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.

How does this model differ from the Blue 411?

The 411 model has many similar features, but the 221 is recommended for a larger room size of up to 50 m².

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, simply complete the product registration form 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.

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.
