The AIRFREE DUO 645ft. Air Sterilizer offers an innovative, filterless solution for air purification in spaces up to 645 square feet. Utilizing its patented Thermodynamic Sterilizing System (TSS™) technology, this appliance silently and efficiently destroys airborne microorganisms, contributing to a cleaner and healthier indoor environment without the need for replacement filters or complex maintenance.

Product Overview

The Airfree DUO air sterilizer is engineered to deliver superior air purification through Airfree's exclusive patented Thermodynamic Sterilizing System (TSS™) technology. This system works by drawing air into a heated ceramic core, reaching temperatures of approximately 200°C (400°F). At these extreme temperatures, airborne allergens and microorganisms, including viruses, bacteria, mold spores, dust mite allergens, and pet dander, are incinerated and effectively eliminated. The process is completely silent, ozone-free, and requires no maintenance, making the Airfree DUO an ideal choice for anyone seeking a highly effective, quiet, and hassle-free solution for healthier indoor air in homes, offices, or other enclosed spaces.
