Botanical deodorizer adopts micro-molecule extraction technology and extracts effective ingredients from many kinds of plants. It can decompose and transform the source of odor, effectively degrade the organic substances in the source of odor, reduce the content of ammonia and nitrogen, remove the odor with remarkable effect, and inhibit the reoccurrence of odor more effectively. The removal rate of ammonia can reach 96%, and the removal rate of hydrogen sulfide can reach 90%.
