RGF® Air Purifiers will not cure allergies or asthma or other breathing problems. They are not designed specifically for the treatment or prevention of any health problem or ailment. However, it has been shown that most asthma and allergy sufferers do benefit greatly from the pollutant reduction these units provide. Mold, pollen, dust, animal dander, dust mites, chemical gases, and other common allergens are all effectively reduced in a RGF® environment.
