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 'Warranty' 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.
