What CycloPure does
CycloPure, Inc. is a Delaware-incorporated materials science company founded in 2016 that develops and commercializes DEXSORB®, a proprietary renewable adsorbent engineered to remove PFAS (per- and polyfluoroalkyl substances) from water. Its core offering sits at the intersection of a novel adsorbent chemistry and a validated analytical workflow: DEXSORB+ is used in passive sampling extraction discs that capture PFAS for downstream quantification via isotope dilution LC-MS/MS on Thermo Scientific Q-Exactive instrumentation, validated under EPA Method 537 down to 5 ppt.
The company's revenue model is hardware-led and direct-to-consumer. Through cyclopure.com it sells a $45 Purefast Countertop pitcher filter, an $800 Purefast Home80 whole-home POE system with a $700 replacement vessel, a $1,200 Purefast HomeXtreme high-capacity POE system with a $1,100 replacement vessel, and an $85 Water Test Kit Pro that screens 55 PFAS analytes including all 40 EPA Method 1633 compounds. Replacement vessels create a recurring consumable stream from the installed base, and the test kit functions as a low-friction entry point into filtration purchases. CycloPure has also opened an Engineered Systems vertical for commercial and municipal-scale PFAS treatment, though the D2C consumer channel remains the dominant and most visible go-to-market motion.
CycloPure serves homeowners and households concerned about PFAS contamination in drinking water, with named testimonial customers across residential deployments and water treatment projects. Leadership is anchored by co-founder and CEO Frank Cassou, the company maintains its headquarters in Evanston, Illinois with operating presence indicated in Encinitas, California, and the capital base has been built primarily through non-dilutive U.S. federal awards (NSF, NIEHS) supplemented by a 2026 strategic investment from Japan's Kurita Water Industries. The company has not disclosed revenue and operates without disclosed institutional VC backing.

CycloPure competitors and assessment
Company assessmentDirect peers
- Hydroviv: Sells customized under-sink water filters based on local water quality reports, with PFAS-specific offerings. Comparable D2C, science-forward positioning targeted at PFAS-aware consumers.
- iSpring Water Systems: Direct-to-consumer reverse osmosis and whole-home filtration systems sold online. Comparable on product category and D2C channel, with broader filtration use cases beyond PFAS.
- Aquasana: Direct-to-consumer and retail home water filtration brand offering whole-home, under-sink, and shower filters with contaminant-reduction claims including PFAS. Closely comparable product line and target customer.
- ClearlyFiltered: Direct-to-consumer brand selling PFAS-specific under-sink and whole-home water filters with third-party testing claims. Closest comparable on positioning, target customer (PFAS-aware homeowners), and product architecture.
- Epic Water Filters: Sells PFAS-reducing home water filters (under-sink and pitcher) directly to consumers with similar contamination-reduction claims. Competes head-to-head with CycloPure in the same niche buyer segment.
Broad incumbents
- Brita (Clorox): Dominant consumer water filtration brand with mass retail distribution. Overlaps with CycloPure's countertop/pitcher use case but at much broader scale and lower price points; represents the mainstream incumbent CycloPure must differentiate against.
- PUR (Helen of Troy): Major pitcher and faucet-mount water filter brand under Helen of Troy. Overlaps with CycloPure on consumer household filtration but at the mass-market tier with established retail presence.
- Culligan: Large established water treatment company with whole-home filtration, softening, and commercial offerings. Overlaps with CycloPure's POE use case but via dealer/installer network rather than direct e-commerce.
- Pentair: Global water treatment company with residential and commercial filtration portfolios. Competes broadly in the same end markets as CycloPure with much larger scale and channel reach.
Others
- Kurita Water Industries: Japanese global water treatment giant and CycloPure's 2026 strategic investor. Not a direct competitor but a relevant peer for the industrial/municipal PFAS remediation market CycloPure is targeting through its Engineered Systems line.
