Brand: ZeroB
Ion Exchange engineering for genuinely difficult water
Our editorial score
Very good — recommended
Homes with iron staining, extreme hardness or nitrate problems — Bengal, Assam, Bihar and the hard-water belt.
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.
Practically, that means the pre-treatment can be configured to your actual water rather than to a generic assumption. Get a lab test first, then talk to ZeroB about the right configuration. You will pay less than you would replacing a mis-specified membrane twice a year.

Specifications are from manufacturer literature and were checked at the last price-verification date. Brands occasionally revise stage counts, tank sizes and warranty terms without changing the model name — confirm against the current listing before purchasing.
The domestic brand of Ion Exchange, one of India's largest industrial water-treatment companies. That lineage shows: ZeroB is unusually strong on genuinely difficult water — iron removal, hardness, nitrate — and it is the brand to look at when a standard RO is not the right answer.
