WATER PURIFIER: Are you finding a water purifier? Is it right to drink Mineral water? Leave all this. Is the water purified by RO, UV, UF, or MF actually clean water?


RO is a good filter technology but for 1L pure water, it wastes 3L water. It eliminates minerals like Calcium, Magnesium, and Sodium. Therefore it is not a safe technology. You get merely a liquid and not water. Buy an RO when it is absolutely necessary.

UV Filters

Next comes UV filters that kill germs, dirt, and bacteria. Neither do they disturb the taste of water nor do they change the color of the water. They are very cost-effective.

UF Filters

UF water purifiers remove even dead bacteria and germs from the water.

The only downside of the UF filters is that they aren’t able to remove the dissolved solids in the water.

MF- Micro Filtration System.

The Micro-Filtration system removes all the suspended and visible impurities like mud, dirt, sand, rust, etc. from the water. However, MF purifiers cannot remove dissolved salts or harmful metals.

Then comes the biggest marketing gimmick- TDS Controller. Where ever you find TDS or MTDS is written, remember there is strong marketing going on there. TDS adds impure water to pure water to increase or decrease the TDS levels. We highly recommend you stay away from purifiers with TDS or MTDS.

“According To WHO- 3000 ppm TDS (Total dissolved solid) can be consumed directly without any filtration.”

“According to BIS (bureau of Indian Standards) 500 TDS water can be consumed without any filtration.”

We recommend you follow WHO’s guidelines and use a good purifier

  1. If the TDS level of water is 250-300 then you don’t need RO. You must buy a purifier with a UF+UV combination.
  2. If the TDS level is above 300, then you must buy a RO+UV+UF combination.

You can check the TDS level by using a TDS meter that costs INR 250. Check the TDS level before buying RO. Unnecessary cleaning will turn the water into merely a liquid. Minerals are essential and mineral-free water is just a liquid, not water.
