The starters

8.4 x 11.8 x 8.4 in
(21.3 x 30 x 21.3 cm)
Airfree Fit800 weight
1.5 lb (0.7 kg)

A rare wall-mountable air purifier, Airfree Fit800 curvy bottom design is shaped to be small and lightweight at only 8.4 x 11.8 x 8.4 in/ 1.5 lb weight. Mountable to the wall, the air purifier does not take up any room space, therefore, it is technically child-proof as it is not reachable. A basic plug and play unit with no control whatsoever, Airfree Fit800 comes standard with passive safety features such as Thermistor safety sensors, thermal fuse, varistor, and current limiting fuse. It is also CARB certified to be ozone free and ion free.

Purifying coverage
180 sq. ft. (17 m2)
Airfree Fit800 fanspeed
Airfree Fit800 has the poorest purifying coverage within its range at only 180 sq. ft. On top of that its "sterilization" purification method is based on a gradual improvement to the air that requires Fit800 to be running 24x7 and even then it could take days to complete the whole purification cycle.

Patented Thermodynamic TSS Technology

^ Airfree Fit800 purification technology
As mentioned earlier, Airfree Fit800's Patented Thermodynamic TSS technology would absorb liters of water and heat the air over 400°F (200°C), destroying anything that stands within before cooling it down inside so only sterilized air will be flown out. The eco-friendly method that requires no filters/ UV light and will remove pollen, dust mites, bacteria, allergens, pet dander, tobacco plus odors.

Silent operation is what Airfree Fit800 outshine most conventional air purifier as it does not utilize any fan in the process. Ideal in a living hall, bedroom or even meeting room. The 33W power consumption is low but does keep in mind that it is a requirement to keep the air purifier going 24x7. A plus point is Airfree Fit800 comes with an energy-saving mode where it will automatically shut off its ceramic core once it reaches a certain purification temperature.

Airfree Fit800 is not cheap given its weak purification and applicable area. You do save up a lot in long-run as there is no annual filter replacement cost moving forward. Just pay for the unit and that's about it.

More on Airfree Fit800 Filterless

One of the few rare wall-mounted air purifier that looks like an air freshener, Airfree Fit800 Filterless is 100% an air purifier that is unique on its own. With a bloated curvy body that provides airflow circulation at the front, Airfree Fit800 Filterless is not only light and unobtrusive, it is also mountable so it will not compromise any room space. Although the plastic feels cheap to a certain extent, it is very safe with zero off-gassings and ozone-free.

Airflow performance and applicable area

With its own purifying technology, Airfree Fit800 Filterless filtration and airflow performance are not at an abysmal level, but it’s certainly far from great either. At 17 m2 (180 sq. ft.) purifying range (on paper), Airfree Fit800 Filterless should be able to cover common pollutants such as dust, mold, pollen but do not expect the same results as other HEPA-type air purifiers.

Final thoughts on Airfree Fit800 Filterless

To sum it up, Airfree Fit800 Filterless is a maintenance-free air purifier that is very compact but pricey with slow purification. If you don’t need A) very compact air purifier and B) maintenance-free, there will be plenty of options in the market.
