The Airfree system uses the most modern way of environmental control. Its indicated to reduce drastically the population of microorganism in the environment and also reduce the airborne allergen proteins. Airfree® is the only technology that safely destroys airborne allergens, mold spores, mildew, dust mite allergens, viruses, bacteria, and pet dander. Airfree® does not use harmful emission such as UV light or ozone. Airfree® uses heat instead with no noticeable heat contribution to the room temperature. Airflow is quietly achieved through air convection generated by Airfree® ´s patented Thermodynamic Sterilizing System (TSS™) that sterilizes air at high temperatures. Cooler air is then continuously drawn into Airfree®. No need for a noisy fan. No moving parts and best of all, no maintenance!
