Blueair F100 103 Replacement Filter

This filter is designed to fit the Blueair 103 model air purifier and employs Blueairs patented HEPASilent technology to provide comprehensive filtration for your indoor air.

HEPASilent filters work in conjunction with an ionizer to provide the most effective filtration on the market. As air is drawn into the machine, an ionizer charges the air with negative ions and prepares it for the actual filter system. The freshly ionized air then continues on to the 3-stage polypropylene filter medium, which is comprised of millions of ultra-thin electrostatically charged fibers. When the ionized particles pass through the filter, the pollutants present in the air are forced to adhere to the fibers. After being filtered of 99.97% of airborne pollutants down to 0.1 microns in size, air is gently released back into the room.
