It's recommended that you replace your cartridge every 6 months or up to 10,000 Gallons for optimal filtration. However, depending on the quality of water and number of people in your household, we'd recommend replacing the cartridge every 3 months. A key sign of your filter getting old is if your water pressure begins to decrease, which is caused by sediment clogging the filter.
Sprite's SLC Shower Filter Cartridge Replacement is compatible with Sprite's Slim-Line and All-In-One filtered shower head models.
