I really loved these. They worked great in the short term, but unlike canco rv water inlet filter, these only lasted about 3 months unlike the canco ones that worked twice that long, 6 months. So you may think you are saving money in the long run. In harsh water conditions you will buy 4 of these a year, compared to canco, which you may have to replace only 2 to 3 times a year. Stick with the good, proven brands, Canco isn't just a brand name, your paying for their quality no the name. I promise you this is true
