This is the toilet seat that immediately suppresses bathroom odors by deodorizing the ambient air. As you sit on the seat, a whisper-quiet fan passes air through a replaceable carbon filter that absorbs odors, and is then freshened with one of two included fragrance modules, infused with pleasing, natural extracts, including Jasmine/Lavender and Citrus/Eucalyptus. The carbon filter deodorizes for six months and the fragrance module freshens for one month. Seat is made of durable, anti-microbial polypropylene. Requires two D batteries for nine months of use. Round seat. (6 lbs.)
