How does it work?

Utilizing a patented technology the fart fan has the capacity to work in reverse. As a resulty the Fart Fan allows for providing fresh air and exhaust air through one duct.


A simple solution for a complex problem.  

The fan's normal operation setting is on supplying fresh air to the habitable space. The exhaust mode will be triggered in one of two ways; (i) humidity sensor, or (ii) manual switch. 

The smart control panel on the Fart Fan allows the exhaust operation for a maximum of 20 minutes prior to reverting back to supply mode.
