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.²

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.

Can I place the Blue Pure 411 Auto on my desk at the office?

Yes! The Blue Pure 411 Auto is compact and lightweight making it easy to place anywhere including your desk or countertop. However, to get the most out of your air purifier and effectively clean the air you're breathing, an air purifier’s performance should be based on the total square footage the space you will be in – not just the immediately surrounding area. Be sure to purchase based on the total size of the space you'll be in. We offer business solutions for larger office spaces, which you can suggest to your office management to consider. 


Where should I place my Blue Pure 411 Auto?

The Blue Pure 411 Auto is compact and lightweight in size, and sleek in design, making it easy to place anywhere – ideally in a more central, open location of the room you're using it in. This way, it's able to most effectively capture the airborne particles in your space and let out clean, fresh air in return.
