Overview; Size and Shape

Blueair keeps the same Swedish design with German touch and comes in an elegant shape and size of 31 inches in height and 20 inches in width followed by 10 inches in depth. This means this purifier occupies very less slim space. Its slimmer size has made it more classy and cool.

 This Blueair pro L purifier is the most advanced purifier in the Pro family. It is the real deal for the highest capacity air purification with the updated version of Pro M. This height size makes him more sizeable than other competitors in the market.

Blueair air purifier has a metal frame from the front which is covering the two fans, used to maximize the fan power. The intake and outlet grills allow the air to get into the unitfrom both sides and flow the air into the room. You will see two fan speeds with a simple button on the top.


Blueair Purifiers are quite famous for their weight but unlike others, Blueair Pro L is quite heavier compared to the rest of the models. It has a total weight of 46 lb which is quite heavier than its competitors.

  • Smoke Stop filter: This filter cleans the air from gaseous pollutants such as cigar smoke and other particles
  • Carbon + Filter: It is used to protect extra air from extra gaseous particles

Blueair devices use a very unique HEPA silent filter by combining both mechanical and electrostatic filtration. Unlike a True HEPA filter, a HEPA silent filter can eliminate particles up to 0.1 microns. All the Blueair filters are recyclable and are antibacterial.
