Designed for extra-large rooms

Filters the air at the industry-recommended rate of 5x an hour (or about every 12 minutes) in a 620 ft² room to effectively lower particle levels and maintain a comfortable environment in open-concept floor plans, studios & basements​.

Optional Extra Protection Filter

The Blue Pure 121 comes standard with a Combination Particle + Carbon filter for light household odors - with the option to upgrade to the Extra Protection Filter with activated coconut carbon pellets to absorb heavy gases, odors, and chemicals from your home environment.

Three-part filtration

A fabric pre-filter offers the first layer of protection, catching large particles and extending the life of the primary filter. The combination Particle + Carbon Filter uses a layer of activated carbon to filter light household odors from pets, cooking, and smoking, while the main particle filter removes airborne particles, like pollen, dust, pet dander, and more.

The secret behind powerful filtration

Our unique combination of electrostatic and mechanical filtration that we call HEPASilent™ filtration technology sets us apart. The combination allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance— resulting in quieter and more energy efficient air purifiers.

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

The 211+ model has many similar features, but the 121 is recommended for an extra larger room size of up to 620 square feet.

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 'My Units' 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 wasehd on a gentle, low temperature cycle in the washing machine.

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.
