Airocide has one internal fan. Using Coanda-effect aerodynamics, air is drawn in through the front vent, accelerated through two catalytic reaction chambers and then amplified across a fine lip at the back center of the void. This ‘throws’ air further into the room while using the least amount of power.
The only maintenance needed is to replace the Reaction Chambers. The unit will prompt you with an indicator light when it is time to change (about once a year).
Airocide is intended for single room use and can handle any size room in your home.
