A Look Inside a Typical RV Water Filter
Ray's Product Reviews
-
In this video, I cut open a Membrane Solutions RV water filter to see what is inside. It resembles the filters people typically use in RV parks and campgrounds.
I found it had a pair of soft foam pieces holding a selection of charcoal and, at one end, a more dense foam layer. It is suitable for blocking sediment and making the water taste better but not for removing tiny things like bacteria or viruses that may make a person sick. For that, you need a more expensive multi-stage filter system. It says on the label that you shouldn't use it for microbiologically unsafe water or of unknown quality.
