Review on 🚰 iSpring FWDS150K Replacement Filter Cartridges by Dwight Tim

After building a new house out of town we checked our new well and the water was fine just a little manganese. We didn't do anything about it for a few months, but then we noticed white plaque and stains on the glass doors of showers, dishes, and faucets. A lot is also designed inside the dishwasher. I didn't want to make a regular salt-based water softener, so I found that many municipal water systems have been adding polyphosphate for years without a problem. The iSpring anti-calc cartridge is actually not a filter but a polyphosphate injector. Inside are many small spheres that disintegrate when water flows through them. Everything cleaned up from the moment of installation. I wish I had done this earlier. Highly recommend if you have a scale.
