The starters
Like its award-winning design siblings, Airfree Onix 3000 derives straight from it. It has a very compact and lightweight body at 8.4 x 10.4 x 8.4 in and 3.3 lb weight. There are 2 side shells that I suppose it can assist you with the carrying? In any case, you will definitely have no problem carrying and placing it around the house. Air inlet is at the bottom air convection while air outlet is at top. Overall, the solid build quality would have no issue serving you for many years down the road.
Let’s talk about the one and only control. The adjustable anti-stress night light. Right between the 2 side shells, there is a light intensity touch sensor. You can easily adjust the night light brightness or turn it off during day time. Other than the anti-stress light, this air purifier is pretty much a plug and play unit.
Lastly, Let’s talk about passive features. All Airfree air purifiers are CARB certified for ozone-free. There is also thermal fuse, tilt sensor, varistor, current limiting fuse and Thermistor safety sensors.
Airflow, speed, and CADR
What’s inside count
Works similarly to boiling water where microorganisms are destroyed at high temperature. First, the inflow contaminants will be trap inside the TSS ceramic core. The mini-ducts inside the core would begin heating the air over 400°F (200°C). At this point, up to 99.99% of the contaminants are eliminated on the spot and left to cool down inside the machine. The clean air would then be release out without affecting the room temperature. The entire sterilization process is safe, no emissions, ions or new particles generated. In fact, Airfree Onix 3000 help reduces ozone by 26% as tested in Sweden's laboratories.

Airfree Onix 3000 VS the challengers

Airfree Iris 3000
Identical model inside and out. The only difference is Iris 3000 comes with adjustable multi-color stress-free light. Expect little bumps on the pricing.
Airfree P2000
Older, non-black version that is cheaper in price tag. You will lose out on a lower purifying coverage (550 sq. ft.).
