Review on Culligan HF360A - Optimized Standard House Filtration System by Tamara Jackson

Eventually I had to replace my original Culligan block with this one. Well, nothing lasts forever, but 15 years of service, filter changes and hard water building up in my well, that was a while, mostly because the clear plastic became so stained that the filter was hard to see, mind you, 15 years of full service . We live in a country house and I use this as a pre-filter from my well to my house. Note: Install in series after the surge tank (you can have more flexibility if you install a booster pump), not before or just between the surge tank and the wellhead. You can buy volumetric filters online for this size and any combination you want, I use these for sediment and then have a triple version under my sink for activated carbon filtration and a micro filter which I was surprised we found in this test comparing bottles outperformed water samples I sent in.
