My Overall #1 Rated Pick
Updated On January 10, 2023
My overall top pick for the best filterless air purifer goes to the P2000 by AirFree. This purifier cleans the air differently than the average purifier in that it super-heats the air killing microbes and removing harmful particles. After heating the air, it goes into a cooling chamber to bring the temperature and humidity down. It uses very little energy and it also comes with a blue night light.

What Is A Filterless Air Purifier?
Let's face it: home air purifiers can be expensive. Home air purifiers can range from $100, and all the way up to $400. But that's not where it ends.
You are forced to buy endless filters from the manufacturer, and you have to do continuous maintenance such as cleaning the fan. However, most homeowners don't know that there are other options.
There are other well-known technologies that can purify the air as good as filtered air purifiers, and in some cases even better. The two main filterless air purification methods are negative ionization as well as TSS technology.
'Negative Ion' Filterless Air Purifiers
One of the most widely used filterless technologies is called a negative ionizer. Negative air ions were discovered over 100 years ago, and are widely used for air cleaning.
This air purifier sends negative ions into the air, which are basically molecules that have been charged with electricity. These negative ions latch onto bacteria and viruses, as well as other air pollutants. The ions cause the hazardous air pollutants to become heavy, and they sink to the floor or onto other hard surfaces.
And when you do your routine home cleaning, these pollutants are removed from the hard surfaces.

TSS Filterless Technology
The second filterless method I would like to discuss is TSS technology, and TSS stands for thermodynamic sterilization.
The basic concept is that it heats up the air which kills microbes and removes harmful pollutants. It works similar to boiling water in order to kill bacteria.
After the air has been sterilized, it goes into a cooling chamber, and then sends this sterilized (and cooled) air back into the room.
The only company (as far as I know) that is selling air purifiers based on TSS is called AirFree.
