Air purifier recommended for rooms up to 60 m-square. Airfree is the natural solution to asthma, respiratory allergies & mould. Eliminates dust mites, bacteria, fungi, virus, pollen, allergens of domestic animals & other microorganisms from the air. How does it work? Airfree’s exclusive technology works by eliminating microorganisms & allergens, destroying them in a fraction of a second. Depending on the model, between 14, 000 & 20, 000 litres of air pass through the Airfree device every hour, treating all the air in the room in a very short space of time. The process works in much the same way as sterilising water by boiling it; when water is boiled, the microorganisms it contains are eliminated. In similar fashion, Airfree continually draws in air from the room, heating it to over 200 degrees C & instantly sterilising it. The purified air is then cooled inside the device before being returned to the room. The entire process is completely silent & requires no maintenance, not even the occasional replacement of parts. All you have to do is switch the device on & leave it to get on with the job.
