About the Billi 994052
The Billi filter 994052 (replaces 994002) is a premium Billi 0.2-micron replacement filter designed to deliver sub-micron filtration across Billi drinking water systems. It helps reduce sediment, chlorine, taste and odour while supporting reliable system performance.
It directly replaces the 994002 model and fits the same Swing Change filter head, so no additional fittings are required. Developed in partnership with Best Water Technologies (BWT), the filter is supplied ready for a tool-free installation.
What’s new in the Billi 994052
While the day-to-day operation mirrors the outgoing cartridge, the updated 994052 (replaces 994002) uses upgraded Fibron XC® media. This graded-density carbon fibre enhances the reduction of fine sediment and chlorine while helping limit scale formation that can affect Billi heating elements.
The filtration media was developed in partnership with BWT.
Water Filtration Technology
Developed with BWT (Best Water Technologies), the four-stage Fibron XC® core captures particles down to 0.2 micron, reduces chlorine and organic odours, and helps manage hardness through integrated scale treatment.
This filtration performance aligns with NHMRC aesthetic drinking water guidelines for taste and odour.
Compliance note: This cartridge is WaterMark Level 1 certified and tested to AS/NZS 3497 for potable water contact.

FAQs
Is the Billi 994052 the replacement for the 994002?
Yes. The Billi 994052 filter directly replaces the earlier 994002 cartridge. It uses the same Swing Change filter head, so the replacement installs into existing Billi systems without requiring new fittings.
Is this filter suitable for tank or bore water?
The Billi 994052 filter is designed primarily for treated mains water. Tank or bore water may contain higher levels of sediment, minerals or biological contaminants, so additional pre-filtration is usually recommended to protect the system and maintain filtration performance.
What is the difference between Fibron XC® and Fibron XT®?
Both filtration media are designed for Billi systems but serve slightly different purposes. Fibron XC® focuses on sub-micron particulate reduction and chlorine removal, while Fibron XT® typically includes additional scale control media to help protect boiling water systems.
How long does the 994052 filter last?
The 994052 filter provides up to 30,000 litres of chlorine reduction capacity, which typically equates to around 12 months of use for many homes and offices. Actual lifespan may vary depending on water quality and daily usage.
