        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.

                I purchased same item last year, wrote a review, and said I'd be back. Time to get RV out of storage and install new filter, so I purchased again on-line. Good company to deal with. Thanks
