Airfree Onix 3000 Review


Filterless and offering an amazing cost-to-coverage ratio, this model uses proprietary technology to destroy microorganisms with ultra-high heat before returning air into rooms up to 650 square feet.

For a fairly low price, the Airfree Onix 3000 (starting at $266, Amazon) boasts coverage for areas up to 650 square feet; ease of use (just plug it in and walk away); low operating costs; and eco-friendly technology for attacking germs, mold, pollen, mildew, and other allergy offenders lurking in the air.

Airfree uses a patented Thermodynamic Sterilizing System said to remove 99.99 percent of microorganisms from the air. Essentially, air is drawn into the unit by convection, then subjected to 400-degree heat, which immediately incinerates any microorganisms present. The cleansed air is cooled and sent back out into the room. The process is pretty safe and simple, but not without its flaws.

An expert review on the retail site Allergy Buyers Club notes one big drawback of the purification process: Because it targets organic pollutants and uses no fan or filters, it doesn't combat chemical pollutants or odors caused by these sorts of substances. Also, there’s no “turbo” switch here. It takes a recommended seven to 10 days of continuous usage, if not a month, to get optimal results out of this air purifier. Good thing it's silent and relatively small, with a pod-like design that helps it blend into the background. A blue “nightlight” on top keeps users from tripping over it in the dark.

Perhaps not surprisingly, given the novelty of Airfree's TSS technology, user reviews for the Airfree Onix 3000 are more than a little mixed. Many negative reviews onAmazon come from buyers who insist they can't even tell if the air purifier is working. And it does seem as if more than a few of the reviewed units were duds. On the other hand, positive user reviews on Amazon are effusive, and the Airfree Onix 3000 has earned an average of 4.6 out 5 stars from nearly 60 Allergy Buyers Club customers. Some reviewers say they’ve seen dramatic improvements in their allergy symptoms and breathing overall.
