Designed for large rooms

Clean air at the touch of a button

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.

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.

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.

Blue Pure 211+ Auto was tested in a 13ft³ test chamber. Performance may vary depending upon the room size and location of the device within the room, quantity of particulates in the air, and product use pattern (operational settings and use duration, etc.). Not proven to prevent/reduce transmission of COVID-19.

LED air quality display

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.

One-button design

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.

Easy filter change

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.

How does this model differ from the Blue Pure 211+?

The upgraded, Auto version of the Blue Pure 211+ model features an integrated particle sensor, intuitive Auto mode setting, and 3-color LED air quality indicator. The newer model also differs in its slightly larger recommended room size of 550 ft², slightly higher smoke (353 cfm) and pollen (380 cfm) Clean Air Delivery Rate (CADR), as well as lower noise levels (23-56 dB) and energy consumption (4-38 W).

I've replaced my filters, now how do I reset the filter replacement indicator?​

Press and hold down the LED button for 10 seconds to reset the replacement filter indicator. ​​

How do I register for warranty?

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

How should I clean the fabric pre-filter?

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. Hang to dry.

Why is my LED yellow?

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.
