Key Features

• 【Common Fitment】 this filter replacement is common size, so it can fit any similar design shower filter shell (e.g.: fit for 10, 12, 15, 17, 18, multi-stage or 20 stage filter shell).
• 【More Value- 4 Pcs 20 Stage Filter Replacement Cartridges】 4 pcs 20 stage shower filter cartridges included.
• 【Long Lasting, Economical Filtration】The filter cartridge replacing frequency depends on your local water quality and use frequency. The worse your local water quality is (e.g.: your local water is too hard), or the more often or more people use it, the more often you need to change it. Usually, if shower flow suddenly drops, or water smells chlorine or feels hard again, etc., then it’s time to replace cartridge.
