Review: Works well with the iSpring system - This is what I've been using since 2022 on our iSpring RO and has worked as advertised. We're on well water, where the TDS can creep up above 1000, perhaps due to the salt use on our water softener. Using these filters, the TDS comes out at around 42, making the water safe for drinking. We use a distiller as well, which create about a 3-TDS water; we mixed the two to create about a 20 TDS great tasting water, good for drinking, cooking and coffee. I do replace the RO restrictor every time I replace the membrane to make sure it works efficiently. I also use a flush kit for the membrane to help it stay as clean as possible. This kit is a good value and I recommend it. ## Features - Reverse Osmosis Replacement Water Filters: Experience what water should taste like with the Express Water reverse osmosis water filtration system reducing up to 99.99% impurities. - Water Purification System: Drink the healthiest water on Earth.
