Shower Filter Replacement Cartridge | Aqua Earth

Maintain peak performance with a shower filter replacement cartridge made specifically for Aqua Earth’s universal 20-stage shower filtration systems. Swap your old cartridge in minutes to keep filtration consistent and your showers feeling fresh.

This cartridge is built with the same 20-stage filtration system used across Aqua Earth shower filters, so you get the same materials and the same protection—just renewed.

Why choose an Aqua Earth shower filter replacement cartridge?

• Restores your filter’s 20-stage performance (so your shower stays consistent). 

• Long-lasting use — up to 12,000 gallons (often ~4–6 months depending on water quality and usage).

• Designed for Aqua Earth universal housings for a simple swap, no guesswork. 

20-stage filtration: materials inside the cartridge

Your cartridge uses a multi-layer blend that includes:

• Activated carbon

• KDF-55

• Calcium sulfite

• Vitamin C

• Ceramic balls

• Additional filtration layers (part of the full 20-stage stack)

These materials are used to help reduce common shower-water issues like chlorine/chloramine “smell,” rust/sediment, heavy metals, and limescale buildup—so your shower stays comfortable and your filter stays effective when maintained on schedule.

Installation: how to replace shower filter replacement cartridge (step-by-step)

1. Unscrew the filter housing (the main body) carefully. 

2. Remove the used cartridge. 

3. Insert the new cartridge in the same orientation. 

4. Reassemble the housing snugly (hand-tight is usually enough). 

5. Turn water on and flush briefly, then check for leaks. 

Tip (leaks): Most leaks come from a mis-seated or worn O-ring—re-seat it and tighten gently.
