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.

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).
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.
