20 oz, Chem-Dry Dust Mite Anti-Allergen Aerosol contains powerful active ingredients that deactivate the allergen, Der p1, found in dust-mite droppings by denaturing and substantially reducing the IgE antibody binding capacity of the allergen.

As a result, the allergen is no longer recognized by the body’s immune system and does not bond with antibodies sent to destroy it.
