Designed specifically for Blue Pure 311i+ Max.
Find the name of your air purifier on the label inside your air purifier.
5 different Scandinavian inspired colors allow you to personalize your air purifier to seamlessly blend into your home by complimenting your interiors.
Stockholm Fog pre-filter color included.
Our washable fabric pre-filters extend the life of primary filters, catching large airborne particles such as dust, lint, pollen, and pet hair. They're colorful too, and can be customized to compliment your space.
A must when changing you main filter! Super easy to install.
So easy to change the pre filter. Plus I like the color choices. Also…it’s washable!
Glad to have the green colour choice. Nice to have a spare for washing, though the product dries very quickly.
Nice to have a second one on hand while laundering the original. Nice color variety.
My Blueair Filter never arrived. The tracker says a label has been attached.
