Three layers of ultra-advanced filtration

An outer fabric washable pre-filter starts the process by removing larger particles. This also extends the life of the main filter.


The main particle filter removes everything from pollen, dust and pet dander to viruses and bacteria.


Then a layer of activated carbon goes to work, ridding households of light odors from pets, cooking and smoking.

Maximum filtration. Minimum noise.

Only Blueair air purifiers use HEPASilent™ technology which provides maximum filtration with minimum noise. This dual filtration technology pioneered by Blueair combines electrostatic charging of particles and mechanical filtration using a unique filter design. Blueair air purifiers, therefore, produce more² clean air faster, cleaning your air quicker and much more quietly³ than traditional HEPA air purifiers.

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.

Pre-filter for extended filter life

While the colorful fabric of the washable pre-filter looks great, it also extends the life of its primary filter by catching large particles. Its fabric can be vaccummed or put in a washing machine for easy cleaning.

Blueair AQI icon
Multi-status air quality indicator

An AQI, or air quality indicator, uses an LED to display colors for good, moderate, or poor based on the amount of fine, PM2.5, particles an integrated particle sensor finds in your space.

How does this model differ from the Blue 411?

Building on the original Blue Pure 411 model's functional design and performance efficiency, the 411 Auto features new premium pre-filters, integrated particle sensor, Auto mode setting, and LED air quality display. The new model also features a slightly increased recommended room size (up to 190 ft²), at the same compact size as the original.

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.

What is the Air Quality Indicator showing?

The integrated particle sensor measures the concentration of fine particles (PM2.5) in your indoor air. The LED air quality indicator (AQI) display uses a three-color scale to represent current PM2.5 concentrations as good (blue), moderate (yellow), or polluted (red).

What are the settings on this model?

The lights on the LED touch-button indicate the selected fan speed setting. Touch once to set to Auto mode (all three LED lights lit). Press twice for the lowest fan speed (top right LED lit), three times for medium (bottom LED lit), four times for high (top left LED lit). Press a fifth time to turn the air purifier off (no LEDs lit).


You'll notice that after about 5 seconds, the LED lights on the touch-button dim down to 0% brightness. To change speed settings, you'll need to tap the button once to 'wake up' the air purifier and then cycle through settings.

¹Based on third-party testing of removal rate of fine particles according to GB/T18801-2015 standard and pollen removal rate according to AHAM AC/1-2019 standard. According to AHAM, air changes per hour (ACH) is the measure of the outside air volume added to a space divided by the volume of that space over a set amount of time.


²Based on testing of particle CADR (GB/T18801-2015, particle size >0.3µm) in a HEPASilentTM /HEPASilent UltraTM unit at the same fan speed, compared to using H13 true HEPA filtration in the same unit.
