Advanced Filtration Technology
Billi provides world class drinking water filtration solutions in Australia, thanks to a 2019 partnership with BWT, Europe’s largest water treatment company. Our premium filters use BWT’s proprietary Fibron X® technology with a graded density profile for maximum capacity, consistent filter life, and superior water quality.
Even with high Australian water standards, local factors can impact tap water quality. Billi offers tailored solutions: our 0.2 Micron filter provides the highest filtration, removing chlorine, odour, and parasitic cysts (like Cryptosporidium and Giardia). Alternatively, our 5 Micron filter removes chlorine and limescale to significantly improve taste and odour.
Billi filters cater to all Home and Work environments.
INSIDE A BILLI FILTER
Advanced Multi-Stage Filtration
Every Billi filter is built in graded layers, each one doing a specific job as water passes through. Explore the construction, then see how Fibron X compares to a conventional carbon filter.
Outer carbon layer
Powdered activated carbon media takes the first pass, reducing taste, odour and chlorine.
Cyst reduction layer
Fine-porosity media with a graded density that captures cysts and finer particulate.
Post-filtration layer
Traps carbon fines and fine sediment before water leaves the cartridge.
Structural core
Holds the media in a graded profile and gives the cartridge its strength.
↓ WATER PASSES THROUGH EVERY STAGE IN SEQUENCE
Fibron X vs Conventional Carbon
BWT Fibron X carbon filter
Activated carbon fibre bonded in a graded density profile, with minimal binding agent. More usable surface area means higher contaminant reduction and greater capacity.
Conventional carbon filter
Loose granules held together with a resin binder. The binder blocks surface area and leaves channels, so water finds the path of least resistance and filtration quality drops.
↑ Surface area
Fibre exposes more active carbon than bonded granules.
↑ Capacity
More contaminant held before the cartridge needs changing.
↓ Channelling
Even structure stops water bypassing the media.

Why Timing Matters
To keep your Billi delivering the highest quality instant water and running at peak performance, filter replacement is mandatory every 12 months, or every 6 months for high-usage sites.
Filters collect organic matter over time, and if they’re not changed, this leads to biofilm development, which reduces water purity and unit performance.
Regular filter changes are quick and convenient, and they’re the key to keeping your system running at its best.
