Common Myths About RO Purified Water Busted

Reverse Osmosis (RO) is the most popular water purification technology globally, but it’s also surrounded by a lot of misinformation. Let’s clear up the facts.

Myth 1: RO Water is “Dead” and Lacks Minerals

Fact: It is true that RO membranes remove almost all dissolved solids, including healthy minerals like calcium and magnesium. However, the vast majority of our mineral intake comes from food, not water. Furthermore, modern RO purifiers come with a “Mineralizer” or “TDS Controller” that safely adds these essential minerals back into the water before you drink it.

Myth 2: RO Water Leaches Minerals from Your Body

Fact: This is a persistent internet rumor with no scientific backing. Drinking demineralized water will not strip your bones or organs of minerals. Your body’s kidneys perfectly regulate electrolyte and mineral balances regardless of the water you drink.

Myth 3: RO Purifiers are Only for High TDS

Fact: While RO is mandatory for high TDS water, it can also be useful for lower TDS water if there is a risk of heavy metal contamination (like lead, arsenic, or mercury). RO is the only reliable way to remove heavy metals.

Myth 4: Boiling Water is Just as Good as RO

Fact: Boiling water only kills bacteria and viruses. It does absolutely nothing to remove dissolved salts, heavy metals, pesticides, or physical dirt. In fact, by evaporating some water, boiling actually increases the concentration of these dissolved impurities!

Don’t let myths prevent you from securing safe drinking water for your home.
