Best Water Purifier for Homes in India

To decide on the best water purifier for home in India there are a lot of parameters to look for,  like water TDS, water supply, types of purifiers available, and also a few other things. In this article we will go through some of these.

As a starting point, you will need to know more about the source of water to your home as only then you will be able to decide on the kind of water purifier that will be the most suitable for your home. To test the type of water supply at your home there are various methods available that use the TDS meter, and allow you to submit a sample of your water to a laboratory to test it. Water testing kits are also available.

Following are some of the simple water testing methods:

1.      The TDS meter will let you find out the amount of total dissolved salts in your water supply. Water with a low TDS level is suitable for drinking. You can also use the HM-TDS-3 water meter for checking the TDS level.

2.      You can use the water testing kits available in the market. These water testing kits take approximately 24 hours to report the presence or absence of germs or viruses  in the water.

3.      The above tests may be more than reliable in informing you about the quality of water, but if you are still not very satisfied you may visit the nearest laboratory and get the water sample tested.

There are four different types of water purifiers available in the market

1. Reverse osmosis water filter These water purifiers are optimal for water that has a high level of TDS, ranging between 500 to 2000 ppm. RO purifiers are most commonly used in houses because they are able to remove all the different kinds of impurities from water such as bacteria, dissolved salts, and germs.

2. UV or ultraviolet purifiers–Ultraviolet purifiers are best suited for treating water that may contain viruses, bacteria, or the microorganisms that may cause different waterborne diseases.

3. Universal water purifiers–The universal water purifiers have a combination of different purification techniques like the UF, UV, RO, and activated carbon that can provide almost 100% clean and pure water.

4. Gravity water purifiers– The gravity-based purifiers make use of gravity to clean water. They are most suited for water with low levels of TDS or if you are looking for a low budget buy.  Their prices range between Rs. 1000 to Rs. 5000. Most importantly, they can function without electricity which RO and UV filters need. Gravity-based water purifiers may not be as effective as the ones that run on electricity and hence they are not suited for water supply which has a lot of impurities.

Other than the above points, there are certain other things to look for in a water purifier:

1.      All the different types of water purifiers like UV, RO, or the universal water purifiers need a continuous and steady electricity supply to function effectively. Some of these water purifiers come with a built-in water tank that is capable of storing filtered water, and can be useful even at times of electricity failure.

2.      All the water purifiers whether electric or not, do require regular maintenance. Hence, it is imperative to check for the company profile and also the different reviews and ratings online to get a good sense of the service support. The RO water purifiers require an extra pump if there is not enough pressure in the water supply.

3.      The RO UV water purifier suffer from a significant disadvantage in that they filter only half the water and waste the other half. For example, for every 2 litres of water filtered the output is only for 1 litre and the other 1 litre is wasted in the process.
