Selected as Wirecutter's top air purifier
After an independent review by Wirecutter's experts, Blue Pure 411 was selected as Wirecutter's top air purifier camp. Wirecutter said in the "Top Air Purifier" feature article that this model is "small, efficient and attractive."

Three-stage progressive filter
The front fabric filter provides the first layer of protection and can capture large particles such as pet hair and dust, thereby extending the life of the main filter. The particle + activated carbon composite filter is an activated carbon layer, which can filter out light and peculiar smells caused by pets, cooking and smoking at home, and the main particle filter can be used to remove suspended particles in the air, such as pollen, dust, and pet skin Crumbs etc.

The mystery behind the super filtration performance
We combine static electricity and mechanical filtration technology to bring our original HEPASilent filtration technology, which makes us unique in the industry. This combination of technologies allows us to use a lower-density filter material. Compared with the traditional HEPA filter, the air pressure required is lower, and there is no loss of performance, so as to realize the ultra-quiet operation of the air purifier and more energy saving .

This air purifier was awarded the "Mute Certification Mark" and is known as one of the most excellent air purifiers in the category. In the low wind speed mode, the noise level is equivalent to whispering (17 dB), while in the high wind speed mode, the noise level is only equivalent to a quiet library (46 dB).
