Filters

Progressive, three-in-one filters:

For a more effective air purification, there are three different filters in each Blueair filter. This unique filtration process can remove six times more particles than classic filters. Most of these filters are thinner and made of fibers of the same size.
On the other hand, the Blueair filters are made of millions of thin fibers, ultra-thin fibers and 0.1 micron fibers, hence the name progressive. The first layer removes the biggest particles, while the two others removes smaller ones, such as pollens, virus, bacteria and cigarette smoke.
