Choosing the right technology based on water quality

Pick a purifier based on water quality. RO suits high TDS (Total Dissolved Solids); UV/UF are best for soft water with low TDS. Combo tech covers most needs.

Pro-Tip: Use a TDS meter to check your water quality and choose the right purifier.
Understanding different types of water sources

Water sources vary in quality—municipal water has low TDS with chlorine, direct supply may carry rust and bacteria, while borewell water has high TDS, salts, and germs. Choose accordingly.

Pro-Tip: Mixed water sources? Go for a multi-stage purifier (RO + UV + UF) to handle varying TDS levels and ensure safe, clean water every time.
How to choose the right capacity based on family size

Pick tank size based on usage. Smaller tanks save space, while larger ones reduce refills—ideal when water access is limited or for homes with higher daily needs.
