Best Water Purifier in India

We have been testing Kent RO water purifiers since 2016. Previous models like Kent Pearl, Kent Grand have a faulty design. The components are not tightly packed in those models, so many users complained about cockroaches entering the machine.

Over the years, the design has improved a lot. For example, the Kent Supreme extra comes with a Food Grade Plastic Body, and the components are push-fit which means the purifier is leak-proof.

Coming to the Purification Process, this Kent model comes with a 7 Stage purification process That Includes treatment of the water by Reverse Osmosis, Ultraviolet Bulb, and UF (UltraFiltration) Chambers.

8 things to keep in mind before buying a water purifier

While you might feel that it is so simple to buy a water purifier on an e-commerce platform to pick your brand and place your order in order, the fact is that before you select the right water purifier for your home, you have to take many factors into account.

These factors also vary by region, which should change your preference further. Then, of course, the mumbo jumbo marketing doesn’t make much difference. Here are five things to consider before you go and buy a water purifier for your home in this context.

Water Quality

This is the most important thing to check before you decide on your home water purifier. Water will probably be hard water in your home, meaning there are many TDS or Total dissolved substances. The TDS measures the combined dissolved content of all organic and inorganic substances in a liquid. This may be in suspended molecular, ionized or micro-granular shape. In potable water, the WHO recommends an allowable TDS limit of 50-120 mg / l to pH above 7.4.


Contamination is the second factor to consider when purchasing a new water purifier. We refer to the presence of heavy metals such as plum, arsenic, magnesium, copper and iron through contamination. These heavy metals can be toxic in large quantities. Industrial waste is often referred to as the source of heavy metals.

Water pressure

Water pressure is an extra factor in determining the right filter for your water purifier. When you have a high pressure of water, a reverse osmosis water purifier works well. It is advisable to pressure 5 to 40 pounds per square inch or psi for such a system. Companies recommend using a booster pump fitting on the RO system for homes with low water pressure. You can also decide on an activated Carbon Filter if your water supply has low TDS.


Many electric water purifiers are not functioning without electricity so that it is terrible in areas with continuous power cuts. For example, if you do not have electricity, a UV filter won’t work because it uses power for the UV lamp. Likewise, the electrical power in the RO is used for activating the RO membrane. But an activated carbon filter system or an ultra-filter works without electricity, but sediments can only be eliminated from the source of your water.

Daily Usage

The average daily water consumption for your family is also a consideration. You must first decide if you need a cleanser for the drink or the whole house only. Figure out consumption once you know the requirement. You have to purchase a high power and high-performance module if your daily water consumption is increased. As a thumb rule, the output of a water purifier should not be less than the number of people in your home within a single hour.


Once you know your intake and the cleaning technology you want, it’s worth a budget. A smartphone that you update once or every other year is not a water purifier. It is a long-term investment, and similar funding is needed. We would therefore recommend a personal brand. You will have to spend at least Rs 7 000 – Rs 8,000 on a water purifier with the reliability and type of filter you plan to obtain. The cost of a RO water purifier will rise (more on this later).

Maintenance Cost

A household appliance is a water purifier which results in maintenance costs. To maintain the whole system, the filter is changed and maintained. Thus, every three to four months, you have to consider the cost of servicing the appliance. In addition, the filter needs to be replaced annually. A good cleaner usually has about 2 000 Rs a year in maintenance cost, but it can reach as much as 5,000 Rs. Some enterprises have annual maintenance agreements, which may, in the long term, be cheaper.


It may not come to your mind when you buy a purifier of water. However, it’s a critical point as you buy a water purifier every 8 to 10 years. You do not have to buy a new water purifier if you move to a new place, and somewhat your current water purifier will be removed. You must look at the body and the portability and weight of a water purifier. An additional bonus, which might add to your kitchen aesthetic, is a good-looking water cleansing.

Frequently Asked Questions

How does a water Purifier work?

Now I will discuss the flow charts, electric circuits, electrical problems and maintenance tips for your UF/UV purifiers. But, first, let me remind you that ultrafiltration is UF, and ultraviolet radiation stands in this case between 190 and 400 nanometers.

First of all, let me come to a standard UF/UV purifier, dividing the components into two groups. One group has to do with filtration and the other with the operation.

Filtration Process: The UF/UV purifier filtrating process comprises components such as the inline filter for sediments (5 microns), the inline activated carbon block filter, the UF Membrane Cartridge the UV Cartridge for Disinfection.

Electrical operation: In the electrical function and storage are involved components, such as Adapter, Float switch, Solenoid Valve Ultraviolet Lamp, and Storage Tanks.

Which is the best water purifier to buy?

The above mentioned are tested purified which are the best-selling in the market. So please select one of them according to your range and requirement. The definition of the best water purifier in India is the mixture of mineral booster + TDS controlled (To provide the essence of both natural and purifier water) + Copper (For health benefits) + water heater.

Which water purifier is suitable for drinking?

The ideal pH level for drinking water is 7. The water purifier that can give you pure drinking water without eliminating the basic TDS levels and healthy minerals is the AO smith green series.

Is RO water harmful?

The significant drawback of RO water is that it also clears out healthy minerals and harmful hard metals during the purification, reducing the nutritional value of drinking water, which is not suitable for health in the long term. Therefore, always opt for a purifier with a RO+Mineralizer+TDS controller.

How do I choose the best water purifier in India?

  • Check the TDS level of water in areas you live in.
  • Choose the type of water purifier with features according to your TDS levels.
