Blueair Air Purifier Replacement Filter, Blue 121 Particle and Activated Carbon Filter

The Blue Pure 121 Particle and Activated Carbon Replacement Filter Protects against both gaseous and particulate contaminates. An activated carbon mesh layer eliminates harmful gaseous pollutants such as volatile organic compounds (VOCs), tobacco smoke, and other odors. In addition, advanced polypropylene filter media removes particle pollutants down to 0.1 microns in size from your indoor air, such as pollen, dust, and pet dander. Using a 360-degree air intake and up to 4 times the filter surface area than competing replacement filters, the Blue Pure 121 Particle and Activated Carbon Filter lasts longer, on average from 6 months to a year. The click-and-change filter is easily removed and replaced and can be put into recycling at the end of its service life.
