAS contamination get into my drinking water?
These contaminants typically enter the environment through manufacturing and industrial sites, wastewater treatment plants, and landfill leachate. They can also be found in some consumer products, like carpeting, clothing, and cosmetics.
PFAS have been detected in drinking water supplies near manufacturing sites and wastewater treatment plants that release these chemicals into the environment. In addition, PFAS have been found in some private wells near these sites.
The U.S. Environmental Protection Agency (EPA) has established drinking water Health Advisories for two PFAS compounds: PFOA and PFOS. These Health Advisories provide guidance on levels of these compounds that are safe for people to drink over a lifetime.
EPA guidelines for PFAS in drinking water:
- PFOA – 0.004 (interim)
- PFOS – 0.02 (interim)
- GenX Chemicals – 10 (final)
- PFBS – 2,000 (final)
Health effects of PFAS
PFAS can potentially cause a number of health effects, including:
- Cancer
- Thyroid problems
- Immune system problems
- High cholesterol
- Hormone disruption
- Reproductive and developmental problems
These chemicals can also build up in people and animals over time. Studies have shown that PFAS can stay in the human body for many years.
The health effects of PFAS depend on how much exposure a person has to these chemicals and for how long. Some health effects may happen right away after someone is exposed, while others may not occur until years later.
FAQs
Do Brita pitcher filters remove PFAS and GenX compounds?
Only Brita pitcher filters with the Purfast filter cartridges can remove 100% of PFAS. These filters are certified by NSF to reduce PFOA and PFOS to less than 70 parts per trillion. Read my article on Brita pitchers and PFAS treatment.
Do Pur pitcher filters remove PFAS?
Pur pitcher filters do not remove 100% of PFAS from drinking water. They use activated carbon, which is effective at PFAS treatment. However, the Pur pitcher filters are not designed to remove PFAS, and they do not have enough activated carbon. The Pur pitcher filters should not be used to purify your drinking water.
Do ZeroWater filters remove PFAS?
ZeroWater pitcher filters can remove PFAS compounds from drinking water. These filters are NSF certified to reduce PFOA and PFOS concentrations in water to less than 70 ppt. Read my article on ZeroWater pitchers and PFAS treatment.
Do Carbon filters remove PFAS compounds from drinking water.
Activated carbon filters are very effective at removing PFAS from water. Carbon filters can remove up to 99% of these contaminants. Read my article on carbon filters and PFAS treatment.
The Bottom Line
The new Purefast filter is a great way to remove PFAS from your drinking water. This filter is designed to work with all Brita pitcher filters. It has the same connection and configuration as their other cartridges, which makes it is easy to use and install.
The Purefast filter is certified by NSF to remove PFOA and PFOS from drinking water. It also reduces other PFAS compounds, like GenX chemicals. This filter is a great way to make sure that your drinking water is safe and clean.
