Environmental components – April 2022: PFAS water filter developed by means of NIEHS funding

A brand new filter cartridge suitable with Brita pitchers can take away per and polyfluoroalkyl substances (PFAS) from ingesting water. Cyclopure, Inc. What are Okay PureFast cartridges based mostly on? Dexsorb+(https://www.niehs.nih.gov/analysis/supported/facilities/srp/science_digest/2019/6/know-how/index.cfm) The know-how, which was developed with help from the NIEHS Superfund Analysis Program (SRP) Small Enterprise Innovation Analysis Grant(https://instruments.niehs.nih.gov/srp/applications/Program_detail.cfm?Project_ID=R44ES029401),

“These $45 filters can present as much as 65 gallons of PFAS-free water, changing 700 single-use water bottles,” mentioned Frank Cassou, CEO of Cyclopure. Cartridges shall be accessible in early April 2022.

“We hope this shall be an inexpensive possibility for these involved about PFAS publicity the place they dwell or work,” he mentioned.

“Britta pitchers are accessible to an enormous demographic and set up would not require an professional like a plumber,” Cassou mentioned. “It permits us to simply present protected and inexpensive ingesting water.” (Photograph courtesy of Cyclopure)

“The aim of the SRP Small Enterprise Grants program is to create instruments that may enhance folks’s well being,” mentioned SRP Well being Scientific Administrator Heather Henry, PhD, who leads this system. “Cyclopure is doing simply that. It’s a outstanding achievement that simply 4 years after their grant started, they’ve launched a product that may assist communities cut back their publicity to PFAS.”

environment friendly know-how

DEXSORB+ makes use of renewable cup-shaped cyclodextrin, derived from corn starch, to bind and take away all 40 PFAS focused on the US Environmental Safety Company (EPA). PFAS Roadmap,

“Our cyclodextrins are very small, 0.78 nanometers to be exact, and in a single gram of DEXSORB+, there are over 300 quintals of cyclodextrin cups,” Cassou defined. “This permits our know-how to bind quite a lot of PFAS compounds sooner and extra effectively than different filtration supplies reminiscent of activated carbon.”

on March 17, Nationwide Sanitation Basis (NSF) Worldwide licensed this filter environment friendly and protected for ingesting water remedy and permitted its use for business functions.

“Creating PureFast was a two-year course of,” Cassou mentioned. “We put PureFast by means of rigorous testing underneath quite a lot of circumstances to make sure that efficiency was inside the NSF’s PFAS restrict of 70 elements per trillion. Within the lab, we verified zero PFAS detection for 65 gallons of water filtration. Of.

Illustrated example of how DexSorb+ uses renewable cup-shaped cyclodextrin derived from corn starch to bind and remove all 40 PFASs targeted at the US Environmental Protection Agency (EPA) Cyclopure describes its know-how as “science by nature” as a result of cyclodextrins are constituted of corn and the small molecules are completely suited to seize and take away contaminants.

Prioritizing sustainability, wholesome communities

“Sustainability is considered one of our high priorities,” Cassou mentioned. “We’re working arduous to make sure that all supplies are correctly and safely disposed of or reused.”

Every PureFast cartridge comes with a package deal and pay as you go label that returns the filter to Cyclopure’s laboratory, the place the contaminants shall be transformed into salts and disposed of safely with out harming the setting.

In Cyclopure’s lab, DEXSORB+ can be regenerated, permitting the group to reuse their know-how for quite a lot of water filtration functions.

His group of consultants works carefully with communities throughout the US with excessive ranges of PFAS contamination, recurrently testing their ingesting water provides and speaking the outcomes. Certainly one of their accomplice communities in Massachusetts not too long ago bought 3,000 models to supply protected ingesting water to all houses of their metropolis.
