Makes a big difference in big spaces

Filters the air in a 550 ft² space in about 12.5 min¹ (4.8x an hour, based on AHAM recommended removal rate) or up to 2,640 ft² in one hour on high speed to effectively lower particle levels and maintain a comfortable environment in large spaces like living rooms, bedrooms and playrooms.

Three layers of
ultra-advanced filtration

An outer fabric washable pre-filter starts the process by removing larger particles. This also extends the life of the main filter.


The main particle filter removes everything from pollen, dust and pet dander to bacteria and viruses.


Then a layer of activated carbon goes to work, ridding households of light odors from pets, cooking and smoking.

Maximum filtration.
Minimum noise.

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.

How does this model differ from the Blue Pure 211+?

The newer model also differs in its slightly larger recommended room size of 550 ft², slightly higher smoke (353 cfm) and pollen (380 cfm) Clean Air Delivery Rate (CADR), as well as lower noise levels (23-56 dB) and energy consumption (4-38 W).

I've replaced my filters, now how do I reset the filter replacement indicator?​

Press and hold down the LED button for 10 seconds to reset the replacement filter indicator. ​​


How do I register for warranty?

To extend the Limited Warranty from one year to two (2) years, simply complete the product registration form in the 'Warranty' section of your customer account, within (60) days of purchase or register through the Blueair mobile app.​

How should I clean the fabric pre-filter?

Vacuum the exterior of the fabric pre-filter to remove dust as often as you'd like. When the pre-filter requires a deeper clean, it can be washed on a gentle, low-temperature cycle in the washing machine. Hang to dry.

Why is my LED yellow?

The LED indicator will turn yellow after 5 months of operation to warn that it's almost time to change the filter. When the indicator light turns red (one month later), it’s time to change the main filter.
