10 Best Water Purifiers in India 2023

Water, the essence of life, is an invaluable resource that keeps all living organisms on our planet alive. However, pollution, industrialization, and population growth have all harmed the quality of available water. Basically pure and healthy water is a basic necessity for humans. It is needed to be treated, purified and made fit for usage and drinking.

Water purifiers are machines designed to achieve that precisely. Today, water purification has reached astounding levels of technology and relies on multiple stages of filtration. Naturally, choosing a water purifier for home becomes very confusing. Therefore, after reviewing various products, we present to you our list of the 10 Best Water Purifiers in India 2023.

Before we jump straight into the best water purifiers we need to understand first what are the technologies working behind a water purifier.

RO vs UV vs UF vs MF – The Different Purification Technologies

RO (Reverse Osmosis): This is among the most common methods for purifying water. Water is purified using membrane technology, which removes dissolved salts, bacteria, and other impurities. The membrane, which separates germs and dissolved chemicals from water, has fine pores that allow only water to pass through while trapping all harmful chemicals and microbes. Also It reduces TDS up to 90%.

UV (Ultraviolet): This method uses UV light to eliminate germs and bacteria. 99.99% of the harmful organisms in the water are destroyed. A small lamp inside the purifier emits small UV waves, which destroy the bacteria and viruses in the water. However it cannot remove dissolved salts or harmful heavy metals. It makes almost minimum reduction in TDS.

UF (Ultrafiltration): Another purification method that uses membranes similar to RO, These membranes remove impurities such as particulate matter, pathogenic organisms. A UF water purifier physically removes all germs and bacteria and filters out all visible and suspended impurities such as mud, rust, dirt, and sand from drinking water. It makes almost No reduction in TDS.

MF (Micro Filtration): Depending on the intensity and level of impurities, standard RO water purifiers can waste up to 80% of the water during the purification process. MF is a system that balances that out by eliminating water wastage, and does not require as much maintenance as RO filters. It makes almost No reduction in TDS.

Which is the best water purifier in India?

When it comes to the best Indian water purifier, AO Smith Z9 Hot+ Normal RO, KENT Supreme Alkaline Water Purifier, Livpure Glo Star RO, and Sure From Aquaguard Delight are some of the obvious choices. However, that’s not all. In order to know more, do check out this article as we have covered the 10 Best Water Purifiers in India 2023. 

Is RO water 100% pure?

Yes, RO water is almost 100% pure. Reverse Osmosis (RO) water purifiers filter out chemicals, dissolved impurities and heavy metals like Lead and Arsenic which are invisible to the naked eye but capable enough to cause diseases. Thus, making the water fit for human consumption.

What is TDS in a water purifier?

Total Dissolved Salts (TDS) is the concentration of solids or dissolved particles in water. The salts include calcium, magnesium, bicarbonates, chloride, sulphates, and many other dissolvable impurities. TDS is measured in PPM (Parts Per Million). Water with a TDS level between 50 ppm -150 ppm is considered healthy for drinking.

What is the disadvantage of RO water?

Excessive purification of water removes essential minerals like Calcium and Magnesium from it. These minerals are necessary for the growth and well-being of our bodies. This is the disadvantage of RO water. However, today’s advanced water purifiers come with mineralizers which ensure that your drinking water has the necessary amount of essential minerals.

Which is better: RO or UV filter?

While an RO water purifier removes dissolved impurities from water, a UV water purifier disinfects water by killing harmful germs and microbes. Thus, if the TDS level of water is above 500, then an RO water purifier would be the perfect choice. The RO system will eliminate dissolved contaminants and unnecessary substances. However, water with a TDS of less than 500 will require UV purification to be safe for consumption. 

Which brand of RO water purifier is best?

AO Smith, Kent, Aquaguard, Livpure, HUl Pureit, and V-Guard are some of the best brands known for RO water purifiers. In addition to that, Eureka Forbes water purifiers have been quite popular too in recent times.
