Differential static pressure across filters will cause differential contaminent accumulation in the media. Profilter reversible carbon filter is the only filter to offer a solution with the twist lock flange and end cap allowing to reverse the filter and equalize contaminent distribution in the media.
Manufactured with only the finest high porosity activated carbon, the PROfilters 45s and 70s effectively remove 99.5% of volatile organic compounds. The factory installed high capacity PREfilter eliminates bigger particles such as dust to prevent premature usage of the carbon. Rated for a continuous worry-free operation, light weight and its compact dimensions, make the PROfilters 45s and 70s ideal for residential filtration.
