¹Based on third-party testing of removal rate of fine particles according to GB/T18801-2015 standard and pollen removal rate according to AHAM AC/1-2019 standard. According to AHAM, air changes per hour (ACH) is the measure of the outside air volume added to a space divided by the volume of that space over a set amount of time.  

²Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs same models with only H13 HEPA mechanical filtration. When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration. 

³Based on testing of noise levels (dB, according to ISO 3743) in a HEPASilent™/HEPASilent Ultra™ unit with the same particle CADR (GB/T18801-2015, particle size >0.3µm), compared to using H13 true HEPA filter in the same unit.
