Measure these two.

Measure the cartridge you're replacing, not its housing.

A Overall length — end to end, including caps or connectors

B Outer diameter — at the widest point of the body

Will it fit?

Match the cartridge format and the working parts.

Compare your current filters’ length, diameter, end openings and seals. A matching nominal size is a starting point; confirm the complete fit with HFS before ordering.

Nominal sizes vary a little between makers, so match the measurement rather than the label. What we can't tell you is how ours compares to a cartridge we didn't make and haven't tested, or whether a replacement affects your housing's own warranty; that one is between you and its manufacturer.

Match both the cartridge format and the exact UV lamp, sleeve, pin layout and system model. Send photos of the unit and current parts to HFS before ordering.

Plan around 6–12 months, depending on water quality and loading. A noticeable flow reduction can mean earlier servicing is needed.

Follow the UV manufacturer’s rated service interval. Visible light alone does not confirm that the lamp still delivers its required treatment output.

Year 1 supplies the specified cartridges and lamp. The Year 2 photos also show a sleeve and seals; confirm the exact accessories supplied with HFS. This listing is for the triple-filter version.

The replacement parts alone do not establish drinking-water safety. The complete UV system must be correctly specified, maintained and operated within its rated water-quality and flow conditions.

Yes. Send photos of your system label, current cartridges and fittings, plus their measurements. HFS can help match the correct replacement.
