Trusted Air Purifier Brands & Companies List

Airfree Logo


Airfree is a manufacturer based in Portugal.

This air purifier brand is well known for cleaning the air through the use of its patented Thermodynamic Sterilizing System (TSS) Technology.

This technology operates completely different than the use of a filter, which is what many other air purifier manufacturers use to capture harmful pollutants. (You can learn more about how does an air purifier work here.)

Airfree’s technology works by pulling air into a chamber through a convection system and then heats up the air to over 400 ºF.

This extremely hot air neutralizes and kills microorganisms by incinerating them as they pass through the system.

Airfree’s technology has been tested and proven by the INETI and numerous other international laboratories.

Their products destroy 99.9% of all organic particles that pass through the air cleaner, including bacteria, viruses, mildew, mold, dust mites, allergens, pollen and tobacco odors.

Because Airfree’s technology is so good at killing germs, we highly recommend it as one of the best air purifiers for bacteria, viruses and germs.
