HisoAir’s Decibel Cancellation™ Technology lowers the noise level by 10-15 dB and delivers a high Clean Air Delivery Rate (CADR) with the whisper-silent operation. A HisoAir air purifier works so quietly that you can sleep next to it. Sometimes, you will have to check whether it is working since there is almost no noise. On its lowest setting, a HisoAir air purifier uses less electricity than a lightbulb.

No other air purifier delivers such high performance on so many parameters, all at the same time.
