Review on 💧 iSpring WDS150K Whole House Water Filter by Michael Reynolds

I have added this single iSpring Anti-Calc filter in addition to the previously installed iSpring triple filtration system. The previous purchase was a triple filtration system for sediment, carbon and iron/manganese. This one now adds a polyphosphate liner that really removes scale and makes the water a lot softer. In fact, this is not a filter, but a cartridge (heavy) with polyphosphate granules that dissolve in water. This is typical of urban water systems everywhere and has been so for a long time. Easy to install like the others and works very well. Replacement anti-calc cartridges are expensive but should last up to a year. It's probably a lot cheaper than limescale, which will damage all of your water heaters, water heaters, and faucets. If water retention is an issue I would highly recommend this product.
