How much carbon (by weight) is in each filter?

Often, the weight of carbon in a filter is used to determine how effective an air purifier is in removing smoke-related pollutants, but the amount of carbon in the filter is not the most important factor. The AHAM verifide Clean Air Delivery Rate (CADR) value for smoke is best for determining the removal of harmful fine particles from smoke. Thanks to the proprietary Blueair HEPASilentâ„¢ technology, all Blueair filters are optimized for maximum performance and protection from air pollution.
