We have so much scale in our water that an inline scale filter installed on our evaporative cooler stopped working after a month. I sawed it open and it was a solid block of salt. I was resigned to replacing the filter every month, or building a manifold with half a dozen filters and then I found this! It works perfectly. The advertising is a little deceptive. It says you can wash it out, which implies you can keep using it forever, but evidently, the beads inside will eventually stop working. But so far, it's been on our swamp cooler for 6 months. The cooler runs 24/7 and the water is scale free!
