Meet the Odorless: an eco-friendly fan that filters odor directly from your toilet bowl to keep your bathroom odorless. It is easy to install and eliminates odor naturally. When you are ready to go, the motion sensor turns the unit on. The device lets you know when it is running low on battery.
The Odorless system filters the air directly from your toilet, so it is pretty efficient. You can fund this eco-friendly kit on Kickstarter.
