The Breeza deodorizing toilet seat features an innovative design and patent-pending 4-stage deodorizing system to provide a more comfortable bathroom experience for a family and guests by eliminating embarrassing odors. Power comes from two D-cell batteries, which last up to 9 months. The Breeza seat fits all standard US toilets and replaces your existing seat, installing in under 15 minutes. Perfect for shared bathrooms and powder rooms, the Breeza deodorizing toilet seat removes odors automatically through a battery-operated, 4 stage deodorizing process. The Breeza 4-stage deodorizing process begins automatically with a body-activated sensor. The quiet fan pulls air from the bowl, through an activated carbon filter. The filter absorbs 95.8 percent of odors before directing the air out into the bathroom through an optional aromatherapy vent. The Breeza seat’s innovative design provides a comfortable bathroom experience for your family and guests by eliminating odors directly from your toilet bowl. The Breeza’s gentle-closing seat and lid, anti-microbial components and comfortable, ergonomically design make this seat all the more evolutionary.
