This is a WRAS-approved replacement water filter cartridge designed to fit Lincat Filterflow FX series water boilers. Manufactured by Jantex using NSF-approved components, it is a direct equivalent to the original Lincat cartridge, produced to the same specification. The carbon block construction filters out chlorine and other impurities that affect water taste, while an integrated scale inhibitor helps reduce limescale accumulation inside the boiler.

In a busy kitchen or front-of-house environment, water quality and equipment reliability are closely connected. Limescale build-up is one of the most common causes of reduced boiler efficiency and premature element failure. Fitting a replacement cartridge on schedule is a straightforward maintenance step that protects the boiler and helps maintain consistent water quality throughout service.

A few practical points worth noting:

  • Compatible with Lincat EB3FX, EB4FX, EB6FX, EB6TFX, EB3FX/PB, and EB3FX/TT boilers
  • Cartridge fits directly into the boiler housing — no tools required
  • Typical service life of around 5,600 litres, roughly four to six months under normal use
  • High-volume sites may need to change the cartridge more frequently
  • WRAS approved and manufactured with NSF-approved components

It is worth tracking water usage or noting the installation date when fitting a new cartridge, particularly in high-footfall sites where throughput may be above average. Leaving a cartridge beyond its service life reduces filtration effectiveness and allows scale to form more readily.

This cartridge is well suited to any site running a compatible Lincat FX boiler — cafés, offices, hotels, staff canteens, and similar settings. If you are unsure whether this cartridge is the right fit for your boiler model, or if you are reviewing your water treatment approach more broadly, the team is happy to help.

Frequently asked questions

How often should this cartridge be replaced?

The typical service life is around 5,600 litres, which equates to roughly four to six months under normal use. High-volume sites — such as busy hotel lobbies or large staff canteens — may find they need to replace the cartridge more frequently, so it is worth logging the installation date and monitoring throughput where possible.

Which Lincat boiler models is this cartridge compatible with?

This cartridge is designed to fit the Lincat Filterflow FX series, specifically the EB3FX, EB4FX, EB6FX, EB6TFX, EB3FX/PB, and EB3FX/TT models. If you are unsure which boiler variant you have, check the model number on the unit before ordering.

Is this cartridge an official Lincat part?

No — this is a compatible replacement manufactured by Jantex, not an OEM Lincat part. It is produced to the same specification as the original using NSF-approved components, and carries WRAS approval. For most operators it performs equivalently to the original cartridge, but if your site has a maintenance contract that specifies OEM parts only, it is worth checking before fitting.
