10 Best Water Purifiers for Home in India – Reviews & Buying Guide

Are you searching for the best water purifier for your home?

Well, you’ve come to the right place.

Do you or your family members frequently suffer from waterborne diseases?

Does your drinking water smell like rotten food, looks polluted or tastes salty?

Don’t worry! You are not alone!

All you need is a good water purifier.

RO water purifiers are a great choice for almost all Indian homes. RO (Reverse Osmosis) purifiers are so popular in India that the term ‘RO’ has become synonymous with ‘water purifiers’.

RO water purifiers, in combination with technologies like UV, UF, and MF, remove almost all commonly found impurities like: mud, sand, dust, bacteria, virus, cysts, and excess dissolved solids like calcium, magnesium, potassium, sodium, chlorides, and heavy metals like lead, arsenic, fluoride etc.

Buying a new water purifier for your home has to be a well thought out decision as your entire family’s health depends on drinking pure water.

The best part is you can easily buy an RO water purifier online or from your nearest home & kitchen appliances store. But the unfortunate part is buying the right one is not easy. With hundreds of models of water purifiers from several brands, it becomes quite challenging to find the best water purifier for your home.

  • TDS Controller keeps the essential minerals in the purified water.

Why is it Good?
Kent Grand Plus offers 7 stage purification using RO, UF, and UV and can be used for all types of water sources like bore-wells, tanks or tap water. Kent Grand Plus is also suitable for high TDS water and can purify water with TDS as high as 2000 ppm.

The purifier features a transparent cover giving you a complete view of all that works behind to give you 100% pure and safe water. The storage tank with a capacity to store 8 litres of purified water and purification capacity of up to 20 litres per hour makes this a good fit for a large family.

Built-in SMPS keeps the purifier completely safe from voltage fluctuations, a common feature in most Indian households.

Why Buy Kent Grand Plus?
Unlike most RO purifiers which remove all essential minerals from the purified water, Kent Grand Plus uses TDS controller which maintains a safe level of essential minerals in the purified water.

Filter change alerts & UV fail alarm keep you updated on when the filters need replacement or if there is any fault in the UV. These features also make Kent Grand Plus a fail-safe water purifier, because the purifier will stop all operations if the filters are not replaced within the next sixty hours of the alert.

Most RO water filters recover only 20% of water as purified water and reject about 80%. But Kent Grand Plus employs Save Water Technology that recovers more than 50% water as purified water. This is not all, this truly best water purifier machine also stores the rejected water in a separate tank enabling you to easily reuse this RO waste water for other purposes. Kent Grand Plus reduces wastage of water and saves hundreds of litres of water daily.

Havells Max, from Havells Water Purifiers, is one of the latest UV + RO water purifiers. Manufactured by Havells, the leading brand of electronics items in India, Havells Pro has got everything that makes it one of the top 10 RO water purifiers in India.

In most other RO water purifiers with features like TDS controller, some of the water bypasses the RO membrane and is only purified using UF membrane, this bypassed water is later mixed with RO water to maintain the essential minerals in the purified water. This means 100% of the water does not pass through the RO membrane.

In Havells Max 100% of the water passes through RO and UV to make every drop as pure as possible. Mineralz Cartridge adds all the essential minerals without compromising the purity and health and Revitalizer cartridge improves the hydration and mineral absorption to make water healthier.

Why Buy Havells Max?
Havells Max is an amazing RO+UV water purifier in its price range. The 7 Stage purification, with Sediment Filter, Activated Carbon Filter, RO Membrane, Germicidal UV, Mineralz Cartridge, Silver Impregnated Taste Enhancer and Revitalizer Cartridge, gives you 100% pure and great tasting water that is full of essential minerals.

Storage Capacity of approx. 8 litres and purification capacity of up to 15 litres is more than sufficient. Havells Max can be placed on a table/counter top or mounted on a flat wall and in the corner. Reverse Osmosis purifiers from no other brand give you an option for corner installation.

Advanced Automatic Alerts for self-diagnostic, purification process, tank full, low water pressure, and error alerts for UV, SV, and pump failure. Another first of its kind, Havells Max features unique soft touch faucet that ensures zero splashes, zero contamination, and smooth flow.

Havells Max also features contamination proof tank cover which keeps the purified water in the storage tank free from all kinds of foreign impurities like dust and insects. The best part is the storage tank is removable, which means you can very easily remove the storage tank for the periodical cleaning.

Advanced voltage fluctuation guard ensures that the purifier performs well in the voltage range of 170 V – 330 V. Power trips if the voltage exceeds 330 V or if it drops below 170 V, protecting the purifier from any electrical damage.

Starting from the purification technology first, AO Smith Z8 comes with 8 stage purificationthat is capable of removing all common impurities from the drinking water. Quality water purification means you can be 100% sure of every drop of water that you get from the Z8. Mineraliser Technology (MIN-TECH) adds back the essential minerals in the purified water to ensure that the water tastes fresh and natural. The mineraliser also balances the pH level of water to maintain the alkalinity and makes it healthy.

Most RO water purifiers waste a lot of water and this has been a cause of concern for every right-thinking citizen. Unlike most RO water purifiers, the AO Smith Z8 with its Advanced Recovery Technology saves twice as much water as any ordinary RO purifier would save.

AO Smith Z8 also features separate smart alert indicators for RO membrane and filters. These indicators are provided near the temperature display and start glowing when it is the time to change the RO membrane or the pre and post RO filters.

The glow effect will guide you to the water purifier without turning on the kitchen lights.

Another feature that is rarely available in any other brand is dispensing of purified hot water. AO Smith Z8 lets you dispense hot water at the click of a button. The purifier comes with two separate faucets for normal purified water and hot purified water. By default the water is heated to 45 degrees and if you have an option to raise the temperature up to 80 degrees. This feature is very useful, especially during winters. And the best part is, keeping the safety in mind, the purifier comes with a child lock button on the hot faucet to avoid accidental burns from the hot water.

Another one of a kind feature of AO Smith Z8 is the auto-flushing of the RO membrane. The purifier automatically flushes the RO membrane at the start of each purification cycle. This increases the life of the RO membrane and reduces the maintenance costs.
