Debunking Common RO Purifier Myths

Dec 11, 2017

We all are aware of the rise in water pollution across the world, and everyone agrees to the threat it poses to our health and well-being. However, when it comes to using water filtration technologies, there are a number of confusing ideas, myths and opinions floating around. While experts agree that Reverse Osmosis or RO water purifiers are among the best water filtration products available today, there are several claims to the contrary as well.

In this post, we will analyse and debunk several prominent myths surrounding RO water purifiers.

Myth 1: Reverse Osmosis Removes All the Minerals from the Water

Not true, Reverse Osmosis works by forcing raw water through a number of filters to produce clean drinking water. The filters remove silt, hard particles, odourants, chlorine molecules, ions, calcium and magnesium particles and other harmful substances from the water in the different stages of filtration.

Typically, the water from our tap or water source contains very small amounts of minerals (not enough to benefit our body in any reasonable way) and most of them are in an insoluble form. This means even if ingested, these minerals will be discarded as waste. Therefore, it is a myth that RO water purifiers remove minerals from the water, instead they remove harmful metals such as lead from our water to make it safe for drinking.

Myth 2: RO Water Purifiers Waste a Lot of Water

RO Water purifiers discharge some water when filtering raw water. This waste water is produced when the membranes are rinsed for removing the left-over contaminants after clean water is stored in the purifier’s tank. The process helps in prolonging the life of the osmosis membranes and filters. It also ensures that the contaminants do not mix with clean water when the next RO cycle begins. However, the waste water discharge by RO water purifiers is quite negligible and those concerned can put it to a variety of uses, such as watering the plants or pre-washing utensils.

Myth 3: RO Drinking Water is Acidic

Again, it's just a scare tactic. RO water purifiers remove bicarbonate crystals from the water but cannot remove carbon dioxide particles, which means there is some acidic content left in the water. While ideally drinking water should have a neutral pH, tap water generally has a pH of 7. The pH levels of RO water ranges between 5-6, which is not that much more than the pH of Coffee which is 4. Therefore, the acidic content if any (as it depends on pH levels of tap water as well), is negligible at best and doesn’t cause any harm to our body.

Myth 4: Softened Water from RO Leaves a Slippery Film on the Skin when used for Face Wash or Bathing

Another myth which has caused panic among many users, however, the thin film experienced by some people when using RO water for face wash or bathing is just the skin which has been cleaned and moisturised. Generally, hard water elements such as calcium and magnesium prevent the soap from cleaning the skin properly, but softened water lets the soap clean off the dirt and grime, making your skin feel smooth to touch, which some people mistake with being a slippery film.
