The selection of water purifier depends on the availability of quality of water in your city. India is diverse geographically and in term of availability of water as well. Many cities are located near sea, many are near lakes, rivers and many on hilly area.
Each of the water sources is having different properties. Therefore, it makes sense to select water purifier based on type of water in your area.
A water purifier which is best suitable for treating physical parameters of water like high TDS, may not be equally suitable for the treatment of microbiological parameters. A water purifier which your cousins are using in Delhi is not need to be necessarily meant for you, living in Mumbai.
You can’t purify something if you don’t have any idea that what needs to be purified.
So before purchasing, out of the given list of best water purifier available, it is important to go for some warm-up task.
If you are in hurry and have basic understanding of water purifier type and their functionality, you can skip this warm-up task section and you can go for one of the following water purifier which is very much suitable for most of houses in general.

Warm-up task before selecting water purifier
Get your water tasted
If you really want to be sure of the quality of water you are drinking and get your pre-buying research done effectively to buy the most suitable water purifier, then the first thing to do is to test the water you receive at home.
This isn’t a difficult process.
You can contact water testing labs in your city. See if they have sample pickup service or not. Otherwise you can deliver water to their lab as per their instruction. Once they are done with testing,they’ll let you know the results.
In such testing three parameters are checked mainly
- Physical parameter (TDS, TSS, color, odor, taste etc.)
- Chemical parameter (pH, Hardness, Alkalinity, COD, BOD, pesticides etc.)
- Microbiological parameter (E. coli, coli form, toxicity taste, plate count etc.)
The list of water testing labs is available on website of Ministry of Drinking Water and Sanitation.
In case you cannot take your water sample to lab, consider booking an appointment on Purity Portal. They offer doorstep sample collection at nominal cost.
If the lab taste results are within permissible range, then for you even basic water purifier will do the work. No need to put unnecessary expenditure on your head.
In most of the cities we get municipal water. Municipal water is considered good to consume but comes with inherent risk of supply through corroded pipes, regular cleaning of storage structures etc. So having a basic water purifier here also is quite beneficial.
Selecting Water purifier Technology
Reverse Osmosis (RO) purifier
Reverse osmosis (RO) is a water purification technology that uses a partially permeable membrane to remove ions, unwanted molecules and larger particles from drinking water.
This is the most commonly use tech in water purifier and indeed most effective also. The term RO has become synonym with water purifier now a day, thanks to the marketing strategy of some brands. Find out detailed functionality of RO purifier.
RO Water Filter Requires electricity to operate and requires relatively high maintenance.
Ultraviolet (UV) purifier
The Ultraviolet (UV) Purifier uses the UV Rays to kill the Bacteria, and other microorganism present in the water.
In UV technology a high dose of ultra violet light energy at a wave length of 254 nanometers destroys microbes. The UV waves affect the DNA of microorganism and prevent multiplication of micro-organisms. Because of this within 20 to 25 minutes time microbes present in your water die completely.
UV energy adds nothing to the water or does not generate any byproducts, neither does it changes Water chemistry.
UV Water Purifier requires electricity, but it doesn’t need additional power to boost the Tap Water Pressure. It can work with Normal Tap pressure.
Ultra Filtration (UF) purifier
Ultra filtration (UF) uses home water pressure to push water through a semi permeable membrane which removes any contaminants. Unlike reverse osmosis, ultrafiltration retains minerals in the water, while filtering out bacteria, viruses, and parasites.
It does not need electricity to operate and works well with the regular pipe water pressure.
