Activated carbon filters
Illustrated Guide to Ventilation (BG 2/2009), compiled by Kevin Pennycook and published by BSRIA in 2009, states in relation to activated carbon filters: ‘Activated carbon is highly porous and can be used to absorb volatile chemicals. Practical applications can include the removal of volatile organic compounds and odours from an air stream. Activated carbon is usually combined with conventional filter techniques to provide filtration for larger particulates. Activated carbon filters are usually used in combination with secondary filters to prevent the pores becoming blocked with particulate matter.’
