Asep-coat is a fast-acting deodorizer that exhibits anti-virus and anti-bacterial effects using photocatalyst. It uses "apatite coated with titanium dioxide", which is a material that is harmless to the human body, and is safe even if it adheres to small children, pets, food, etc. It decomposes and detoxifies bacteria, viruses, and odorous components by spraying on them. It also adsorbs viruses that float in the air and exhibits an excellent decomposition function. Normal photocatalyst is ineffective in the dark, but Asep-coat's "apatite coating" can adsorb bacteria and viruses in the dark night, and "titanium dioxide” decomposes during the day, so it is very effective for 24 hours efficiently.
