Ozone may be removed from air by molecular filters. To help customers assess the effectiveness of different products, Camfil Farr introduce an ozone removal efficiency rating system. This is a first in the filtration industry.
All the filters use a high quality broad spectrum adsorbent, based on activated carbon to destroy the ozone molecules. Laboratory tests show that filters based on the use of potassium permanganate, which is itself a strong oxidising agent are unlikely to be as effective.
