Comments about 3M RV/Marine Filter Cartridge A1 for US-A1 Filtration System:

I have small hands and (obviously) not a great deal of hand torque, because I could NOT get this installed for the life of me...whereas my friend who is much stronger, with a much larger hand, and apparently torque, installed it in 2 seconds. It was weird.

            I needed to replace the water filter underneath the sink in my Winnebago View Motor Home. It had been two years since I bought the RV and I knew that the filter was at the end of it's useful life. I was surprised at how expensive these replacement cartridges are. I looked around and found that Jamestown had the best price and they shipped it for free to boot.

              Comments about 3M RV/Marine Filter Cartridge A1 for US-A1 Filtration System:

              Since the water in my RV is generally good, I'm not sure how much I actually need this filter or what, if anything, it does for me. This is not to imply that there is anything wrong with the filter. I suspect that once per year replacement is excessive for me. Since it is expensive, in the future I may just carry a spare and replace it if I detect any issues with my water.

              Comments about 3M RV/Marine Filter Cartridge A1 for US-A1 Filtration System:

              I recently bought a used RV. It was still winterized when I took delivery from the private owner. I didn't even realize that the unit had an in-line filter until I dug into the kitchen cabinet and found an cartridge taped to a shelf.

              I went to the nearby RV outlet to look for a replacement because all the literature said that I really need a filter. I bought a different brand than the 3M because it claimed to have a "universal connector." Apparently the 3M is not from this umiverse because the unit didn't connect in the same way.

              So, if you have a 3M, make sure you get a 3M replacement. It does cost about twice as much as other filters. But the cylinder is also a bigger diameter. I'm hoping it means it will last twice as long.

              One more thing. I tasted the water coming from the RV faucet both before and after I installed the filter. While the taste wasn't bad without the filter, the taste was amazingly good with the filter in place. It is as good or better than the best bottled water I have ever tasted. The taste alone makes this a great choice.
