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.

Say goodnight with night mode

Night mode lulls you to la-la land with noise levels quieter than a whisper, or 25 dB, on low. On high, it's about as disruptive as light conversation at 54 dB.³

How does the Blue Pure Fan and Pure Fan Auto differ from an air purifier?

In addition to filtering out large particles like pollen and dust, the Blue Pure Fan and Pure Fan Auto deliver a gentle stream of cooling air with patented fan technology.

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 five (5) 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.​

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.

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.

Where should I use the Blue Pure Fan?

The Blue Pure Fan and Pure Fan Auto are intended for indoor use. The purifying fans can provide cooling airflow to a nursery, bedroom, office, or study area. ​

Pure Fan efficiently removes large particles from the air approximately twice an hour in a 200sqft room.​
