Best Water Purifiers in India

Choosing the best water purifier for your home can be a bit difficult due to lack of knowledge on the technologies a water purifier use.

So thought I would write up an article on this topic.

I will explain to you the technologies different water purifiers use and also tell you which is the best purifier for your home, based on the water which is available in your locality.

Complete Guide to Buying the Best Water Purifier

First, I will tell you a few things to keep in mind before buying a water purifier for your home. I would suggest you read the steps I had mentioned below to take the right decision.

I will list the things to keep in mind first, then I will explain in detail about each step. So that would make things simple and clear to you.

  1. Source of water coming to your home
  2. Hardness or TDS level of water you have
  3. Type of purifying technologies available
  4. Purifying technologies needed for you home
  5. After support provided by the Brand of water purifier

So let me start to explain in detail about each thing mentioned above.

Source of Water coming to your Home

The major factor in buying a water purifier is by knowing which type of water is used in your home. It is because water from different sources has a different level of bacteria or micro-organisms which may be harmful to your health and dissolved salts which are not required for your body.

The purifier must also help in removing the heavy metals like lead, arsenic, mercury etc from the water too. The heavy metals should be removed as it cannot be removed by the immune system and it will start accumulating in our body causing health problems.

Some water sources may contain very harmful bacteria, virus, and germs which may cause water-borne diseases like cholera, typhoid etc. I would prefer you to choose a water purifier by keeping all these in mind and don’t go for cheap and low-quality water purifier. It is matter of your health, my friend.

Just calculate how much you might spend on doctor fees and medications if you get ill. So choose wisely. Below I will provide you with details on the source of water, micro-organism level, hardness, of water etc. Details below are from water sources in India.

Underground or Borewell or Tanker Supplied Water

Harmful Micro-organism Level – Very High in Bacteria, Virus and other Germs

Hardness or TDS level – Hard Water and Very High TDS

Recommended Purifier – RO+UV Type

Underground or Tube Well or Salty Water

Harmful Micro-organism Level – Bacteria and Viruses are Low

Hardness or TDS level – High hardness and TDS level

Recommended Purifier – RO Type

Source from Surface Water like River, Lakes or Rain Harvesting Plans

Harmful Micro-organism Level – Low germs, bacteria and virus in water.

Hardness or TDS level – The water will be soft water

Recommended Purifier – UV or Ultra Violet Type

Hardness or TDS level of Water you Use

In the above table, I had mentioned a technical word that is TDS or Hardness of water. The full form of TDS is Total Dissolved Salts. TDS helps us to calculate the hardness and softness of water you use. The water we get from well or tank suppliers contains a lot of salts and impurities in it. These must be removed from the water as it is harmful to our body.

These impurities even include heavy metals like lead, mercury, and arsenic which is very harmful. The heavy metals cannot be removed by the immune system of our body, so we should purify the water from these and use. Stacking of these heavy metals in ou body may cause health issues and reduce our lifespan. These are very much harmful to children in long run.

This is where the RO purifier comes into action. The RO purifier cleanses the water and makes it fit for drinking.

So now, How to check the Hardness or TDS level of water manually?

To check the hardness and TDS of water you must buy a TDS meter which you can easily buy online.

Note: I would recommend you to buy a TDS meter, so that you can check the purity of water even after buying the purifier. This will give you an idea when to service your purifier.

Below is the TDS reading showing the purity and hardness of water, you can use to check.

TDS Reading and purity of Water you Use

0-80 – Ideal Drinking Water and Very Soft Water

80-15 – It is soft water and can be used for drinking

150-400 – Hard water and use an RO Purifier

400 and Above – It is Very Hard Water and uses an RO+UV Purifier

Purifying Technologies available in Best Water Purifiers

I will list down the best purifier technologies used and then explain about each of them.

Technologies available in the Best Water Purifiers:

  • RO or Reverse Osmosis Technology
  • UV or Ultra Violet Technology
  • UF or Ultra Filtration technology

Now, I will tell you in detail about each technology used.

1. RO or Reverse Osmosis Technology

This technology is used in water purifiers which are used to purify Salty, Hard and High TDS Level water. This technology converts high TDS and Hard water to water fit for drinking. In this process, water is passed under high pressure through a semi-permeable membrane to remove even minute impurities.

RO water purifier needs electricity and produces a lot of wastewater.

2. UV or Ultra Violet Technology

In this process, a rod is placed inside the body of water purifier which continuously produces Ultra Violet radiations. The UV radiations are made to pass through the water which destroys the germs in the water. This technology mainly helps in killing germs, bacteria, virus, and other microorganisms present in the water. They do not remove dissolved salts and impurities.

This technology uses electricity but they don’t produce waste water.

3. UF or Ultra Filtration Technology

In this process, threads of microfibers are used for filtration. Water will be passed through the microfibers threads which will remove the impurities like salt from water. This process is mainly from plants and trees which use its root fibers as filtering water.

Which Purifying technology do you need?

Guess you know the hardness of water you use now. You can check with these purifying technologies below. I had mentioned which is best for all kind of water.

  1. RO Water Purifiers: are used for purifying water with high salt which is harmful to health. They use a semi-permeable membrane for the purification process. I had mentioned about the RO technology in the above section.
  2. UV Water Purifiers: are used mainly to make the water germ free and fit to drink. UV Purifier keep us away from virus, bacteria, and other microorganisms which cause disease like typhoid, cholera etc.
  3. Water purifier using gravity: It is one of the best water purifier in India which don’t need any electricity. These are purely pressure, gravity, and chamber based technology. The water will flow from an upper chamber to lower chamber. In between the both chambers a germ killing kit will be fixed which purify the water. Gravity based water purifiers are good for purifying soft water which contains very low dissolved salts. You can purchase these purifiers at a very reasonable price ranging from Rs.1000 to Rs.4000.
  4. Technology Fusion: These are universal purifiers which use a fusion of technologies. All type of water can be purified by this kind of water purifier. It uses RO, UV, and UF technologies together to give you the best and clean water to drink. This water purifier is a fully automatic purifier which even checks the water level and uses the best technology needed for the type of water. Universal purifiers remove all germs and dissolved salts from the water.

Brand Genuity and After Support

The final and important step for buying a water purifier in India. After you decided which water purifier to buy, next is to decide which brand of water purifier to buy. Most of the people at this stage for go for the cheapest brand. My dear friend, when it is related to health go for the best brands. Small brands will be using cheap quality materials. So go for good brands.

After two or three months of purchase, you want to get the purifier serviced. This is the main reason I recommend to go for good brands. Big brands give you superb after sales support. Yes, it’s true it will cost a bit extra for the big shots but keep in mind it is worth it. Bigger brands also use high-quality membranes, filters and germ kills which run for a longer period.
