Product Description

Blueair 400 Series Smokestop Filter with 1 kgs granules carbon + carbon sheet

The Blueair 400 series Smokestop filter is the ideal choice for allergy sufferers and other health-conscious individuals that need high-efficiency particle removal together with gas and odour reduction. Refer Particle Filter for particle removal efficiency data. The carbon section of this filter is a two layer structure consisting of an overall carbon sheet plus 1 kgs of odour 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). This special 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 a far greater surface area and therefore more effective adsorption levels of dissolved pollutants.

For maximum clean air, choose Blueair Premium Smokestop filters - specially designed to remove both odours, road fumes, smoke, off-gassing, chemical residues, VOCs etc. as well as pollens, bacteria, pet dander, mould spores and other airborne particles.

DISPOSAL: Used filters can be placed in regular rubbish disposal and will decompose, converting into harmless carbon dioxide and water.
EASY REPLACEMENT: 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.

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.
