The Airfree P1000 has been tested by numerous independent international institutions that have verified and confirmed its drastic airborne microorganism and ozone reduction capacity. Inside Airfrees patented ceramic core 99.99% of all micro-organisms: spores fungus bacteria virus mold spores are incinerated at temperatures around 400F (250C). That is done without significant heat contribution to the ambient. No living microorganism survives this power. Airfree reduces Ozone whereas ozone generators generate dangerous levels of such harmful gas that destroys lung tissue triggers respiratory diseases and corrodes metallic equipment. Currently human beings spend 90% of their time indoors either at home or work. According to the EPA indoor air pollution can be up to 50 times greater than outdoor pollution. Consequently indoor air treatment is vital for healthy living. Being less exposed to allergy triggering sources and transmittable airborne diseases has countless health benefits.
