How can i clear my annoying house allergy?

Indoor allergens : Indoor allergens are usually dust mites, pollens, molds, cockroache, and/or animal danders. Environmental control, minimizing exposure, may be of some help as are topical/oral medication. If those are not adequate allergen immunotherapy is usually indicated. In rare extreme situations you might need ro move, but the "grass isn't always greener". Need to see board certiified allergist.
