Photocatalytic filters
Illustrated Guide to Ventilation (BG 2/2009), compiled by Kevin Pennycook and published by BSRIA in 2009, states: ‘Photocatalytic filters can be used to remove odours and micro-organisms. This technology is based on titanium oxide. An ultra-violet light source is used to initiate a photocatalytic process resulting in the formation of hydrogen peroxide and hydroxyl. These two substances possess powerful oxidising properties. Through mutual interaction they are able to decompose odorous substances into carbon dioxide and water. The filter can also remove bacteria and deactivate viruses.’
