Nature's Air Sponge spray uses a revolutionary new molecular process that breaks up odor molecules and eliminates them completely. Destroys odors through a chemical bonding process. It is not a perfume that simply covers up or masks odors. Instantly eliminates odors from most sources: Pet odors, humidity and damp basement odors, paint and solvent odors, tobacco and cooking odors, bathroom, car, boat, diaper pail, sports equipment, and footwear odors. Nontoxic because of the unique chemical process and nonallergenic. It is the only product in its category to enjoy the endorsement from the Asthmatic Association of Quebec. 22 oz. spray.
