Blue Pure 411 and 411+ Replacement Filters

Blueair logo


To maintain optimum air cleaning performance, the filter in your Blue Pure 411+ or 411 air purifier by Blueair should be replaced every 6 to 12 months. The indicator light on the one-touch button located on the top of your Blue Pure 411 series unit will turn red when it’s time to change the filter.

IMPORTANT: There are two different Blue Pure 411 series air purifiers, the original 411 and the newer 411+ model introduced into Canada in June 2020. The main Particle + Carbon combo filter fits both units. However, the coloured fabric pre-filters are different for each model so be sure to purchase the right one. If the top of your unit unscews to change the filter, you have the older 411. If the cap on the bottom of your unit unscrews to change the filter, you have the newer 411+ model.
