Filters the air at the industry-recommended rate of 4.8x an hour (or about every 12,5 minutes) in a 620 ft² room to effectively lower particle levels and maintain a comfortable environment in open-concept floor plans, studios & basements.
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.
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.
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.
Match to your space with six fabric pre-filter colors (Dark Shadow and Diva Blue included). Or, for a Scandinavian look, go without a pre-filter to show off the sleek white-mesh frame.
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).
Unlike some air purifiers with strict rules for placement, the Blue Pure 121 uses a 360-degree air intake, meaning you can place it almost anywhere in the room without compromising performance.
ENERGY STAR rated for best-in-class energy efficiency (31-61 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.
The colorful fabric doubles as a pre-filter, catching large particles and extending the life of the primary filter - vacuum the fabric or toss it in the washing machine whenever it needs cleaning.
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.

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.
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.
