Airfree Onix 3000 Filterless Air Purifier REVIEW

Share on FacebookShare on TwitterShare on Pinterest

Being in the Midwestern part of the U.S., I grew up plagued with respiratory illnesses. I’ve even had more than one doctor diagnose me with asthma because of this. Anyone who lives in this part of the country will tell you that the weather is affectionately referred to as ‘bipolar’ because it just can’t make up its mind with the change of seasons about what it wants to be. Because of this a lot of people in our area have a hard time with illnesses and they hang around longer than they probably should. I’m always concerned that when I get sick that my Grandmother will catch it. We can wash our hands and avoid personal contact as much as possible, but we can’t fight the germs in the air — until now. The Onix 3000 Air Purifier from Airfree is said to remove bacteria and viruses (among other things) in the air so that you can live a healthier life.


The Onix 3000 uses a patented Thermodynamic TSS technology (the same concept as boiling water to destroy microorganisms) to destroy airborne mold, dust mites, bacteria, viruses, pollens, pet dander, tobacco, and other allergens. The air purifier is reported to reduce harmful indoor ozone levels. The technology used to make the Onix 3000 so effective is also very safe. It does not emit ozone, ions, or UV light into your environment. The air purifier is completely silent and doesn’t require any filters or maintenance. It is a low-energy device as it does not use filters or fans. As an added perk, the Onix 3000 comes with an adjustable night light. It covers rooms up to 650ft.

User Experience

I make it an effort to be precise in my product testing and try to find a way to confirm or deny the claims made by product designers. Unfortunately, I did not have an air quality tester at my disposal when I was running the Onix 3000, but I did have one positive test that involved the health of our house. Every January, I venture out west to Las Vegas for CES. I ultimately catch an illness from that trip and I spend about a week in bed after I arrive back home. This year was no different. The exception this time was that I had a minor cold when I came home, my fiance contracted it and the illness spread back to me after it had taken on a new life. It was suddenly bronchitis with a hint of pneumonia that hit me. I was terrified that my grandmother might get sick (she has a weakened immune system). To my surprise, she never did get sick — not even with a little cold. At that point, I was already running the air purifier and I believe that the Onix 3000 is to thank for that.

During the testing period, the Onix 3000 was powered and running continuously for a few weeks. It is completely silent in its operation. There is no whirring or humming because, as described above, the air purifier does not have any fans. The device does take up a decent amount of space on a desktop though. In addition to that, the top — the part that glows blue — gets extremely hot. At one point I used an infrared thermometer to take a temperature reading and got a figure of around 140º F. This is the place where the heat that is supposed to disperse air particles escapes from so I would expect it to be hot, but when planning the placement of the purifier, you should take this into consideration because of the amount of heat that is put out. For example, you wouldn’t want to place it beneath a curtain. You should make sure it’s placed where it can breathe.


The Onix 3000 is a nice option for a quality air purifier. It is quite an investment, but because it actually works in helping with preventing illness, I consider it ‘worth it’. If you are looking for a unique purifier, the Airfree Onix 3000 might be right for you.
