What circulates the air through an Airfree Air Sterilizer?
Convection causes the air to circulate through your Airfree. Air in the Thermodynamic Sterilization System core is heated to over 400°F which causes it to rise. Air is pulled in through four air intake ports at the bottom of the Airfree. Air is cooled to a slightly warm temperature and expelled through the top. The convection approach to circulating the air is what makes your Airfree the most quiet air purifier (sterilizer) on the market.
