Freshen your property’s carpets and reduce allergens in minutes. Arm & Hammer® Carpet & Room Allergen Reducer and Odor Eliminator features a unique powered formula that eliminates odors at the source and reduces the level of allergens in carpeting. Baking soda goes deep into carpets to eliminate odors, while allergen reducers break the static charge that binds allergens to carpet fibers, releasing the allergens that are then easily vacuumed up. Simply sprinkle on the carpet, let it sit, and then vacuum the area thoroughly. It leaves a light, pleasant scent to keep carpets smelling fresh.
