Active Air Pre-Filters spl_bfg tree seedlingsExtend the effective life of your Active Air carbon filter with a corresponding Active Air pre filter. These pre filters block larger particulate matter such as dust and dirt from clogging the working surface of your filter. This keeps your carbon filter operating at top efficiency for much longer.
