Filters & Water Treatment
Advanced Multi-Stage Filtration Technology
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.
Filter Replacement: Why Timing Matters
Maximum Performance, Minimum Effort
To ensure your Billi delivers the highest quality instant water and runs optimally, filter replacement is mandatory every 12 months. High-usage sites require changing every 6 months
Stop Biofilm, Keep Purity
Filters collect organic matter. Failure to change them leads to biofilm development, which directly causes reduced water purity and decreased unit performance.
Quick & Convenient Service
