The Charcoal filter is there solely to remove chlorine from your fresh water flush water. This is commonly referred to as a Carbon filter. The product water made from your watermaker does not contain chlorine, however almost all city or dock water does have chlorine in it. Once wet, the charcoal filter should be replaced every 6 months. Unfortunately, there is no way to test the quality of your charcoal filter.

 

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%. There are also 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 absorbed 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.
