Large spaces, lower particle levels

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 viruses and bacteria.


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

Blueair 211+ coming apart to show  3 layers of filtration
Maximum filtration. Minimum noise.

Only Blueair air purifiers use HEPASilent™ technology which provides maximum filtration with minimum noise. This dual filtration technology pioneered by Blueair combines electrostatic charging of particles and mechanical filtration using a unique filter design. Blueair air purifiers, therefore, produce more² clean air faster, cleaning your air quicker and much more quietly³ than traditional HEPA air purifiers.

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.

How does this model differ from the 211+ Auto?

The upgraded, Auto version of the Blue Pure 211+ model features an integrated particle sensor, intuitive Auto mode setting, and 3-color LED air quality indicator. 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).
