(Last Updated On: November 18, 2022)

If you are planning to buy a water purifier or thinking to replace your old one with a new purifier, then this buying guide will help you out. The reason behind writing this buying guide is that I have received many emails from people who were confused about what points to consider while buying a purifier. Many were going for an expensive option, whereas some did not even know the basic thing about a purifier and yet were planning to buy it!

Water Purifier in India is not “good to have” but its a “must-have”, given the kind of urbanization and pollution we are facing as we grow as a nation. while we all are hopeful that things will be better but as individuals and families, one must give maximum focus on the purity of the water you are drinking. Water can become a source of multiple health issues if you are not drinking pure water.

What is a water purifier?

A water purifier is an appliance that eliminates contaminants from the water in order to make it safe for humans to consume. It removes all kinds of impurities from the water such as dust particles, suspended solids, dissolved minerals and more.

This device helps in killing all the germs, fungus, bacteria, and viruses from the water. There are different types of purifiers available in the market, which are different from each other on the basis of their functionality and the technology they use to purify water. A water purifier uses different filters to remove all types of impurities from water.

Water Purifier Buying Guide

Know about your tap Water Quality

The first step is to understand the kind of water that comes into your house. The water at your tap may be sourced from lakes, rivers or other natural sources, or it could be supplied directly from municipal lines. Depending on where you live, the quality of water available for consumption varies drastically. To find out what kind of water you get in your house, get a lab test done. This will give you a detailed idea about the condition of your drinking water and what contaminants might be present in it.

Purification Technology

Understanding your source of supply will help you choose the right technology that is used to purify the water. There are different types of purification technologies available in the market today like UV (Ultra Violet), UF (Ultra Filtration), RO (Reverse Osmosis) and more. There are also multiple variants within each of these technologies based on additional features and benefits they offer like energy saving, mineral booster, etc.

Select Right Size/Capacity of Water Purifier

Water purifiers are often referred to by the capacity of their water storage tanks. The most common capacities available in India range from 5 liters to 10 liters. You need to keep in mind that a family of 4-5 people will require at least 15 liters of purified water every day, so a 7 or even 10-litre storage tank will not be sufficient. If you are looking for an efficient water purifier, it’s important to consider the number of hours per day you spend at home and how much-purified water is required during that time.

While choosing a size, keep in mind that you’ll need about 5 liters for drinking and cooking purposes per person per day. For example, a family of 4-5 people should opt for a 10-15 liter capacity.

Types of water purifiers

UV Water Purifier

A UV system uses a UV lamp that emits a short-wave ultraviolet light that is lethal to bacteria and viruses. The UV light destroys the microorganisms by penetrating their cell walls and altering their DNA structure. It renders the cells unable to reproduce, thereby preventing them from infecting other organisms.

UV Water Purifier is one of the most popular choices for home and commercial use. Most of the UV water purifiers come with various features, such as auto cut-off, TDS controller, digital display, and others. We have compiled a list of the best UV water purifiers available in India along with their features.

Their only downside is that they cannot remove dissolved contaminants like pesticides, salts, heavy metals or chlorine from water. So if you have a major source of contamination in your tap water like dissolved salts or heavy metals, then you will have to use them along with RO or UF type filters.

RO Water Purifier

Reverse Osmosis (RO) is an effective technique used for removing unhealthy contaminants from water. This technology works on the principle of osmosis which states that if two solutions with different solute concentrations are separated by a semi-permeable membrane, then solvent molecules will pass through that membrane to equalize concentration on both sides.

The major reason for using RO water purifiers is the removal of dissolved impurities, salts, heavy metals and harmful chemicals. However, it also removes essential minerals from the water. To add back these minerals some RO water purifiers have an additional feature of a mineral cartridge.

This type of purifier can be used in areas where there is a large concentration of dissolved solids (beyond 500 ppm) and salinity in water.

UF Water Purifier

Ultra-filtration is a method where water passes through a membrane having pores that are in the nanometer range to remove microorganisms from the raw water without using chemicals or electricity. Thus, filtered water has a high purity level and can be used for drinking purposes.

UF removes particulate matter and bacteria from the water. This type of filtration is perfect for purifying brackish water and surface water. Most of the UF membranes come with 5-micron pore sizes that can filter out particles as small as 0.01 microns. These filters are capable of removing 99% of all bacteria, viruses, and cysts from the water.


