What is most efficient air purifier/cleaner for home? - carrier air purifier

I need an air filter in removing particles of pets, mold, dust mites, fumes, etc., preferably one that is not a filter that can be cleaned and returned to have the filters really expensive. I've heard are on the carrier Purif best, but not very secure. Find clean / clean approx. 800 square meters and has an air filter to radon and other gases that could be removed in a basement?
