Catalogue listing — not a hands-on review
We have not tested this unit. The specifications below are parsed from the manufacturer's own listing, the features are their wording, and the score is calculated from those specifications rather than assigned by an editor. For models we have examined in depth, see our ranked water purifiers guides.
About this model
ZeroB's ZeroB Kitchenmate UV Under-Sink uses UV purification and sells for ₹10,114 on Amazon.in (MRP ₹12,490, so 19% off on the day we checked).
There is no RO stage, so it suits soft municipal water under about 200 ppm TDS. It will kill or filter microbes but will not lower salts, so it is the wrong choice for borewell water.
This is a catalogue entry, not a hands-on review. Every number above is taken from ZeroB's Amazon.in listing (ASIN B0BLKBCYG9) as it stood on 12 October 2026, and the score is worked out from those numbers alone.
Manufacturer's stated features
- No RO, so no reject water — the right choice for low-TDS municipal supply
- Fits under the sink and keeps the counter clear
Worth noting
- Without RO it cannot reduce dissolved salts — test your TDS before buying
- Tank size is not listed
When this is not a good choice
Every condition below is derived from this product's published specifications and from how it compares with the water purifiers we track — so you can check each one against your own room, supply or budget rather than take our word for it.
Your supply runs above 200 ppm TDS
It is suited to supply up to about 200 ppm. Above that this technology removes nothing dissolved, so the water will be disinfected but not desalinated.
Purifiers for high-TDS supply →Your area has documented arsenic, fluoride or nitrate contamination
There is no reverse-osmosis stage. UV and UF deal with bacteria, viruses and cysts, and remove nothing dissolved — so against those contaminants this offers no protection at all, whatever the TDS reading says.
Book a NABL lab water test →You live outside a metro or a major service town
ZeroB's service network is rated good rather than excellent. Filter availability and callout times are what decide whether a purifier is still running in five years, and they are worth checking for your pin code before you buy.

About ZeroB
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.
