The Blueair Composite (SmokeStop™) filter is the ideal choice for allergy sufferers and other health-conscious individuals that need high-efficiency particle removal together with gas and odor control. Refer Particle Filter for particle removal efficiency data. The carbon section of this filter is a honeycomb-type structure that improves airflow and has thousands of odor and gas absorbing carbon pellets. Every "Smokestop" 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 many and various odours.
Made of coconut shell charcoal*, these activated carbon granules will remove gaseous pollutants which are actually not particles but rather 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 adsorption levels of dissolved pollutants.
Choose Blueair SmokeStop Filters, which are specially designed to remove odours, road fumes, smoke, offgassing, chemical residues, VOCs etc. or Blueair Particle Filters to remove dust, pollen, bacteria, pet dander, mould spores and other airborne particles.
Used filters can be placed in regular rubbish disposal and will decompose, converting into harmless carbon dioxide and water.
Regularly replacing the Blueair filters according to manufacturer recommendations is critical to ensuring that Blueair air purifying systems keep performing as they should.
Easy to replace: when the filter needs to be replaced (typically every 6 months if operating 24/7, 12 months operating 12/7), simply open the unit, lift out the old filters and slide in the new ones. No screws, hooks or tools and less than one minute is required. Blueair filters require no weekly additives or filter washing.

*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.
