Which Water is Better: RO or Alkaline?


When it comes to our family’s health, we leave no stone unturned in giving them the best food, clothing, and facilities. But when it comes to choosing the right water for your home, the question of RO vs alkaline water comes into your mind. Let us settle this debate once and for all. Read on to know the difference between alkaline and RO water and which one you can opt for at home.

What is RO Water?

RO literally stands for ‘reverse osmosis’. This is a water filtration process that removes impurities from tap water up to a particle size of 0.0001 microns with a semi-permeable membrane. Hydraulic pressure is applied on equipment that forcefully separates impurities from water. You can compare this to the size of human hair which has a thickness of 3-4 microns.

This process effectively separates chlorine, microplastics, parasites, bacteria, lead and other heavy metals, dust and dirt, and other harmful impurities from water, making it absolutely clean for consumption and daily use.


  • RO water is one of the few sources that is purest and cleanest keeping water-borne diseases at bay.
  • It is free of disease-causing bacteria and fungus, thus keeping your immune system healthy.
  • Water tastes well as it does not contain salty minerals that give a distinct sour and salty taste to water.
  • Since it does not contain unsolicited levels of sodium, it keeps your blood pressure in check.
  • It improves your digestive health, kidney function and effectively hydrates your body.

What is Alkaline Water?

Water that comes into your home is slightly acidic in nature due to its source of origin. Alkaline water has a slightly higher pH, or potential hydrogen, which makes it basic on a pH scale of 1 to 14. While normal water has a pH of 7, the pH of alkaline water ranges anywhere between 8 to 9.

Your body has an excellent in-built mechanism to maintain a healthy pH of 7.3 to 7.4. However, modern lifestyle, pollution, and unhealthy habits often disrupt this normal process as your body has to work extra hard to maintain a balanced pH. This might cause a falling pH below the required levels leading to alkalosis. At this point, alkaline water does its best job of maintaining the required pH.

Benefits of Alkaline Water

  • Since alkaline water is full of essential minerals and anti-agents, it keeps your immune system healthy and has anti aging properties.
  • It keeps your skin healthy and hydrates well.
  • Alkaline water has been found effective against cancer.
  • It helps minimize acid reflux symptoms.
  • It helps detoxify the acidic waste that accumulates in your body due to unhealthy eating habits, insufficient exercise, and other environmental factors.
  • It helps with weight loss.

Which water is Better for Consumption? RO vs Alkaline

As far as the debate between RO and alkaline water is concerned, alkaline offers greater benefits to your body. This is because in RO with impurities, there are possibilities of essential minerals being filtered out via membrane. Alkaline water, on the other hand, keeps these minerals intact. Also, RO water is slightly acidic as compared to alkaline water.

Regardless, both the water sources are equally good for your health and you can choose the one that suits your preferences and budget. RO water purifiers will be easy on your pockets as compared to alkaline water purifiers.

How to Get Best Quality Alkaline Water?

You can easily source naturally alkaline water if you live near water bodies. However, those living in metropolitan cities, generally get tap water which is then filtered via a machine. You can purchase either a RO water purifier or an alkaline water purifier as per your requirements. However, a few water purifiers from the one like iLiv, give you the benefits of both, RO as well as alkaline.
