The charcoal filter element (FT - FTC - CC) removes chlorine from the fresh water flush water
supply, as the RO membrane can only handle small amounts of chlorine without permanent
damage.
The charcoal filter used for the fresh water flush system will not plug up unless you have very
dirty domestic water in your boat
’ s supply tank.
The charcoal filter we supply removes 99.7% of the chlorine. Beware when buying other
charcoal filters. If they don
’ t specify the percentage of chlorine removed, don ’ t use them.
Cheap ones may remove only 60% or 70%. Also, there are aftermarket filters which are very
close to, but not exactly, the right dimensions, and they will not seal in the housing. If you
skimp on the charcoal filter you risk damaging a $600.00 membrane on the first flush. The
other factor is the flow rate that the filter can handle. Because the chlorine is adsorbed by the
charcoal, it must remain in contact with the charcoal for a sufficient period of time for the all
of the chlorine molecules to be captured. The filters we use can handle 1.5 gallons (6 liters)
per minute flow, and are good for 3000 gallons (12,000 liters) at 1.5 GPM, or six months,
whichever comes first. Regardless of the amount of water treated, the charcoal loses its
effectiveness after six months.
