Also, it seems to me that the density of the filtering medium in the two different filters would account for the difference in GPM.
Of course I considered that possibility. After all, you pay for what you get.
Here is my take on it. Had a pop up camper for years and never used a filter. Had a TT for years and never used a filter. The first time we used a filter was on our last TT. Bought it because I saw it hanging in the RV section at Wally World. It was one of those Camco in line ones that you attach to the water hose. No one has ever gotten sick from drinking tap water in any of our RVs. This was before drinking bottle water became an addiction.
Now, the incentive with having a full size refrigerator with ice and water dispenser is to use it and stop drinking bottled water. With that being said, the refrigerator also has a filter. So far, no one has used the water dispenser. However, we do use the ice maker and if you do get bad water it could be a problem. Then again I have two filters.
Like I said, we've camped a lot and no ones that I know off has gotten sick from tap water. As far as the fresh water tank, it gets sanitized once a year. For us, if it wasn't for the ice maker we probably would have removed the filter element after it was used up.
I could be wrong, but IMO, FR somehow got a deal with WaterPur in what I think is an attempt to capitalize on having everyone forced to buy the filters through them. Why is it that the filter assembly and filters have a specific FR part number. Are there no other filters out there that they cold have used?
