Kent Ultra Storage review: a cheap UV+UF purifier that only makes sense for low-TDS tap water

How we researched this

We have not used this purifier. This review is built from Kent’s product page, the Flipkart listing and its owner reviews, all read on 12 November 2026. We could confirm the price, the purification type and Kent’s own suitability limit. We could not verify flow rate, UV effectiveness or durability, and the two sources disagree on several basic specs (listed below).

Check your TDS first

This is the one question that decides whether the Ultra Storage is a sensible buy. Kent’s page says it is “suitable for low TDS water/municipal water supply up to 150”. It has no reverse osmosis stage, so it does nothing to dissolved salts, hardness or dissolved contaminants. If your tap water is soft municipal supply, a UV+UF unit is a reasonable, cheaper choice. If it comes from a borewell or tanker, or you don’t know its TDS, this is the wrong product.

Purification: what UV+UF does and doesn’t do

Kent describes the purification as an activated carbon pre-filter for taste and odour, a UF membrane and a UV lamp, with an 8-litre storage tank and a UV-fail alarm. UV and UF together target bacteria, viruses and cysts. Kent rates the flow at up to 60 L/hr, which is much faster than an RO purifier, and because there is no RO membrane there is no reject water.

Spec sheet problems

Kent and Flipkart do not agree on the basics. Kent lists 4.72 kg, 375 x 280 x 410 mm and a UV-fail alarm. Flipkart lists 13 kg and 32 x 50 x 38 cm, and its table says “Alarms: No”. Flipkart’s title says 8 L, but its description says 7 L. Flipkart’s “key features” block also describes reverse osmosis and mineral addition, which this model does not have. We would trust Kent’s figures over the retailer copy, but treat both with care.

What owners report

The Flipkart listing shows 4.0 stars from 7,802 ratings. Of those, 1,102 are one star (about 14%) and 4,279 are five star. The review pool also includes an “UV + UF + Alkaline + Copper” variant, so the average does not describe this model alone. Many recent negative reviews read like buyers who needed an RO: “This is not RO”, “There is no TDS removal”, and one complaint that the listing does not say it won’t work for high-TDS water. Kent’s own page shows five short positive quotes, one of which says it is “good for low tds water”.

Running costs and warranty

Flipkart states a 1-year domestic manufacturer warranty with on-site service. Kent’s product page for this model does not list a warranty period or filter prices, so we cannot estimate yearly running costs. When we checked, the purifier was out of stock on Kent’s store at ₹8,699 (MRP ₹13,999) and in stock on Flipkart at ₹7,799.

Should you buy it?

Only if you have measured your water and it is genuinely low in TDS. In that case it is a cheap, fast purifier from a mainstream brand. For borewell, tanker or untested water, spend more on an RO model. Our score is provisional and will change once we can test a unit.
