It depends on your water source. WASA supply usually needs RO, while tubewell water with iron needs an iron removal filter plus RO. We offer a free water test so you buy exactly what you need.
Sediment and carbon filters usually last 4–6 months, and the RO membrane 1–2 years, depending on water quality and usage. We send reminders so you never miss a change.
Cost depends on capacity, raw water quality and the level of automation. Share your location and target production, and we'll prepare a detailed quotation with a business plan.
