The Kohler Purefresh is a toilet seat with an integrated carbon filter that can neutralize bathroom odors for six months before requiring a replacement (just change the carbon filter, not the seat). It uses a built-in fan, which activates as soon as somebody plops down on the seat, to draw odors to the filter, ensuring every stink is sucked in before it gets out to the room at large. Just to help further reinforce that your poop smells like roses, it comes with scent cartridges that will fill the air with a light, subtle scent. Three scents are available (garden waterfall, fresh laundry, and avocado spa), each cartridge of which can last a full month before needing to be changed.
Additionally, it comes with dual LED nightlights that illuminate the bowl for easy targeting during nighttime use. The whole thing powers using a pair of D batteries that can last for six months at a time.
Slated for availability soon, the Kohler Purefresh is priced at just under $90.
