Sediment filters remove suspended particulates from the raw water entering the watermaker, helping to prevent damage to the pumps and clogging of the membranes.
This 20-0019 5 micron sediment filter cartridge is used as the standard pre-filter on FCI Aqualite watermakers.
The 20-0019 is also used as the secondary (finer) pre-filter on all Aquamiser+ watermakers, which use two pre-filters in series (a coarse and a fine).
