Shower Filter Replacement Cartridge for Weddell Duo Shower System
This shower filter replacement cartridge is an activated carbon fiber cartridge designed for compatibility with Weddell Duo shower filter housings. It features a compact cylindrical design measuring Ø43 × 90 mm (Ø1.69″ × 3.54″) and is supplied as part of a two-cartridge replacement set.
The ACF media is designed for chlorine reduction and high-flow shower filtration. With a rated service life of up to 8,000 gallons, a flow rate of 2.8 GPM, and a chlorine removal rate of ≥70%, this cartridge is suitable for shower filter replacement and OEM applications.
ACF Shower Filter Replacement Cartridge
Activated carbon fiber provides a high-surface-area filtration medium in a compact cartridge structure. This allows the cartridge to provide chlorine reduction while maintaining a relatively high flow rate for shower applications.
The cartridge has been designed for the dimensional requirements of the compatible shower filter housing and can be supplied as a replacement component for the existing system.
Two-Cartridge Replacement Set

This shower filter replacement system uses two different filter cartridges working together.
The cartridge described on this page uses Activated Carbon Fiber (ACF) as the primary filter media. The second cartridge uses a PP + Activated Carbon Fiber composite structure.
For information about the second cartridge, see our PP + Activated Carbon Fiber Shower Filter Cartridge .
Using two different cartridge structures allows the filtration system to combine different filtration media within the same shower filter housing.
PP + Activated Carbon Fiber Cartridge
The second cartridge combines PP filter media with Activated Carbon Fiber in a compact cartridge structure. It is designed to work as part of the same two-cartridge shower filter replacement configuration.
If you are sourcing the complete replacement set or need a customized version of either cartridge, our team can manufacture the cartridges according to your required dimensions, structure, and filtration specifications.
