AirFree Lotus Filterless Air Purifier & Sterilizer
  • AirFree Lotus Filterless Air Purifier & Sterilizer

    With its patented Thermodynamic Sterilizing System (TSS) technology, the Airfree Lotus Filterless Air Purifier harnesses the natural power of heat to silently destroy airborne allergens, dust mites, bacteria, viruses, and other contaminants.


    With no filters to clean or replace, it requires zero maintenance. Lightweight but powerful, this energy efficient unit is ideal for cleaning the air in spaces up to 650 square feet.

    How Does It Work?

    Destroy 99.99% of allergens and other microorganisms in a fraction of a second with Airfree’s unique TSS technology. The Airfree Lotus continually draws air into the unit by air convection. Impurities are then eliminated by heating the air to temperatures close to 400 degrees Fahrenheit.

    Before the purified air is released back into your space, it’s first cooled ensuring that it has no effect on the temperature of your room. 

    Silent, Efficient and No Maintenence 

    Without any fans, motors, or moving parts, it’s constantly cleaning your air without making a sound. Since there’s not an ionizer, it’s completely safe to use with no ozone or ion emissions created.

    Without any filters to clean and replace, you’ll save time and money with this no-maintenance-required air purifier. Only using 52-watts of electricity, less than a 60-watt light bulb, it’s also easy on your power bill.

    Unique Design

    While it’s purifying the air, it also emits different colored lights to help create a welcoming environment. Select your desired color and even adjust the intensity of the light to match your mood.


    Standing only slightly over a foot tall and weighing just 5.2 pounds, the Airfree Lotus takes up little space and is lightweight enough to be moved from room to room.
