Oxy-Gen powered fragrance cartridges contain Neutra-lox, a proprietary odor neutralizing agent to eliminate bad odors, instead of masking them, leaving only fresh scent in the air. Neutra-lox effectively eliminates bad odors such as tobacco, kitchen odors, sweat, mildew, animal, fecal and body odors. The cartridges contain up to four times more fragrance oil compared to standard aerosol cans and each unit can successfully cover an area of 3000 cubic feet.
