Spectra Watermakers' High Capacity Pre-Filter Upgrade Kit, Two 10" Big Blue Filter Housings W/5 and 20 Micron Filters

This upgrade kit will prolong the time between pre-filter changes as it will have more holding or square footage of pleated filter space than the standard 2.5" x 9.75" seawater pre-filters. This Upgrade kit will work for Newport MKII Systems.
