Featured in Wirecutter's "The Best Air Purifier" article for "Delivering exceptional performance in an attractive form".

The 3-step filter works with Blueair’s HEPASilent™ filtration technology to remove 99.97% of airborne particles down to 0.1 microns, like pollen, dust, pet dander, mold, bacteria, viruses⁰ and more, while a layer of activated coconut carbon traps light household odors. The one-touch enabled Auto mode setting automatically adjusts to real-time conditions reported by the integrated particle sensor while the LED air quality display updates with one of three colors indicate air quality and indicates when filter change is needed. Cleans the air with noise levels equivalent to a whisper on low (30-52 dB), and ENERGY STAR rated energy efficiency (only 7-35 W).

Change color in seconds with five fabric pre-filters inspired by Scandinavian nature. The pre-filter catches larger particles and extends the life of the primary filter.

Save Money Shopping Online, and Don’t Get Ripped Off 

There are not many official online retailers of Blueair air quality products and unfortunately the internet is full of scams. As a general rule of thumb, if the deal seems too good to be true, it probably is. Cheap cut rate online deals often end up being a used or refurbished unit, which do not come with Blueair's top rated 5 year warranties. Or even worse, you may end up buying a cheap discount air cleaner that doesn’t have the energy efficiency, features or warranties provided by top-rated Blueair HEPASilent and SmokeStop air filtration systems.
