Airfree Fit800 weight

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.

Airflow, speed, and CADR

Airfree Fit800 coverage
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.

What’s inside count

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.

Highly Recommended

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.
