Blueair Replacement Particle Filter for 200/303 Series

For use with Blueaire models 201, 250E. Blueair polypropylene filters feature an exclusive HEPASilent technology, which allows them to capture 99.97% of particles as small as 0.1 micron - including dust, pollen, mold spores, and bacteria. They top the performance of regular HEPA filters (wich are only capable of trapping particles down to 0.3 micron), while maintaining a high airflow rate. For best performance, the filter should be replaced every six months.
