Resilient galvanized steel. Intelligent auto-adapting sensors with boosted smoke and odor removal. Plus, advanced app and voice control. Breathing is believing.
Filters the air in a 775 ft² space in about 12.5 min¹ (4.8x an hour, based on AHAM recommended removal rate) or up to 3,720 ft² in one hour on high speed to effectively lower particle levels and maintain a comfortable environment in extra-large spaces like open floor plans, studios, or basements.
Only Blueair air purifiers use HEPASilent™ dual filtration technology, delivering maximum filtration with minimum noise. This dual filtration technology pioneered by Blueair combines electrostatic charging of particles and mechanical filtration along with a unique filter designed to produce more² clean air, cleaning your air much faster and more quietly³ than traditional HEPA filtration alone.
Helps remove airborne allergens and asthma triggers like 99.99% of pollen⁴, as well as 99.97% of dust, pet dander, mold, and smoke by using the standard particle filter that comes with the Classic 605.
A DualProtection replacement filter is also available for boosted performance against smoke and odors.⁴
Housing made from durable, galvanized steel stands the test of time. Backed by up to 5 years of warranty to guarantee cleaner air for years to come.
Get clean air while you sleep without noise disruption. Operates at a whisper quiet 33 dB on its lowest speed, and no louder than the 62 dB white noise of a floor fan on its highest speed.
Energy-efficient engineering allows this purifier to use less energy than an incandescentl lightbulb on its lowest setting at 15W and up to 100W on high. Confidently run it for quality air 24/7.
Manually check Wi-Fi and filter status. Adjust speed settings at any time, all with a control panel located under a flip-top lid that sleekly blends in with your interior aesthetics.

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 vs same models with only H13 HEPA.
³At similar CADRs, Blueair Protect 7400 series achieved less noise than same models with only H13 HEPA. Noise refers to the dB(A) difference in acoustic power.
⁴Based on testing of noise levels (dB, according to ISO 3743) in a HEPASilentTM /HEPASilent UltraTM unit with the same particle CADR (GB/T18801-2015, particle size >0.3µm), compared to using H13 true HEPA filter in the same unit.
