Installing or replacing Sprite shower filters typically requires no tools or plumbing experience. Often, it's as simple as unscrewing the filter housing from the hose, removing the old cartridge, inserting the new filter, and hand-tightening the housing back onto the hose connection. If installation is between the shower arm and showerhead, unscrew the current head, attach the filter body, and reattach the showerhead. Run water for 30 seconds after installation to flush the new filter and activate the media. Mark your calendar or set reminders for timely future replacement based on your model's recommended lifespan.
