Designed for a life with less cleaning

Patent pending DustMagnet™ technology captures 99%¹ of dust before it settles. A dual air intake and vortex airflow pattern keeps airborne dust particles moving, and an electrostatic charge cluster them together. Once inside, dust particles stick to the charged stainless steel pre-filters just like a magnet​.

What's the difference between the 5210i and 5240i models?

The DustMagnet 5210i has a standard white finish, while the upgraded 5240i model features a premium, light grey textile front, matching grey legs, back panel, and a vegan leather tag.

Is DustMagnet recommended for wildfire smoke?

Our DustMagnet air purifiers with ComboFilters feature integrated activated carbon throughout the particle filter media to remove both fine particles and odors and gases. While DustMagnet models absorb light household gases and odors, they are not designed to accommodate high levels of gases, chemicals and odors that can be present in wildfire smoke.

How is indoor air quality measured?

The integrated particle sensor measures fine particle (PM2.5) levels in your room and updates the color of the air quality indicator (AQI) light on the front of the air purifier based on current conditions. The light will show one of five colors; red (very polluted), orange (slightly polluted), yellow (moderate), green (good), and blue (excellent) to indicate air quality. 

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.​

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

To reset the filter status light, press and hold the airflow speed button for 5 seconds.

Reviews

¹Removal of 99% of airborne dust particles (0.5-3 µm) in 20 min on highest fan speed based on AHAM AC-1 protocol; not applicable to larger particle sizes. 


²Based 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. 


³Comparing CADR performance of Blueair models vs same models with only H13 HEPA. At similar CADRs, Blueair models achieved less noise than same models with only H13 HEPA. Noise refers to the dB(A) difference in acoustic power. Tested on Blue Pure 211+ Auto, DustMagnet™ 5400i, Protect 7400 series. Performance may vary. 


*Tested on E.coli, S. aureus, S. albus, Influenza A (H1N1) and A.niger with a minimum reduction rate of 99.9% in 60min
