The Airfree Onix 3000 air sterilizer features totally-silent operation and kills 99.99% of airborne microorganisms using the patented Airfree sterilizer technology. The Onix 3000 moves air through natural air convection, the way that hot air balloons move air; hot air rises. The Onix's patented ceramic core heats the air up to 400°F, sterilizing it and eliminating harmful ozone, fungus, bacteria, allergens, viruses, mold, dust and more. The air is then cooled and returned back into the room, providing safe air for you and your family to breathe. The Airfree Onix 3000 is energy-efficient, using little watts like a small light bulb. It does not require maintenance or filters, so you don't have to worry about spending money on expensive replacement filters.

  • The Onix 3000 is designed to use on the floor, but not on thick carpeting, in a vertical upright position, away from curtains or blinds that could obstruct airflow.
  • Do not use the air sterilizer on its side, under furniture or with its bottom or top air outlets blocked, thus preventing air from flowing in and sterilized, clean air from flowing out. If any of the above occurs, the Thermo-dynamic sterilizing ceramic core will be disconnect and the unit will not work properly. After about 1 minute, the anti-stress light will start to blink to call for attention, indicating poor installation or malfunctioning. After a few seconds of the unit working properly, the anti-stress light will stop blinking.
  • Always keep the air sterilizer turned on.
  • Use for at least 10 days to see a 70 - 90% reduction in microorganisms. You may see results after 1 week of operation.
  • Install 1 Airfree Onix 3000 air sterilizer per each 650 square foot area with a ceiling height of 8 feet.
  • For the best results, keep the sterilizer plugged in the same room
The Airfree Onix 3000 Air Sterilizer is a great choice for someone that is looking to destroy mold spores, fungi, bacteria, viruses and neutralize allergens in their home or office space. It is also one of the only air cleaners on the market that reduces the level of ozone in the air, and of course, it does not produce any ozone or ions. The Onix is not a solution for reducing the amount of dust in a home or for removing airborne gases or chemicals. 
As a great bonus, the Aifree Onix 3000 does not require any maintenance or filters, saving you money on annual replacement costs!

  • Kills pathogens including mold spores, bacteria, viruses and pet dander with a 99.99% efficacy
  • Silent operation— perfect for use in an office, home or bedroom
  • User-friendly operation: turn the Onix on and it is ready to go
  • No filters and does not require maintenance; a money-saving advantage over other air purifiers that require filters
  • Helps to stop food from developing mildew so it stays fresher longer
  • Independent tests show that it will reduce ozone that is present in the air and it can reduce ozone by 26% with each pass of air through the unit
  • Lightweight: At 3.3 lbs. it is extremely lightweight and easy to carry
  • Safe to use with its automatic shut-off feature that prevents overheating if the air intake or outlet are blocked, if the unit is tilted, near a heater or too close to a wall. A red blinking light will go off to notify the user if this occurs.
  • The Airfree air sterilizer does not dry out the air or have an affect on a room's humidity level
  • The blue night light features a dimmer that enables users to adjust the brightness or turn it off


  • It reduces ozone by 26% but it does not do much for removing general gases, chemicals, and odors because it does not have carbon gas filters
  • Since the Onix air sterilizer does not have a fan, it moves air through convection. This slow process does not produce immediate results, users will see the best results over a 21-30 day period with continuous use. Although, test results show a 70% - 90% reduction of microorganisms in 10 days.
  • Since the Airfree Onix 3000 does not use filters, it will not reduce the amount of particles that are in the air. However, it will neutralize the part of the particle that can cause allergic reactions.
  • Plastic off-gassing can occur the first day or two when the unit is first turned on due to the new plastic and heat. The unit will stop off-gassing after 24 - 72 hours of continuous use.
