Blue Pure 211+ Auto
Free Shipping | Free 60-day Return | Up To 2-Year Warranty
Filters the air at the industry-recommended rate of 5x an hour (or about every 12 minutes) in a 540 ft² room to effectively lower particle levels and maintain a comfortable environment in large living rooms, family rooms & playrooms.
The one-touch enabled Auto mode is designed to help you maintain a comfortable home environment. When enabled, the setting automatically adjusts fan speed based on real-time conditions reported by the integrated particle sensor. Stay up to date on your air quality with the LED display; it changes color to indicate good, moderate, or poor.
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.
Verifide by the Association of Home Appliance Manufacturers (AHAM) for performance and Clean Air Delivery Rate (CADR).
Rated as an energy-efficient air purifier by the EPA's ENERGY STAR rating program.
Certified for ozone emissions and electrical safety by the California EPA's Air Resources Board (CARB).
Match to your space with five new premium fabric pre-filter colors (Arctic Trail included) inspired by the natural landscapes of Scandinavia. A hidden compartment in the fabric keeps the power cord hidden out of sight.
The one-touch enabled Auto mode is designed to help you maintain a comfortable environment. When enabled, the air purifier auto-adjusts fan speed based on real-time conditions reported by the integrated particle sensor.
Unlike some air purifiers with strict rules for placement, the Blue Pure 211+ Auto uses a 360-degree air intake, meaning you can place it almost anywhere in the room without compromising performance.
ENERGY STAR certified for best-in-class energy efficiency (4-38 W) - certified room air purifiers are 40% more energy-efficient than standard models.
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.
Stay up to date on the status of your indoor air with the LED air quality indicator (AQI). The display changes color to indicate good, moderate, or poor based on the current concentration of fine particles (PM2.5) measured by the integrated particle sensor.
Forget about adjusting settings and knobs - a single button controls it all and lets you know when it's time to replace the filter. After about 7 seconds, the button's LED light automatically dims to 0% brightness.
The built-in LED warning system glows red when it's time for a change. For optimal performance, we recommend replacing the filter about every 6 months when used 24 hours a day.

To extend the Limited Warranty from one year to two (2) years, simply complete the product registration form in the 'My Units' section of your customer account, within (60) days of purchase or register through the Blueair mobile app.
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 washed 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.
