EvaSeal s a natural, foaming, non-toxic, enzymatic mold protectant formulated to treat mold, mildew, bacteria, and associated odors. EvaSeal prevents the regrowth of mold and bacteria. EvaSeal works by changing the mold spores' chemical composition and converting them into harmless amino acids that have no allergenic potential or odors. EvaSeal seals and protects the evaporator coils from contamination associated with the damp climate of your air conditioner. The wet environment allows for living organisms to breed within the evaporator. EvaSeal's natural sealing foam will coat the evaporator fins. When the enzymatic foam liquefies, leaving a thin film coating. The protective coating will resist contamination growth such as mold, mildew, and bacteria that can cause foul odors and affect respiratory health.
