If you’ve dealt with air purifiers before, you probably know that you will need to replace their filters now and then to ensure that the unit’s performance remains above board. The maintenance costs that come with doing this can sometimes be something you’d prefer not to deal with.

If this sounds like you, then going for a filterless, maintenance-free alternative like the Airfree T800 air purifier might be a viable option that’s worth looking into. For its price, you shouldn’t expect it to be the best air purifier around, but if you’re looking for a budget buy that’ll keep your air free of impurities, then it could be the Best Filterless Air Purifier for you.

Why We Like It – Airfree T800

The Airfree T800 is an affordable and easy-to-maintain air purifier that boasts of an awarded design, and the use of patented Airfree technology to keep the air in your house or office clean. The Thermodynamic TSS technology Airfree implemented in its products means that you get to avoid buying replacement filters, or spending too much on electricity costs.

  • No maintenance costs
  • Completely silent operation
  • Easy to use
  • Small room coverage


With a room coverage of only 180 Sq ft, the Airfree T800 Air Purifier is not suitable for large spaces. However, it relies on filterless technology to get its job done and doesn’t have a built-in fan. This makes it completely silent, much like the Airfree tulip. To get rid of mold spores, dust mites, bacteria viruses, and other air contaminants, the unit relies on exclusively patented Thermodynamic TSS technology, which involves the use of heat to destroy microorganisms. It’s the same procedure that the P3000 Airfree Air Purifier also uses, though it is more suited for a larger room size of up to 650 Square Feet.


The Airfree T800 filterless air purifier doesn’t require that much power to cover a room size of 180 sq ft. Just like the Airfree P3000, it only requires about 42 Watts to function, making it a pretty efficient air cleaner. Its filterless technology also contributes to its low energy consumption so if you’re looking for something that will keep your air clean while keeping your energy costs low, then Airfree Air Purifiers are the way to go.


Through the use of patented thermodynamic TSS technology, the T800 Airfree filterless air purifier is also able to reduce ozone levels indoors, keeping you healthier, and allowing you to breathe cleaner, fresh air. The unit is also easily portable, and at a weight of only 1.5 pounds, it’s very lightweight.


A decent 2-year warranty backs the T800 Airfree air purifier, and since it’s also made in Europe, it has very good build quality. Its use of exclusive patented Thermodynamic TSS technology means there are no maintenance costs attached to it, so all you’ll have to do is plug it in and let it work.


Only available in white, the Airfree T800 is a small solution that could help keep the air quality in your room top-notch. Just like the Airfree Iris 3000, it doesn’t have any air quality monitoring features, or support for WiFi so that you can connect it to your phone, but for something worth $100, it’s pretty efficient and will keep your living space free of any harmful air particles and bad odors.

Airfree T800 Wrap Up

The use of heat to rid the air of harmful microorganisms may not be so popular, but the Airfree T800 does a pretty good job at making sure that you’ll be able to enjoy clean air without the noise that other air purifiers with fans produce. Its low energy consumption levels and zero maintenance costs make it perfect for the buyer who is constrained by a tight budget.
