Airfree – The Little Air Purifier That Could


If you want – or because of allergies. need – cleaner air in your home or office you have a few options, starting with a whole house filtration system for a lot of money, or one of those units that sit on the floor that pulls air in with a fan & blows air out after passing through filters, which must be washed or changed, or both.  And then there’s what Airfee offers.

AirfreeAt first glance, their top-of-the-line Airfree Onix 3000 Air Filter looks like it could be R2D2’s baby brother. You quickly notice a couple of things – first, that it has no buttons, switches, knobs or dials – second, it makes no noise and has no fan. It has a gently glowing blue nightlight, and the only way you know it’s working is that the top feels warm to the touch. Otherwise, you might think this is the Emperor’s New Clothes version of an air filter.

Burn, Bacteria, Burn

Unlike almost any other air filter we’ve encountered, the Airfree has no moving parts; doesn’t need to have its filter cleaned or replaced. There are no filters. There are no moving parts. The organic impurities in your indoor air such as viruses, bacteria, mold spores, dust mites, etc, simply circulate through and get incinerated in the device’s ceramic 400° F burn chamber. Poof, they are gone, leaving nothing behind.

The Airfree Onix will handle a room up to 650 square feet. Airfree says it should be left to run all the time. Since there is no fan to force air through the device it can take three to four weeks before the Airfree has really cleaned that room. The device likes to sit on the floor, close to where the bad stuff lurks. There’s a cooling chamber, so after the pathogens are fried, the recirculated air doesn’t add heat to the room.

But Does It Work?

The Airfree Onix 3000 has undergone some pretty rigorous outside testing in venues such as hotel rooms, kitchens, libraries, and laboratories. Airfrees are said to be 85% effective in getting rid of pathogens in the ambient room air, and 99.99% effective at the air output port. While we don’t do our own testing, we’ve been running the Airfree Onix 3000 for about six weeks in our bedroom and I’ve been waking up with far fewer runny noses than before. Price is $299 on Amazon.

Airfree has several other models that work the same way, only cover less square footage; one can be wall-mounted, another’s night light offers a choice of colors from blue to red to green and everything in between. These other models are priced from $159 and up, also on Amazon.
