Best Alkaline water purifier

Before we begin, let us clear some of your doubts and questions related to alkaline water and alkaline water purifiers.

Why & when you should buy alkaline water purifier?

Naturally alkaline water occurs when water (such as river water) passes over rocks — like springs — and dissolves the minerals present in the rocks to increase its alkaline level. This means that for water to be more ‘natural’ is should be slightly alkaline in nature.

However, certain purification processes make water acidic. Hence, it becomes necessary to have alkaline water.

RO purification is one of the best methods pf water purifications. Water that comes out of RO is pure water with pH close to 7. However, as soon as this water gets in contact with air, it turns acidic in nature. This is because pure water absorbs carbon dioxide which reduces the pH of water to 5.5 or lower. This acidic water is hot good for health and it should be either neutral of slightly alkaline for healthy body.

This means that whenever you purchase an RO water purifier, it makes sense to check for alkaline feature.

Also, there are several benefits of alkaline water as per Ayurveda. Hence, if you are a believer of Ayurveda and want these benefits such as weight loss, then alkaline water purifier should be the right choice for you.

Other said benefits of alkaline water are:

  • Better metabolism and digestion
  • More energy
  • Slow aging and reduced bone loss

But what if the RO water purifier does not have alkaline technology?

If your RO water purifier does not have alkaline feature, then check if it has a mineralizer present in it. Mineralizer is a mineral cartridge that adds minerals into the water. Hence, you should check for mineral cartridge in your water purifier. Usually, mineral cartridge comes with magnesium and calcium ions. These two minerals are the biggest source of natural alkalinity in tap water, hence a mineralizer effectively reduces the pH of water.

How Alkaline Water Purifiers Work?

There are two types of alkaline water purifiers in the market.

1. Alkaline Water Purifier That Works with Electrolysis (alkaline ionized water)

The principle of alkaline water electrolysis is quite simple. When direct current is passed through water, the water gets split into two parts which are attracted by respective terminals- alkaline minerals and acidic minerals. The water with alkaline minerals is reserved for drinking, while the acidic water is removed.

This is not considered a very healthy method of producing alkaline water. Good news is that most water purifiers in India do not use this method to produce alkaline water.

2. Alkaline Water Purifier That Works by Infusing Minerals

As discussed, tap water is alkaline because of presence of calcium bicarbonate and magnesium bicarbonate, but since RO purification removes these minerals, the water turns acidic. Hence by adding magnesium and calcium into water. This creates hydroxyl ions that turn water alkaline.

These hydroxyl act as antioxidants that prevent oxidation and damage to the DNA.
