I use the Camco CX90 filter as part of a filtering system consisting a 17 gallon plastic tub and a RV water pump to filter fresh water into my holding tank. This way I can take water directly from the river or filter the water in the park, some campgrounds water is brownish and stains.
When not boondocking this filter can be connected directly from the TT to a pressurized water system.
I just let the filter dry out between uses, if the ceramic is stained I scrub it. I can easily get a full season from a single cartridge.
