Refill Case 10 Inch Standard 2.5″ Diameter – Customisable Filter Cartridge Shell

The Refill Case 10 Inch Standard 2.5″ Diameter offers a high‑quality, refillable cartridge shell designed to fit standard 10″ filter housings with a 2.5″ diameter. You can customise the internal media—such as activated carbon, resin, Siliphos or KDF—to match your specific water‑filtration needs. Because the shell is empty and refillable, it provides flexibility and allows you to create tailored solutions rather than relying on pre‑loaded cartridges.

Key Features of the Refill Case 10 Inch Standard 2.5″ Diameter

• Size: 10-inch length, standard 2.5″ diameter, suitable for most residential systems.
• Material: Polypropylene shell – strong, durable, and resistant to chemical degradation.
• Refillable Design: Empty cartridge allowing you to load preferred filter media.
• Built‑in Pre & Post Screens: Prevents media loss during operation and improves reliability.
• Cost‑Effective & Eco‑Friendly: Reusable shell helps reduce waste and lets you replace media only.

Applications & Benefits

This cartridge shell is ideal for point‑of‑use or whole‑house systems where custom media blends are needed—for example, systems tackling heavy chlorine, iron, sediment or requiring post‑treatment mineralising. The Refill Case 10 Inch Standard 2.5″ Diameter supports higher media volume than smaller cartridges and offers better service life. Because you fill it yourself, it gives you full control over performance and cost.

Installation & Maintenance Tips

• Check that your filter housing accepts a 10″/2.5″ cartridge.
• Load your chosen media according to manufacturer guidance (e.g., carbon first, then KDF or resin).
• Install the cartridge in the correct flow direction and ensure the O‑ring seals are intact.
• Monitor pressure drop; once it rises significantly or flow slows, refresh the media.
• Flush the system after loading new media to remove loose particles before drinking.
