All Blueair air purifiers come with the option of a Smokestop Filter
The Blueair 650E SmokeStop™ Unit is the ideal choice for allergy sufferers and other health-conscious individuals that need high-efficiency particle removal plus gas and odor control. The unit contains 3 Smokestop™ progressive carbon filters each with a honeycomb-type structure that improves airflow and has hundreds of odor and gas absorbing carbon pellets. Each filter contains coconut shell activated carbon impregnated with a 70/30 blend of Potassium Hydroxide (KOH) and Potassium Iodide (KI). The carbon eliminates volatile organic compounds (VOC), which are responsible for odors.
Made of coconut shell charcoal*, these activated carbon granules will remove gaseous pollutants which are not particles but molecular substances dissolved into the air. These include cigarette and cigar smoke or other VOCs (volatile organic compounds), including household paints and other chemicals. Granules, rather than compressed sheet carbon, offer much greater surface area and therefore more effective adsorbption levels of dissolved pollutants.
*NOTE: The activated carbon typically used by Blueair before impregnation) is a coconut shell material with an activity level of 60% or more when tested with carbon tetrachloride.
200Series - .81kg activated carbon per Smokestop filter
400Series - 1kg activated carbon per Smokestop filter
600Series - 1.83kg activated carbon per Smokestop filter
You may notice a slight odor from the enhanced active carbon when the filter is first used; this will quickly dissipate.
