Blueair Air Purifier Blue 221 For 50 M² Rooms

This combination allows us to use filters that are lower density and require less air pressure than traditional HEPA filters without sacrificing performance – resulting in quieter and more energy efficient air purifiers.Three-Part FiltrationA fabric pre-filter provides the first layer of protection, trapping large particles and extending the life of the primary filter. The combined particulate and charcoal filter uses an activated charcoal layer to filter light household odors from pets, cooking and smoking, while the main particulate filter removes airborne particles such as pollen, dust, pet dander and more.Disturbance-free sleepThe noise level at the lowest levelis no louder than a whisper (32 dB) and is equivalent to the noise level of a rainstorm at the highest level (56 dB).Easy to PlaceUnlike some air purifiers with strict rules for placement, the Blue Pure 221 uses a 360-degree air intake, which means you can place it almost anywhere in the room without compromising performance.Low power consumptionENERGY STAR certified 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 worry.Customizable pre-filtersMatch your room with multiple color options. The colorful fabric acts as a pre-filter, trapping large particles and extending the life of the main filter. Simply vacuum the fabric or throw it in the washing machine when it needs cleaning. For a clean Scandinavian look, you can also skip the pre-filter altogether.One-Button DesignForget about adjusting settings and knobs – a single button controls everything and tells you when it’s time to change the filter.
