- 9-litre tank is genuinely enough for a family of five during a supply cut

The deciding factors
If someone asks for one water purifier recommendation without telling me anything about their water, this is the answer. The Grand Plus is not the prettiest or the cheapest unit in this list, but it is the most consistently correct one: an RO membrane rated to 2,000 ppm input, UV and UF stages behind it, and a TDS controller so that low-TDS supply does not get stripped to tasteless.
Against that, ZeroB Suraksha Plus makes its case differently: If your water leaves orange stains in the sink, scales up a geyser in six months, or has a nitrate problem, you do not have a normal RO purchase — you have a water-chemistry problem, and most consumer brands will sell you a standard unit that dies early. ZeroB is the exception, because it is the domestic arm of Ion Exchange, which builds industrial treatment plants for a living.
Our practical advice: unless the KENT Grand Plus's specific advantages match a real constraint you have — tank size for long water cuts, a higher TDS rating for brackish supply, hot water you will genuinely use — the cheaper unit is the better purchase. In this category, paying for capability you will never use is the most common way money gets wasted.
