Decoding the best RO water purifier

It is a well known fact that water is essential for our survival.  According to researchers, the Earth contains about 70% water. Only a small portion of this huge percentage is actually fit for consumption, which is not enough for us. Availability of clean drinking water has become a luxury for us and it is imperative that we do everything in our power to conserve it. Water which comes from a conventional source comes with a lot of risks and health hazards because it contains some impurities like nitrates,  phosphates, heavy metals, microorganisms and dirt.

The first and most obvious benefit of having a water purifier is that it will eliminate the impurities that can damage your health. Water which goes through a purifier will contain lesser bacteria, fewer heavy metals and lesser chemical pollutants as compared to water that comes straight from the tap. Technology has gifted us many inventions that have made our life easier, simpler and flexible. Reverse Osmosis water purifier by Kent too is a gift of technology. It is an eco-friendly water purifier that saves water on the go. It is widely considered as the best RO water purifier in India.

Reverse osmosis technology pressurizes and passes impure water through a semi-permeable membrane. RO technology is probably the best purification technology known to mankind. It effectively removes all harmful micro-organisms such as bacteria, viruses and cysts. When it is used in combination with other filters (sediment and carbon), it successfully removes all other suspended impurities from water including dissolved gases and organic impurities.

The biggest advantage of this technology is that it is able to remove more than 99% of dissolved impurities such as chemicals, rust, salts of heavy metals, pesticides and insecticides present in water. In fact, RO is the only affordable technology that can remove dissolved impurities from water.

RO technology removes substantial amounts of most inorganic chemicals such as salts, metals and
minerals; micro-organisms and various organic chemicals. The quality of the membrane and the pressure of the water helps in determining how effectively the water separates form these contaminants.

However, RO devices have a drawback. Their process is so efficient that all the dissolved salts (minerals) from the drinking water are filtered out, including the essential ones necessary for our body. Water purified through only RO technology is distilled, has a bitter taste (because of no essential minerals) and has pH value lower than 7 - making it slightly acidic.

Further, RO technology uses a very fine membrane which has a pore size of 0.0001 micron. The process requires raw water to be forced at a very high pressure so that water passes through the small pores of the membrane, preventing bacteria, germs and other impurities from passing through. However, due to variation in day and night temperatures, high speed and pressure, some of the pores of the membrane get enlarged after a few months of continuous use. Thus, allowing harmful micro-organisms to easily pass through it and thereby making the process ineffective in the long run.

Kent has come up with a unique solution for this problem – the ‘Kent Mineral RO’ water purifier. This water filter uses a combination of RO+UV+UF+TDS to provide the cleanest water possible. Other innovative products by Kent include portable water purifiers, Tap guard, etc.
