Blueair Blue Pure 411+ Pre-Filter

The Blueair Blue Pure 411+ Pre-Filter is designed exclusively for the Blue Pure 411+ Air Purifier and help to protect and prolong the life of your purifier. These important pre-filters are manufactured from thousands of premium tightly woven spandex fibers. These fibers help trap and prevent larger dust, dander, and dirt particulates from unnecessary clogging of the primary HEPASilent™ combination filter.

These 411+ pre-filters are easy to care for, just simply vacuum when needed or they can also be tossed in the washing machine whenever needed.

Not only do these Blueair pre-filters play a vital role in the 411+ purification process but they also allow you to customize your unit to match your decor. Choose from six complementary colors – Dark Shadow, Lunar Rock, Crystal Pink, Buff Yellow, Saffron Red, and Diva Blue.
