5 Best Water Purifier in India | RO, UV, UF, water purifiers | Ultimate buying guide


Last Updated on November 20, 2021

Why we need water purifier? the answer is to drink safe, polluted free and mineral added water. Before further proceed, we have to analyse or check our source water quality with the help of TDS meter. What is TDS? TDS (Total Dissolved Solids) represents the total concentration of all the dissolved substances in water. It measure of dissolved minerals, salts, metals, and impurities in the water. You can easily check the initial TDS level of source water in few seconds only.

Here are the best TDS meter available in the market.

The ideal Range of TDS is between 100 and 300ppm. In some scenario less than 500ppm are also acceptable but if TDS is more than 1000 ppm, the water is dangerous and unsafe. If the TDS level goes down below 100 ppm is not ideal as it is devoid of most minerals. So keep this in your mind.

Ideal Purification technology for different TDS range.

  • If TDS level is below the 300ppm then go with UV+UF water purifier technology
  • TDS level of your source water is higher than 300ppm, go with UV+UF+RO technology.
  • TDS is greater than 2000- Domestic Water Purifier cannot be used. Buy a water softening solution.

In my research UV+UF purification technology are enough for most of the families and it full-fill our most of the criteria. I choose UV+UF over RO because RO purifier decrease the TDS level below the 100ppm which is not good for out health and it also waste too much water. If your source water TDS level is higher then you should go with RO purifier. Here are our top 5 best water purifier in India you should check out.

How can I choose best water purifier ?

Purification technology

Generally, there are four types of water purification technology in India- Non-Electric water purification, RO (Reverse Osmosis) purification, UV Water purification technology and UF purification.

  • Non-electric or Gravity water purification – It is a non-electric water purification tech that have 7-stage purification process. The cartridge filter the harmful disease-causing bacteria and viruses and also removes the suspended impurities and organic chemicals.
  • UV water purification – It use UV light to kill micro-organism bacteria or germs upto 99.99%. It don’t add any chemical and don’t change the test of water. It is also known as E-Boiling
  • RO water purification – RO purifies can remove heavy metals, dissolved salts, bacteria and other impurities from the water, particulates, and minerals through selectively permeable membranes. It has fine pore which allow only water to pass through. There are a term called “Multi-stage RO purifiers” which can quickly remove water impurities like mud, sand, bacteria, viruses, excess dissolved solids like calcium, magnesium, and heavy metals like lead, arsenic, etc.
  • UF Purification – It remove impurities like particulate matter, pathogenic organisms, etc with same RO purification technology. A UF water purifier works by physically removing all the germs and bacteria present in drinking water.

What is alkaline water? and How it benefit for you health?

The “alkaline” in alkaline water refers to its pH level. The pH level is a number that measures how acidic or alkaline water or any substances is on a scale of 0 to 14. For example, something with a pH of 1 would be very acidic and something with a pH of 13 would be very alkaline.

Normal drinking water generally has a neutral pH of 7. Alkaline water typically has a pH of 8 or 9. Because alkaline water has a higher pH level than does plain tap water, proponents say that it can neutralize acid in your bloodstream, regulate the pH level, slowdown the aging process, it also increase the viscosity of the blood which benefit Diabetes patient, blood pressure patient. However, research suggests that alkaline water is unlikely to significantly change blood pH.

What is MTDS?

MTDS or Manual TDS regulator is a small device that lets you adjust the TDS level of an RO system.

What is e-boiling?

UV Purification also known as E-Boiling, this method uses UV light to kill germs and bacteria. 99.99% of harmful organisms present in the water are destroyed.

What is Hydrogen water?

Hydrogen water is a water that contain additional hydrogen molecules. There is limited scientific evidence that hydrogen water has any health benefits in humans, although its proponents make claims it provides such benefits as functioning as an antioxidant, reducing inflammation, reducing risk of metabolic syndrome, providing neuroprotection for various diseases, and reducing side effects associated with cancer radiation treatment.
