Airfree uses a unique technology that destroys allergens, mould spores, mildew, dust mite allergens, viruses, bacteria and pet dander. It works by drawing air into its patented incineration chamber where inside the tiny ducts of the ceramic core , up to 99.99% of micro-organisms are incinerated. Poisoning gases like ozone are also destroyed along with all allergens such as pollen, dust mite faeces and pet dander. The heat used in Airfree has no noticeable effect on the ambient heat of the room and the unit itself is not hot to the touch.
