Blue Pure 221
Filters the air at the industry-recommended rate of 5x an hour (or about every 12 minutes) in a 50 m² room to effectively lower particle levels and maintain a comfortable environment in large living rooms, family rooms & playrooms.
Independently reviewed by the experts at Consumer Reports and recommended as a top air purifier.
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.
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.
Customizable pre-filters
Adapts to your space with multiple color options. The colorful fabric doubles as a pre-filter, catching large particles and extending the life of the primary filter. Simply vacuum the fabric or toss it in the washing machine whenever it needs cleaning. Go without the pre-filter altogether for a clean Scandinavian look.
Sleep without disruption
Noise-levels are no louder than a whisper on the lowest speed (32 dB) and equivalent to the noise level of rainfall on the highest setting (56 dB).
Simple to place
Unlike some air purifiers with strict rules for placement, the Blue Pure 221 uses a 360-degree air intake, meaning you can place it almost anywhere in the room without compromising performance.
Low energy consumption
ENERGY STAR rated for best-in-class energy efficiency (30-61 W) - certified room air purifiers are 40% more energy-efficient than standard models, so you can run your air purifier 24 hours a day without concern.
Forget about adjusting settings and knobs - a single button controls it all and lets you know when it's time to replace the filter.
The built-in LED warning system glows red when it's time for a change. For optimal performance, we recommend replacing every 6 months.
After about 7 seconds, the LED light will automatically dim to 10% brightness.

Guarantee clean air for years to come with extended warranty coverage when you register your air purifier.

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