From Controlling Dry Wall Dust to Saving the Environment
In 1999 in a garage on Maui, Hawaii, Roy Pellegrin developed a filter to capture drywall dust at building sites. In the process he discovered a fundamental new filtering technology, the Aqueous-Froth Air (AFA) Filter.
From 2005 to 2007, the Pacific International Center for High-Technology Research funded R&D with Peletex to contract with
Sandia National Laboratories, where the AFA Filter was tested for use with their decontamination foam.
The result was proof of concept, documented in December 2005. A second contract advanced the design of the AFA Filter. Nucleation provided the capacity to capture smaller particles than conventional air filtration systems. Testing against anthrax achieved 99.999% capture and kill results.
