AirfreeP1000 Filterless Silent Air Purifier for Home I Requires No Filter, Fan, or Humidifier, Covers 450 sq ft - White

The Airfree website has documentation and videos about the science and testing done on the airfree devices. As a layperson, the theory behind it is solid too. A ceramic chamber heats air to 400 degrees where basically anything organic will burn. Natural convection will pull air and any viruses/bacteria/fungus through the chamber, burning any said organisms. However, unlike a filtering air purifier, there's no filter media to visibly show dust or smoke collected or filtered. So, there's a lot of skeptics on this product. I gave one unit to my brother, who said after running the airfree in his basement bathroom that it's the first time he's not smelled mold in the bathroom (yes, I've told my brother that he shouldn't run it directly inside the bathroom).The skeptics and people who don't read through or understand the theory behind the product will think that the airfree collects viruses or bacteria or fungi spores inside the unit and that moving the unit to another unit will release those things back in the air or something. No, the airfree takes a long time to process the air in a room because it relies on convection and not a fan to pull air through the heating chamber. There is a lot of air in a room which is why it'll take a while to start reducing airborne contaminants. Because the airfree is only killing airborne spores if you move it out of the room then the mold that is still living in the wall producing said spores will just continue spreading those spores, they just won't be killed by the airfree.Just like with any air purifier, this is only a piece of the puzzle. Take care of any contaminants (mold, decay, messes, etc), keep your areas as clean as possible and the air purifier will help in maintaining the air quality.I recommend this product, especially for a moldy bathroom that you haven't remedied yet.

This air purifier is IMPOSSIBLY good!!! I am floored by the magic show that unfolded in my home today. Our daughter had a ferret that free ranged in part of our house and as a result of many years of the little friend soiling on the laminate flooring, it stinks (a lot!) and has to be replaced. I have been quite grumpy for years about the floors (bad smell, lovely ferret) but we were committed to not replacing them until the ferret died (because she would do the same thing to the new floors). She recently passed away and we are going to be replacing the floor any day. In the mean time, late the other night, I was in a pretty bad mood because of the smell and decided to order this little miracle worker.It arrived on my doorstep today and all I needed to do was plug it in (easiest machine to operate, ever). Tonight, about 8 hours later, I am breathing the freshest, loveliest air this house has ever known and, as a result, am in a really, really great mood. The stink is gone!!!! The floors are still ruined and need to be replaced, but this air purifier is so shockingly effective that it is cleaning the air before any lingering memory of our dearly departed ferret reaches my nose.I cannot believe I waited this long to order this. I am kicking myself to know now that for all the years that we had that ferret, we could have been breathing pristine, fresh, air. The difference in our air quality is so drastic. We could have had this years ago!!!I LOVE this air purifier - anyone who loves their pets but hates the smell will find a new lease on life with the AirFree P1000 Filterless Air Purifier. I wish I could post a before and after smell :) nothing short of miraculous.

We could smell mold when we entered our place. No longer noticing the smell. Seems to be doing the job. Like the idea of not having to replace a filter. Heat comes off the unit but hard to know what the impact will be.

I was in the mood to throw money around when I first bought this 2.5 years ago. Just moved into a new home and had to come back and order another, to cover more space. These things actually work. I can tell the difference because the first few days I kept moving my one existing one to different parts of the house, trying to figure out where it might be useful. I had a mold problem in my previous place, but nothing noticeable here. Well I was wrong. It is noticeable when you have a basis for comparison. The part of the house that has this thing in it always smells nicer and has less of a musty feel than any other part of the house.I still use an air purifier for getting rid of dust and smells like cooking, perfume, etc. This has a very specific purpose. It doesn't remove large particles from the air like a purifier. It sanitizes the air by killing living organisms, like mold and dust mites. I also have a Rabbit Air that cleans dust and odors from the air.Speaking of odors, this does off-gas for awhile. I think it was 2 weeks before I stopped smelling burnt plastic type smells from it. But that was years ago, and have been benefiting from it greatly since I got past that pesky period. Well worth the purchase. I'm so glad I took the chance on a technology that seemed absurd, but actually works.

Why did you pick this product vs others?:I liked the idea of not having to change filters. I used to own the Brookstone Ionic, which breeze didn't have filters either. You would just pull out the center piece and wipe it down and it was obviously attracting lots of dust. You could also tell when cleaning the house. I have birds, which are very dusty and the house stayed much cleaner. This is more like a paperweight that you waste electricity on. Their is no improvement in the cleaning and when I wipe it down, very little comes off. Do NOT waste your money. I'm super disappointed
