Airfree Manuals & User Guides

Airfree is a global leader in natural air purification, known for its innovative approach to indoor air quality. Established in Portugal, the company designs and manufactures silent, filterless air purifiers that rely on the patented Thermodynamic Sterilization System (TSS™).

Instead of capturing pollutants in filters that require frequent changing, Airfree’s technology works by drawing contaminated air into a ceramic core. Inside, the air is heated to high temperatures to destroy organic allergens and microorganisms—including mold, bacteria, and viruses—before being cooled and returned to the room. This efficient, maintenance-free process produces no ozone or ions, making Airfree a preferred choice for nurseries, bedrooms, and offices in over 60 countries.

• How do I know if my Airfree unit is working?

  Check the top lid of the device. If the top lid is warm to the touch, the Thermodynamic Sterilization System (TSS™) is functioning correctly. The unit operates silently, so heat is the primary indicator of operation.

• Do Airfree air purifiers require filter replacements?

  No. Airfree purifiers utilize a heated ceramic core to destroy impurities rather than trapping them in a filter, so they are maintenance-free and require no replacement parts.

• Does the Airfree purifier generate heat in the room?

  While the ceramic core heats up to sterilize the air, the contribution to the room temperature is insignificant. Two Airfree devices in the same room generate roughly as much heat as one adult human.

• Does Airfree eliminate bacteria and viruses?

  Yes. The TSS™ ceramic core destroys 99.99% of all microorganisms, including bacteria, viruses, and mold spores, as they pass through the heated ducts.

• Should I turn off the Airfree purifier when I leave the house?

  No. For maximum efficiency, Airfree units should remain on 24 hours a day to maintain the cycle of air sterilization and prevent contamination from returning.
