AirFree onix 3000

I was sent an Airfree Onix 3000 air purifier for review. There is an affiliate link in this post. All opinions are my own.

I’ve had allergies since I was a little kid. I knew that getting a dog is not the best thing for air quality, but I just adore my pugs. I’ve considered air purifiers for a while, but the main thing that held me back was maintenance. I have a hard time remembering when to change my smoke detector batteries, even though it yells at me when they start going bad. I just knew that I would never remember to change a filter every 60 to 90 days in an air purifier.

So, I was really excited to learn that AirFree air purifiers do not require any maintenance. They work similar to how boiling water eliminates microorganisms in the water. Air comes into the air purifier rom the room, is heated to about 400 degrees Celcius, and the temperature sterilizes it. Then the purified air cools from within the device before returning to the room.

The Airfree Onix 3000 is incredibly easy to use. You simply plug it in! It is literally silent while running, so it’s easy to forget it is even there. Airfree air purifiers send between 12,000 and 20,000 liters of air through the device every hour (depending on the model), so it works very quickly.

Having cleaner air helps reduce the spread of mold. To show this, Airfree ran a test on strawberries. This video is pretty mind-blowing!

I feel particularly good about how it can reduce mold. Our house is built into the side of a hill, and only has one window that opens, and two doors for the entire house. As a result, even if we leave the screen door open, and the window, there just isn’t great air circulation, and being nearly at basement-level, we deal with some dampness. I feel better knowing that the Airfree Onix 3000 is working to improve the quality of our air all the time, and takes no work to maintain it from me. It also has a nightlight option. It has a blue light that can adjust in intensity by tapping just above the logo on the side of the Onix. It took me a while to catch this because it feels like plain, flat plastic but there is a sensor in there to detect your taps!

    I had major mold issues in my home after Hurricane Irma and moisture got into my home. I really need an air purifier like this to safeguard my home, especially with 2 young children.

  • Sarah L

    That looks like a great invention. I have some mold that just won’t go away.

  • John Smith

    The strawberry mold test certainly makes a compelling case!

  • ellen beck

    I have to run a dehumidifier in some seasons, so know our house could use this. We live in an older home with an very old basement. I like how this doesnt need filters changed, I cant remember that either. The strawberry test is amazing!

  • Peggy Nunn

    I can’t remember to change the filters either. I would like that one. I will have to check it out. thank you for the review.

  • Dandi D

    My husband and son both have allergies and asthma, so this would be helpful to have!

  • Barrie

    I love air purifiers but changing their filters are expensive and hard to remember to do. I love the idea of an air purifier that doesn’t need a filter to change! It looks wonderful although I think I’d need a larger sized one.

  • Dana Rodriguez

    I have allergies so this would be so nice to own!

  • Melissa Storms

    It is a definite plus not having to remember to change filters. I have too much to remember already.

  • Lauryn R

    This sounds like an amazing air purifier that actually works! We live in a very humid state, so we could definitely use something like this in our home. Thanks for sharing!

  • shannon fowler

    This sounds awesome. I have horrible allergies where we live. This seems like it would be really beneficial.

  • MeMe R

    I have brought many air purifiers over the year only to be disappointed. They either really do require maintenance or don’t do the stellar job that they are touted to do. I hope this one does the job. I have “freaky dog nose” as my husband says and I also have a stomach issue called gastroparesis which puts me in the hospital, and odors will make me vomit, then kick that off. I am going to look into this one.

  • Rosie

    I’ve been considering getting an air purifier. I’m in a complex that the air is shared from other units, and it can be bad. I want to consider this one!

  • Darcy Koch

    I could benefit using one. In our basement we often have mold. Then, the caulking around out bathtub gets so moldy. I don’t think there is enough fresh air circulating. I hate damp smells.
