Frequently asked questions

The 5T-RO is a 5-stage system available in pumped or non-pumped versions, while the 6T-BPUV adds a 6th stage with UV disinfection and a pump for higher performance. Check the specific listing for the exact stages included.

Pre-filters are typically changed every 6-12 months, while the RO membrane usually lasts 2-3 years depending on water quality and usage. Check your system's manual for its specific service schedule.

Non-pumped systems rely on mains pressure alone and don't need an electrical connection. Pumped systems use an electric booster pump for faster production and better rejection rates, especially useful on lower mains pressure.

Match your system's model (e.g. 5T-RO, EF300, EF500) to the corresponding filter set or membrane listing. Contact us with your system's model if you're not sure which set you need.

The EF300 produces 300 gpd (around 1000 litres/day) while the EF500 produces 500 gpd, giving higher output for larger households or higher demand. Both use their own matched membrane, so check which model you have before ordering a replacement.
