Cyclopure announced the introduction of two new whole-home filters to remove per- and polyfluoroalkyl substances (PFAS) from household water: Purefast Home80 and Purefast Home20.
Cyclopure says that these point-of-entry water filtration systems use the company’s DEXSORB adsorbent to remove PFAS to non-detect levels at the cost of one penny per gallon.
Purefast Home80 is a floor-standing vessel designed to provide 80,000 gallons of treated water before replacement. Purefast Home20 is a compact filter, compatible with Big Blue Filter housing uinits, with a 20,000-gallon treatment capacity.
"We are pleased to offer DEXSORB in a whole-home PFAS treatment solution for households," said Yuhan Ling, chief product officer at Cyclopure. "It's the same adsorbent that we use to remove PFAS in large-scale PFAS treatment applications. Purefast Home is the only filter unit to provide non-detect, less than 1 ppt, PFAS removal from tap water."
Filters can be replaced through Cyclopure's filter exchange program. Participating customers will receive 25% off the purchase of a replacement filter when they return their used filter to the company. When a filter is returned to Chicago, spent DEXSORB media is regenerated in a process that separates and concentrates extracted PFAS. Regenerated DEXSORB is repurposed for non-drinking water uses. In a final process step, Cyclopure says it uses destruction technologies to fully destroy PFAS waste and prevent recontamination of the environment.
The Purefast Home filters expand Cyclopure's line of DEXSORB PFAS products for the home. They join the company's home Water Test Kit for PFAS and its Purefast Filter for Brita countertop pitchers introduced in January 2020 and May 2022, respectively.
Both filters are compact, with Purefast Home80 measuring 6" (D) x 42" (H) and Purefast Home20 measuring 4.5" x 20", making for easy plumbing connection to the home water line.
In addition to PFOA and PFOS, Cyclopure says that Purefast Home filters have been tested for non-detect removal of PFHpA, PFHxS, PFNA, PFBS, GenX, and PFDA – covering the EPA PFAS 6 and all 7 PFAS covered by NSF ANSI 53. DEXSORB is also blended with granular activated carbon to provide chlorine reduction for taste and odor.
