Which type of water purifier is the best water purifier for India? We asked this question to a water treatment technician and here is what he said:
“As a father and a water purification technician, I often recommend UV water purifiers over RO water purifiers. UV water purifiers are an excellent way to meet our families needs for water purification. When used in conjunction with a pre-filter and post-filtration, UV light is an excellent method to purify tap water at home. Most importantly, it retains the natural PH, alkalinity and minerals in the water; making it the safest purifier water to drink.”
However, if the input water at your home or office is hard or has high level of dissolved solids (TDS), then you must use a Reverse Osmosis based water purifier.
In this article, we will discuss about the different types of water purifiers available in market, their pros and cons, and the top 5 best water purifier models under each of those categories.
We hope this guide will help you determine which water purifier is right for you.

Looking for best water purifiers within a certain budget? Check out the following posts on our website:
Which Water Purifier is Best for You
Largely, there are three main types of water purifiers that you can install in the kitchen. These are: Gravity based non electric water purifiers, UV water purifiers, and RO water purifiers. All of these water purifiers disinfect the water but not all of them will work with all types of water. To decide which one is the best water purifier for your needs, its important that you know pros and cons of each type of water purifier.
Gravity Water Purifiers
Gravity based water purifiers rely on gravity for water purification. You have to manually pour water into the upper tank of water purifier. This could be cumbersome especially for the busy or elderly people.
Further, the gravity based water filters are suitable to purify water with TDS or total dissolved solids content less than 500 mg/liter. This means it will not be suitable to purify bore well water that is muddy or rusty in color. In several cities tap water is full of chlorine and fluorine among other salts making such water unsuitable for gravity water purifiers.
Gravity based water purifiers are good to remove bacteria, protozoa, cysts and any turbidity in water. However, it can not remove viruses, heavy metal or chemical content in your water. Some gravity water purifiers come with silver impregnated activated charcoal filter that can remove some chlorine from water.
UV Water Purifiers
Similarly, if the water you need to purify has high TDS then even the UV filters may not be able to work effectively. This is because the micro-organisms that are stuck or hidden behind suspended particles in water will escape the UV rays and will therefore not die.
However, the UV water purifier models that come with a pre-filter and a UF cartridge are good at eliminating all micro organisms from the purified water.
A UV water purifier that comes with a pre-filter and a UF filter is suitable for purifying water with TDS upto 500 mg/liter*.
The 2 main advantages of a UV purifier over gravity water purifier are:
- It is more effective at killing germs
- These water purifiers are fully automatic.
Is UV Water Purifier Good Enough?
Many people like to go for a RO water purifier, irrespective of whether they really need a RO or not. This is because they are simply following the trend and are not aware of the potential health effects of drinking de-mineralized water.
The problem with RO purifiers is that they waste too much of water, they are costly to maintain, and they can cause mineral deficiency in body if TDS level is not maintained in the purified water.
RO Water Purifiers
RO water purifiers on the other hand don’t face any of these problems and provide you with water which is as pure as distilled water. But the problem with RO water purifiers is not purification, but the un-natural character of water that is produced after multiple stages of purification process.
This problem happens where people install RO Water Purifier for purifying water that has TDS of less than 500. In such cases, the TDS in purified water reduces to less than 50 mg/liter.
Such water is un-natural and not found in nature. Not even in Himalayas. In nature, water always have some TDS in it, which includes minerals, bicarbonates, and other substances. Such water is alkaline and is best for human consumption.
To fix this problem, latest RO water purifiers come attached with an alkaline mineral cartridge, or TDS adjuster, or both. This process adds important minerals like calcium, and magnesium back into the purified water and also improves the taste of water and its PH value.
RO Ban – National Green Tribunal Vs RO companies
In the year 2019, National Green Tribunal ordered prohibiting the use of reverse osmosis (RO) purifiers where total dissolved solids (TDS) in water are below 500 mg per litre. RO manufacturers moved supreme court but the court refused to stay NGT ban. Instead it directed RO manufacturers association to approach the government for resolution. Government is currently, talking to all stake holders and will soon make a law for RO Water Purifiers.
Because RO water purifiers are not environment friendly and waste too much of water during purification process, it is therefore highly unlikely that RO Ban will be lifted until RO water purifiers become more environment friendly.
This gives us another reason to prefer a UV water purifier over a R.O. water purifier. Especially if the TDS in your water is less than 500mg/liter.
RO won’t be banned in cities/areas where TDS in water provided by water agencies (Jal Boards) is over 500mg/liter.
