Get Pure Fast

Rapid Removal

DEXSORB®’s tiny sub-nanometer cups are perfectly sized to target and scoop out PFAS. 300 quintillion cups in each gram of DEXSORB® allow rapid removal of PFAS upon contact, creating an adsorbent barrier that blocks further passage of the toxin.

High Capacity

Three’s a crowd. Large materials in water can muscle in to block adsorption of PFAS in other absorbents. DEXSORB’s uniform sub-nanometer cups deflect large materials by size exclusion, reserving their adsorbent capacity for PFAS.


DEXSORB is the first-ever, corn-based adsorbent to purify water. Using renewable cyclodextrins for adsorption of PFAS helps keep access to drinking water affordable.


Whereas other adsorbents are single-use, DEXSORB® can be regenerated for multiple cycles of use, providing cost-effective treatment efficiencies.