These types of water purifiers have a combination of all three technologies and are considered one of the most effective waters purifying methods in India. These types of water purifiers remove both dissolved impurities as well as harmful bacteria and viruses from contaminated water and make it fit for consumption. The RO membrane removes heavy metals like lead, arsenic, etc. The UV lamp kills any existing microorganisms in the water and UF removes suspended impurities to further make it fit for drinking purposes.

How to select a water filter Based on TDS Level

Well, we recommend you should decide on RO or another type of Water Purifier based on TDS Level. We recommend following the below metric to arrive at which type of water Purifier will best suit your need.

For this you should first buy a TDS meter from marker or order online, these are fairly cheap and can be used in the future as well whenever you want to measure the TDS level of your drinking water.

  • When TDS is less than 200: Go for UV, UF Water Purifier
  • For TDS is greater than 200:  go for RO Water Purifier
  • TDS is greater than 2000- A typical Domestic Water Purifier will not help here you should buy a water softening solution.

What is Reverse Osmosis (RO) in water Purifier

Reverse osmosis consists of guiding the flow of water towards a semi-permeable conduit that is responsible for retaining the larger molecules. Osmosis filtering systems allow the elimination of almost 100% of contaminating agents from the water, but it must be taken into account that they can also prevent the passage of healthy substances such as magnesium or potassium. To solve this problem, the most recommended alternative is activated carbon filters, which ensure the elimination of contaminating particles but allow the passage of healthy minerals.

Comparing Different Water Purification Techniques Pros and Cons

Filter Method Pros Cons
Reverse Osmosis (RO) The water obtained is very clean and can be used to transform non-potable water into potable water.

The filter only requires replacement every 12 months (this differs depending on the brand and the degree of use of the filter).

  • Expensive to install and maintain compared to faucet and pitcher filters.
  • It spends up to 5-6 times the consumption of water.
  • It removes many of the desirable minerals from the water.
  • It has difficulty removing or reducing calcium and magnesium – the minerals that make water hard, so pre-softening may be required.
UV water purifier
  • Very effective in eliminating bacteria and viruses.
  • Reliable and economical (the lamp is changed annually).
  • Clean (no “dirty” or contaminated parts to throw away).
  • It cannot be used on its own in most cases. It does not remove other contaminants from the water, such as heavy metals, salts, chlorine, or artificial substances such as petroleum products or pharmaceuticals.
  • UV light is only able to work if the water is clear. If the water is cloudy or contains “floaters”, a filter must be used beforehand; UV light cannot effectively reach microorganisms because the rays are blocked by the other particles.
  • Primarily a disinfectant that effectively kills biological contaminants.
  • It oxidizes and precipitates iron, sulfur, and manganese so that they can be filtered.
  • Oxidizes and breaks down many organic chemicals including several that cause taste and odor problems.
  • More expensive than the other technologies.
  • Unstable oxygen (ie ozone) acts as an oxidant in the body and can contribute to cell damage, aging, disease, etc.
ion exchange
  • Does not need electricity.
  • Fast flow rate.
  • Ideal for household filters.
  • It does not effectively remove particles, pyrogens, or bacteria. High cost over time.
  • There is no scientific proof that alkaline water is better for your health.
  • Removes a wide range of contaminants.
  • Reusable process
  • Do not remove bad taste/odor. It consumes large amounts of energy.
  • The system usually takes up a lot of counter space.
  • The water does not contain minerals or salts after distillation.
  • It does not necessarily remove pesticides and herbicides.
  • It does not require any special equipment.
  • It greatly reduces the risk of getting sick in the short term.
  • It does not remove many contaminants, such as metals.
  • It is a very costly method in money and time for large volumes of water.

Final Thought on best RO in India

In case you still don’t own a water purifier, I think it’s high time you should get one. Water Purifier is a must-have in India, even if you are consuming borewell or Municipality water. Soil and Waterbody Pollution in India makes it almost unfit for direct drinking.

In case you don’t want to invest in a water purifier, I suggest you should boil your drinking water, at least it will kill the majority of germs and bacteria.  To removed metal impurities, it may still require proper filtration methodology to make them fit for drinking

You can refer to our recommendation to make the best choice before buying a water purifier.
