Common questions
- Which water filter fits the Billi Home BCS?
- The Billi Home BCS takes the Billi 0.2 micron Fibron XC replacement filter 994052.
- How often should I replace the water filter in my Billi Home BCS?
- Every 12 months. Flow slows and performance drops off as the filter fills up, so it's worth doing on time.
- Where can I buy the 994052 in Australia?
- We track 7 Australian sellers for the 994052; the lowest listed price when we last checked was A$189.00 at Cass Brothers. Prices are re-checked daily and dated on this page.
- How do I fit the 994052 in a Billi Home BCS?
- No tools, a few minutes: 5 steps, listed on this page with the replacement video where the maker has one.
- What happens if I don't change it?
- The carbon stops reducing chlorine taste and odour and the flow from the tap slows as the cartridge clogs; a boiling-water tap with a scale-reducing filter builds scale in its tank faster.
- How do I reset the reminder?
- Billi's guides give no separate reset step: the filter monitor counts cups and days, and Billi's service line (1800 812 321) can reprogram the interval if needed.
