Hi,
Does anybody know if an activated charcoal filter removes chlorine
from fresh water such as that taken on board from municipal supplies

I read the following within an article in "Ocean Navigator" - online

"A charcoal filter is also required to prevent chlorine in water from
dockside sources getting to the membrane. It should be placed in the
system before the watermaker when tank water is used during
backflushing."

Further, I have had an activated charcoal filter for drinkable water
using the cartridge disposable household plumbing in-line filter for
years but have no idea as to how often one should change them.

Anybody know?

regards
Peter
