Patent ID: 8025905

Claim:
A method for reducing allergenicity in ambient air of an indoor space in need thereof, said ambient air having at least one positively charged airborne allergen and said indoor space having allergen reservoirs, said at least one positively charged airborne allergen having polypeptide structures that render the at least one positively charged airborne allergen allergenic, said at least one positively charged airborne allergen selected from the group consisting of house dust mite fecal antigens, cockroach fecal antigens, cat dander, dog dander, mold spores, and combinations thereof, the method comprising: a. aerosolizing a negatively charged polyester into ambient air of an indoor space in a manner that completely fills the indoor space with the aerosolized polyester; b. the aerosolizing polyester staying airborne for a period of time that will allow the aerosolized polyester to attract at least one positively charged airborne allergen and weigh down the at least one positively charged airborne allergen so that the at least one positively charged airborne allergen will settle into an allergen reservoir; and c. applying to said allergen reservoir a means for hydrolytically cleaving the at least one positively charged airborne allergen that settled into the allergen reservoir, thereby breaking peptide bonds and the polypeptide structure of the at least one positively charged airborne allergen and reducing the polypeptide to peptide fragments that are less allergenic and more easily removed from the allergen reservoir; and d. removing the at least one positively charged hydrolytically cleaved airborne allergen from the allergen reservoir.
