Method for reducing allergenicity in indoor spaces

Abstract

According to this invention, allergenicity in an indoor space is reduced by denaturing allergens in allergen reservoirs that are capable of producing respiratory or skin reactions and physically removing the allergens from the allergen reservoirs in the indoor space. The allergen reservoirs may also be treated with pesticides and fungicides/fungistats to prevent reinfestation of house dust mites, molds and cockroaches.

         57 . 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 aerosolized 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. removing the at least one positively charged airborne allergen from the allergen reservoir.   
     
     
         58 . The method of  claim 57  further comprising a step after step b. of: physically removing the at least one positively charged airborne allergen from the allergen reservoirs in the indoor space by hot water washing. 
     
     
         59 . The method of  claim 58  further comprising a step of:
 drying the allergen reservoirs after the hot water washing. 
 
     
     
         60 . The method of  claim 57  wherein:
 said aerosolizing is accomplished via a fogger. 
 
     
     
         61 . 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 agglomerating agent into ambient air of an indoor space in a manner that completely fills the indoor space with the aerosolized polyester;   b. the aerosolized agglomerating agent staying airborne for a period of time that will allow the aerosolized agglomerating agent 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. removing the at least one positively charged airborne allergen from the allergen reservoir.   
     
     
         62 . The method of  claim 61  wherein:
 said negatively charged agglomerating agent is an acrylic latex. 
 
     
     
         63 . The method of  claim 61  wherein:
 said negatively charged agglomerating agent is a polyvinyl acetate. 
 
     
     
         64 . The method of  claim 61  wherein:
 said negatively charged agglomerating agent is a solubilized starch. 
 
     
     
         65 . The method of  claim 61  wherein:
 said negatively charged agglomerating agent is a polyvinyl alcohol. 
 
     
     
         66 . The method of  claim 61  wherein:
 said negatively charged agglomerating agent is an acrylic latex. 
 
     
     
         67 . The method of  claim 61  further comprising a step after step b. of: physically removing the at least one positively charged airborne allergen from the allergen reservoirs in the indoor space by hot water washing. 
     
     
         68 . The method of  claim 67  further comprising a step of:
 drying the allergen reservoirs after the hot water washing. 
 
     
     
         69 . The method of  claim 61  wherein:
 said aerosolizing is accomplished via a fogger.
