The Billi filter 994052 is a premium cartridge offering the finest level of filtration in Billi’s range, purpose-built to keep your instant boiling or chilled system running sweet. It directly replaces the popular 994002 model yet slips into the same swing-change head, so you do not need new fittings. Crafted in partnership with European filtration leader BWT, it arrives ready for a tidy, tool-free install.
What’s new in the Billi 994052
While the day-to-day function mirrors the outgoing cartridge, the new build houses upgraded Fibron XC® media. This graded-density carbon fibre gives equal or better protection against fine sediment, chlorine and parasitic cysts, while a proprietary scale inhibitor shields the internal Billi heating element. Expect the same performance, all backed by BWT’s laboratory testing.
Filtration technology explained
Developed with BWT, the four-stage Fibron XC® core catches particles to 0.2 micron, adsorbs chlorine and organic odours and then treats hardness. The result meets NHMRC aesthetic guidelines for taste and odour, helping every cup taste just right.
Compliance note: This cartridge is certified to WaterMark Level 1 and tested to AS/NZS 3497 for potable water contact.
