QuietPure Whisper Bedroom Air Purifier by Aerus


The Blue by Blueair 211+ Air Purifier makes air purification simple with its one-button activation and it offers the highest filtration capacity of any air purifier in its class. The Blue features a 360-degree air intake on the bottom of the unit, providing efficient air purification wherever you need it. It removes smog, dust, pollen and other particles from the air, leaving the air in your home clean to breathe. The Blue features a single control button that enables users to easily choose between three speed settings. It cleans the air in rooms up to 540 square feet and it provides 5 air changes per hour. Choose from 5 interchangeable fabric color options that were designed to fit your style—Diva Blue, Buff Yellow, Crystal Pink, Dark Shadow and Lunar Rock. The colored fabric also acts as a pre-filter, catching large particles and helping to extend the life of the main filter. The pre-filters are also washable and they can be vacuumed if they should require cleaning. The Blue comes standard with one combination particle and carbon filter—the carbon helps with the removal of odors and VOCs. As an added bonus, the Blue and all of its components are recyclable, so you can feel good about recycling the filters when you're finished with them instead of just throwing them in the trash. The Blue 211+ includes a manufacturer's limited 5-year warranty.
