Air sterilisers work by sterilising the air as it passes through the machine. They work by convection so are completely silent.
The Airfree units us patented TSS technology (Thermodynamic Sterilisation System) that heats the air as it passes through the machine incinerating airborne microorganisms. The air is then cools down and the air that has passed through the machine is sterilised. The Airfree units take 14 to 21 days to completely work.
The Airfree units are silent so are good for bedroom or the living areas in the home. They are good for the removal of mould and mould spores but do not remove chemicals.
