Benefits
- Customisation: Unlike fixed cartridges, this refill case gives you the freedom to select your media based on your own water quality needs.
- Cost-effective: Refill only the media rather than replacing the whole cartridge.
- High capacity: The “Fat” size accommodates more media volume, extending service life and reducing frequency of replacements.
- Durability: With a strong polypropylene body, it withstands the conditions present in many water filtration setups.
- Flexibility: Suitable for both domestic and light commercial water treatment applications.
Use Cases
- Ideal for households with high sediment or varied contaminants wishing to customise media (e.g., carbon + KDF).
- Perfect for water refill shops, bottling plants, or commercial sites where filter media needs differ or change over time.
- Fits into existing 20″ filter housing infrastructure, making it an easy upgrade for systems requiring larger diameter cartridges.
Installation & Maintenance Tips
- Ensure your housing is rated for the 4.5″ diameter cartridge and that O-rings/gaskets are correctly seated.
- Choose your media based on water test results: e.g., activated carbon for taste/odour removal, KDF for heavy metals, resin for hardness or specific ions.
- After filling the media and installing the cartridge, flush your system according to the manufacturer’s instructions to remove any residual fines.
- Monitor pressure drop weekly; if your system shows increased restriction, it may be time to replace or refill the media.
- House the cartridge in a clean environment. Replace or rinse pre- and post-filters as required to maintain optimal performance.

FAQ
Q: Will this cartridge fit my current filter housing?
A: If your housing accepts a 20″ “Fat” format (approx. 4.5″ diameter internal), yes — measure your internal diameter and length to confirm compatibility.
Q: What media should I fill it with?
A: That depends on your water quality goals. Activated carbon is ideal for removing chlorine/taste/odour; KDF is excellent for heavy metals or bacteria reduction; resin or siliphos can target scale, hardness or specific ions.
Q: How often should the media be replaced?
A: It depends on your water usage volume, contamination level, and flow rate. Monitor system performance (flow reduction, pressure drop, taste/odour changes) as indicators.
Q: Is this cartridge suitable for commercial use?
A: Yes — it is designed for both residential and commercial filter housings.
Q: What are the delivery options?
A: We offer next-day delivery (see our delivery policy) for orders placed before the cut-off time.
Q: What if I need technical support?
A: Contact our team at +27 10 020 1600 or via email terence@puritech.co.za and we’ll help you with installation advice, media choices, and compatibility.
