The water reaching our homes is generally contaminated with various harmful pollutants, including chemicals and microorganisms rendering it toxic for human consumption. Unfiltered water possesses millions of these toxic particles, which are detrimental to health. In order to get germ-free clean and safe water for drinking, water purifiers are your best bet.
Different purification technologies are required to remove chemicals and microorganisms from water and make it safe for consumption. Water purifiers using a single technology do not suffice the purpose. You need a purifier that uses double purification technology of both RO and UV/UF technologies to get rid of all pollutants and make water absolutely safe for consumption.
The best water purifier, however, is one with RO+UV+UF+ TDS because the water dispensed by the RO purifier rips the water of all essential minerals. Having a TDS controller ensures that essential minerals are retained in the water and it also makes the water taste better.
Reverse Osmosis (RO)
Reverse Osmosis is a water purifying technology that makes use of a semipermeable membrane for filtering out all the chemical pollutants. It is a very sensitive membrane through which water is passed at high pressure to filter out all molecules, ions and other larger particles and only the water molecules are able to pass through it. Thus, the TDS (Total Dissolved Solids) of water gets reduced and all harmful chemicals, including cadmium, arsenic, lead, mercury, etc. get eliminated from the water.
Ultraviolet Purification/Filter (UV/UF)
Ultraviolet purification technology removes all microorganisms like bacteria, viruses, and cysts by penetrating through them and rendering the micro-organisms incapable of multiplying by attacking their genetic core. Its double layer adsorbent carbon filter adsorbs the foul taste and smell of pesticides, VOCs and other organic impurities.
In a purifier with double purification technology, as both RO and UV/UF are present, no chemical or biological impurity can pass through and thus the filtered water is absolutely safe and clean for consumption.
However, as RO technology eliminates all chemical impurities, even the essential minerals that are required by the body gets eliminated. The water tastes flat and is not considered healthy. To overcome this shortcoming, it is recommended to buy water purifiers with TDS controller. In this kind of purifier, a mineral fortification cartridge is present at the last stage of the purification process, which adds the essential minerals back in the water. This augments both the taste and quality of water and thus makes it safe for consumption. The water also attains back the essential minerals, which are required by the body and hence this water is considered the best to consume.
Keeping all these things in mind, it turns out that purifiers with double purification technology are a compelling buy in today’s scenario. This is because water today is not contaminated by a single source but multiple ones including both natural and man-made, more so by human activities.
Buying a purifier that’s capable of removing both the chemical and biological contaminants using its double purification technology is thus the safest bet.
