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.

Noise has always been a big problem for commercial air purifiers, and HisoAir has been deeply involved in the field of commercial air purifiers. To reduce the noise of air purifiers, HisoAir’s R&D team has conducted hundreds of comprehensive tests on motors, fans, materials, structures and frames, and finally developed the Decibel Cancellation™ technology. Now we can proudly say that no air purifier on the market can be as quiet as our product!

How do Hisoair air purifiers work? that uses free radicals—the same radicals used to destroy cancer cells—to break down pollutants at a molecular level, including viruses, bacteria, mold, ozone, allergens, and chemicals. with high-efficiency filtration and air quality sensors, Hisoair air purifiers can capture particles found in smoke, while detecting and destroying pollutants 1000 times smaller than the standard filters must meet to qualify as HEPA.

This unique of filtration technology effectively removes 99.97% of airborne particles down to 0.1 micron, trapping even the smallest viruses and microplastics in addition to dust, pollen, pet dander, bacteria and smoke. Activated carbon in our filters then removes odors, gases and VOC’s.
