The secret behind powerful filtration


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.
