What type of Blueair filter do I need?
Choose a filter type based on the kinds of pollutants (particles and gases) that may be present in your particular environment. Blueair’s standard HEPASilent filter provides efficient filtration for environments where particles are the primary concern and gases are secondary. For any environment in which removing gaseous pollutants (including tobacco smoke) is a priority, we recommend the optional SmokeStop filter. All Blueair systems incorporate patented HEPASilent technology, the same system that earned Blueair 501 units the top two rankings in independent testing of Clean Air Delivery Rate (CADR), a measure of overall system performance. HEPASilent technology combines mechanical and electrostatic filtration methods to capture 99.97% of the tiniest 0.1 micron particles and gases. Blueair systems remove more of the smallest particles, compared to the HEPA systems of other manufacturers. They remove more dust than competitive units. Our standard filters are suitable not only for averag
