Cyclopure is solving water contamination problems by filtering micropollutants with pioneering adsorption technologies. Dr. Dichtel is the Robert L.

Contamination of water resources by micropollutants is a global health and environmental problem, with greatest risk to infants and unborn children who are most vulnerable to the toxic loads of these chemical compounds. Advanced analytics have shown that trace organic compounds including residuals of pharmaceuticals, pesticides, detergents, and cosmetics, are persistent in water and retain toxic effect at extremely low concentrations. CycloPure was formed to commercialize novel adsorption technologies pioneered in the lab of Will Dichtel at Cornell University. Letsinger Professor of Chemistry
at Northwestern University, and heads the Dichtel Research Group in the University’s Department of Chemistry. Using these technologies, CycloPure is developing a new class of highly adsorbent and sustainable materials for rapid removal of micropollutants from water. The company’s water treatment technology can be incorporated into a variety of filtration products for domestic, industrial, hospital and municipal applications, including purification and conditioning. CycloPure is also developing the technology for use in functionalized fabrics to remove volatile organic compounds (VOCs) and other contaminants from air.

When we introduced our PFAS Water Test Kit Pro in 2020, our goal, backed by funding from the National Institute of Environmental Health Sciences, was simple: give homeowners an accurate, affordable way to test their water. 💧

Thanks to you, the Test Kit has grown far beyond that original mission. Today it’s used by homeowners, environmental groups, schools, universities, municipalities, state agencies, and even the U.S. Navy. It has traveled to all 50 states and around the world: from Japan and the Netherlands to Mexico, Peru, Trinidad & Tobago, and Bangladesh. 🌍

With your trust and support, we’ve tested 30,000+ samples and received photos from classrooms and communities proudly holding up their test cups. These moments mean everything to our team.

To keep delivering the same high-quality testing and fast turnaround you count on, the Water Test Kit Pro price will increase to $85 + shipping on January 1, 2026. Return-shipping postage will continue to be included.

Thank you for an incredible six years, and for making this journey so meaningful. 💙

The Purefast HomeXtreme is a 160,000-gallon, DEXSORB® POE filter that protects your home water from toxic PFAS chemicals. The Fremen Stillsuit is a POU filter that treats P*e Fast to make potable water. For PFAS, the choice is obvious. You’ll taste the difference.

Kim and Mike Condurso toasting to 850 days and 105,000 gallons of PFAS-free water! Their Purefast® Home80 has blown past the filter’s 80,000 gallon rating, continuing to remove all EPA PFAS from their well (avg. 29.0 ppt) to non-detect. Thanks for trusting DEXSORB® to keep drinking water safe at the Condurso family home in New Jersey. 💧 Read the full Condurso case report here: https://tinyurl.com/CondursoPurefastHome80

Our Story

We are a material sciences and technology company whose mission is to make drinking water safe for everyone, everywhere. We are commercializing a new class of selective and powerful adsorbents called High-Affinity Cyclodextrin Polymers (HACPs) that are uniquely capable of removing the toxic micropollutants that contaminate much of our drinking water supply and threaten the health of millions every day. These micropollutants include industrial chemicals, pharmaceuticals, and pesticides that, even at trace concentrations (parts per billion), have been linked to multiple cancers, endocrine disorders, thyroid disease, and immunotoxicity.

Because they exist at trace concentrations, micropollutants easily pass through the municipal water treatment plants which supply tap water to over 85% of the U.S. population. Many also pass through Point-of-Use water systems that millions have installed in their homes. It is the reason that some micropollutants, such as carcinogenic per- and polyfluoralkyl compounds, are now found in the blood serum of 97% of Americans.

Our invention of porous High-Affinity Cyclodextrin Polymer (HACP) adsorbents represent a breakthrough solution for the safe, rapid, and cost-effective removal of toxic micropollutants from water. Our patented technology can be easily incorporated into most water treatment applications including municipal drinking water and wastewater treatment systems, industrial water treatment facilities, and in consumer Point-of-Use water purification products.
