Review on 🚰 iSpring High Capacity Replacement Filter for Iron Manganese Reducing Whole House Water Filtration System, 4.5"x20 by Lisa Collins

This is the second filter I have bought. I installed the first and ran water through it, but only to check for leaks. It stood for a year and when I was finally able to install the new pool I filled about 12 inches of water and decided to test if I had iron in the water by throwing a shock in the water. After a few minutes it turned brown. I felt that when I ran water through the filter a year ago the filter was activated and its effectiveness has probably greatly diminished by now, so I bought a new filter cartridge and filled the whole pool. The result is the same. Don't waste your money on this filter as it is not cheap and did little to solve my high iron well water. And on a side note, my water was tested for 1.65 ppm iron. The filter is designed for 3 ppm iron. Very disappointed
