I ordered these Carbon Filter Replacement Cartridges for my RO Unit and have been very pleased. They will fit all standard RO unit canisters. We use our RO water for drinking water, water for our more delicate plants, and for our aquarium (which really helps to minimize algae growth). Regarding their effectiveness, our tap water tends to have a noticeable taste and these cartridges totally eliminate this undesirable taste in our water. Based on how much water you use, we typically replace these every 3 to 6 months. The multi-pack is a great deal and we will continue purchasing this brand. Hope this feedback helps with your purchase decision. Read more
