How to Install

EASY, TOOL-FREE MAINTENANCE
Step 1: Water Off. Turn off the main water supply to your shower to prevent water flow.
Step 2: Unscrew Housing. Unscrew the filter housing (the chrome casing) into its two halves by twisting the bottom half counterclockwise.
Step 3: Remove & Insert. Remove the used filter cartridge and dispose of it. Insert the new 20-Stage Replacement Cartridge into the larger, top half of the filter housing chamber. Ensure the O-ring at the top of the cartridge is properly seated.
Step 4: Seal Housing. Carefully screw the two halves of the filter housing back together and tighten securely by hand. Do not use tools.
✅ Done! Turn the water supply back on. Run the shower for about one minute to flush any carbon dust from the new filter before your first use. The cartridge is typically effective for 4–6 months.

How often should I replace the 20-stage filter cartridge for best performance?
For optimal performance and to maintain the highest quality of filtered water, the 20-stage filter cartridge should be replaced approximately every 4 to 6 months. This lifespan ensures that the extensive filtration media remains potent and fully effective at consistently removing contaminants and maximizing the health benefits for your skin and hair.
What contaminants does this advanced 20-stage replacement cartridge target?
The cartridge contains 20 layers of specialized filtration media, including KDF-55, Calcium Sulfite, Activated Carbon, Vitamin C, Mineralized Balls, and Zeolite. This complex system is designed to significantly reduce or eliminate chlorine, chloramine, heavy metals, sediment, limescale, bacteria, and fluoride, providing ultra-clean, balanced water.
How will I know when the 20-stage filter needs to be replaced?
Key indicators that the cartridge is saturated and losing effectiveness include the reappearance of chlorine smell in the water, a return of dry or itchy skin and brittle hair, or a subtle but noticeable decrease in water pressure due to debris accumulation within the media. Replacing it prevents these issues and maintains results.
Is this replacement cartridge compatible with all StoneStream filters?
This cartridge is specifically engineered to be the direct, seamless replacement for the StoneStream 20-Stage Shower Filter systems (such as the Advanced Hard Water Shower Filter and the Fixed Wall Showerhead Filter). It is designed to fit precisely into these housing units for full functionality.
Is the replacement process for the cartridge complicated or difficult?
No, replacing the cartridge is a straightforward, tool-free process. You simply unscrew the filter housing (the main casing), take out the old cartridge, insert the new one into its slot, and securely screw the housing back together. The quick swap ensures minimal downtime and instant return to purified showering.
