The compact Airfree Onix 3000 Air Purifier is a filter-less air sterilizer that uses a patented ceramic core technology to heat air inside the unit to 400°F, destroying 99.99% of airborne microorganisms and pollutants, including mold spores, fungi spores, viruses, bacteria, pollen, dust mite allergen, and even ozone, all which are continually drawn into the unit by a process known as air convection. Unlike air purifiers with filters, which require noise-producing fans to push air through the filter, the Airfree Onix 3000 is completely silent in operation – a real bonus, particularly when used in a bedroom, or in community settings like schools and libraries. Airfree Onix 3000 is for rooms up to 650 square feet.

The Airfree Onix 3000 produces no ozone, ions or harmful emissions of any kind. Additionally, although the Onix 3000 kills microorganisms at a very high temperature, it is very safe to use and only mildly warm to the touch (at top). It is designed to be run continuously, with no noticeable increase in room temperature or relative humidity. The Onix 3000 is simple to use, and very energy efficient – costing only 10-12 cents a day to run. And because the Onix 3000 uses no filters or UV bulbs, the burden of ongoing maintenance and replacement costs is non existent. Small, stylish and portable, the Airfree Onix 3000 comes with a 2-Year Manufacturer's Limited Warranty.

Airfree air purifiers are subject to Minimum Advertised Pricing (MAP).

The strawberry test below shows clearly the difference an Airfree Air Purifier makes in controlling mold.

Airfree's patented ceramic core technology (called the Thermodynamic Sterilizing System or TSS™) has undergone over 20 independent tests by world-renowned institutions and ISO 17025 laboratories in eight countries, including the USA, Sweden and Germany. These independent tests prove the efficacy of Airfree in its ability to destroy microorganisms that pass through the TSS heated ceramic core, no matter how small, resistant or dangerous they might be.

These tests also prove what may be most important for consumers – the level of microorganism and pollutant reduction actually achieved in the room. Airfree air purifiers do not work like and cannot be measured in the same way as ordinary air purifiers. While Airfree begins working within a few minutes of being plugged in (which begins the process of bringing relief to allergy and asthma sufferers), it will take 2 to 3 weeks for Airfree to reach maximum performance of reducing an average of 85% to 97% of airborne microorganisms and pollutants within a room. This performance level is not an idle claim, but has been proven through numerous tests conducted in real working and living conditions, like hospitals, hotel rooms, offices, and laboratories, not over a period of minutes, but of weeks and months.

Benefits of Airfree Air Purifiers:

  • No Ozone!
    • According to the Environmental Protection Agency (EPA), ozone is a toxic gas that can trigger asthma and destroy lung tissue.
    • Airfree air purifiers generate no dangerous emissions – no ozone, no ions, no UV light.
    • In fact, independent laboratory tests conducted in Sweden demonstrate that Airfree actually reduces ozone by 26%.
  • Clean!
    • No need to change dirty, contaminated filters or fan blades, which can trigger allergic reaction in sensitized individuals.
  • Silent!
    • Airfree emits NO noise – no fans, no motors, just quiet.
  • Economical!
    • Airfree is virtually maintenance free ‐ nothing to replace, no moving parts.
    • No filters or UV lamps to replace! Replacement parts for other air purifiers can cost $60-$100 a year, or more.
    • Airfree uses less electricity than a 50W light bulb, costing only pennies a day to operate.
  • Efficient!
    • Airfree's exclusive TSS technology uses combustion to efficiently incinerate and destroy airborne microorganisms.
    • Airfree's effectiveness has been well tested by universities and over 20 respected ISO 17025 and other independent laboratories in 8 countries.
  • Easy to install and use!
    • Just place Airfree on the floor and plug it into the nearest outlet. No need for constant maintenance or cleaning.
  • Safe!
    • Airfree is the only technology proven to reduce ozone while simultaneously destroying microorganisms
    • Airfree is not hot to the touch, and is safe to operate continuously.
    • Electrical safety is assured with:
      • CE and UL approvals.
      • Airfree's automatic shut-off of the heated ceramic core if an irregularity is detected, such as blockage of an air intake port, or tilted placement of the device, or if ambient temperature reaches 95°F (35°C). In this event, you will be alerted by the unit's red blinking light.
    • Airfree sterilizes air using heat alone. No fiber-glass filters, triclosan-coated paper or any type of material harmful to you or the environment when discarded.
  • Faster Performance!
    • Microorganism reduction begins just 15 minutes after Airfree is plugged in.
  • Durable!
    • Airfree's smart, long-lasting design has no moving parts, resulting in virtually no wear and tear.
  • State of the art!
    • Airfree's automatic warning sensor alerts users if the unit is improperly placed or malfunctioning.
    • Energy-saving feature "shuts off" Airfree's ceramic core for a few minutes when it reaches the optimal temperature for air convection or if ambient room temperature reaches 95°F. The unit continues sterilizing air during this time.
