Optimal air for extra-large spaces

Filters the air in a 674 ft² space in about 12.5 min² (4.8x an hour, based on AHAM recommended removal rate) or up to 3,235 ft² in one hour on high speed to effectively lower particle levels and maintain a comfortable environment in spaces like your oversized family room, basement and open concept areas.

Blueair Protect with dramatization of SpiralAir technology
More clean air to every corner of the room

Unlike other air purifiers that only push clean air to a small part of the room, our patent-pending SpiralAir™ outlets are uniquely engineered to deliver 360°, omnidirectional airflow - quickly circulating so you can breathe clean air wherever you are.

Advanced sensors & clean air ETA

Advanced sensors keep track of the levels of coarse particles (PM10) like dust, pollen, and ash and fine particles (PM2.5 and PM1) like smoke. If pollutant levels creep up, the Blueair app will track the air purifier's progress with real-time 'ETA' updates until air is clean.

Blueair Example of RFID chip in Blueair SmartFilter technology

The SmartFilter has a smart RFID chip that proactively monitors real-time usage and accurately judges when you need to replace it, with a maximum of 1-year lifespan.

Clean air to welcome you home

Innovative 'Welcome Home' feature uses geo-fencing technology to put the air purifier into standby mode when you leave the house, and turn back on again as you approach home.

Feature can only be enjoyed with the Blueair app.

What technology is used in the Protect air purifiers?

The technology used in Protect air purifiers is the combination of the HEPASilent Ultra™, Germshield™ and SpiralAir technologies™.

What is HEPASilent Ultra™?

HEPASilent Ultra™ is a combination of mechanical and electrostatic filtration, which ensures particle removal and gas reduction. Compared to the HEPASilent technology (used with Blueair Classic and JOY air purifiers), the new Ultra™ technology combines an optimised fan system, engineered in Sweden by Blueair, optimised electrostatic filtration and an improved filter.

What is Germshield™?

Germ growth may happen when temperature and humidity levels are high. The Germshield™ functionality is designed to prevent germ growth inside the air purifier when the air purifier is not in use.

What are the different settings and features available with Protect air purifiers?

Three airflow speeds, Automode, Germshield™, Connection with Blueair app (see WiFi and Blueair app FAQ for more information), Indoor air quality indications on the air purifier, Filter change indicator.

What filter can be used with the Protect air purifier?

The Blueair SmartFilter is the only filter available for the Protect air purifiers.

It consists of two filters attached by a strap at the top. Each filter has a particle filter media and activated carbon. The Protect air purifiers also have two pre-filters that can be cleaned with a dust cloth or by using the soft brush of a vacuum cleaner.
