Tres silencieux, la meilleure façon de savoir qu’il fonctionne est de voir la lumière bleue et approcher la main vers celle-ci le purificateur est chaud.

Pas satisfaite

Hard to judge this as I'm not sure what its doing! It's completely quiet, but you can tell it is working because the top is warm. It works by heating the air to 400 degrees, and then cooling it back down. The air in my apartment does seem fresher, and I feel like I can breathe easier when I am sitting next to it. Seems like it works!

Better than expected and have ordered another one already. The difference in my throat and nasal passages is remarkable! This, just after a few days, and look forward to further benefits.

Bought this for my mother who has COPD and asthma. After one week using it she is already taking her emergency puffer less often. The Onix 3000 Filterless Air Purifier is completely silent, which is great. It's small, and very convenient. Also the night light feature is really pretty, really love this product! As always with wayfair, the shipping was really fast too!
