The reality of Reverse Osmosis Water, RO Purifier

Clean drinking water is difficult to come by. In third-world countries like South Korea where poor infrastructure and lack of proper resources to provide potable water. And even in our own homes, tap water toxicity is a real concern. Tap water includes arsenic, mercury, lead, copper, microorganisms, and numerous kinds of bacterias, fertilizers, and medications. These chemicals and particles slowly poison you because our liver and kidneys cannot get rid of it. Some techniques like reverse osmosis and ultrafiltration are followed to get rid of these harmful particles, but these techniques are really helpful for us? Let’s understand the reality of the reverse osmosis water processes in detail.

The popularity of reverse osmosis water (R.O. water) has steadily grown since it was first introduced as a home water purification system in the 1970s. Reverse osmosis systems use pressure to push water through tiny pores i.e. semi-permeable membrane, to create pure water. In the process, chemicals, and minerals are filtered through different membranes, and carbon filters depends on the size of the contaminants. In general, if the contaminants are larger in size than water molecules, those contaminants will be filtered out. If the contaminants are smaller in size, they will remain in the drinking water.

Is RO water safe for drinking? – Reality of Reverse Osmosis Water

This is a very controversial topic in the water world. Just about everyone knows that RO systems removing water impurities, but few are aware that they also remove the beneficial minerals. In fact, the reverse osmosis (RO) process removes 92-99% of beneficial calcium and magnesium.

There are numerous scientists and researchers Claims that RO water is not good for health. Scientists and researchers worldwide have repeatedly demonstrated that long-term consumption of reverse osmosis (RO) water is bad for your health. There are mainly three points, i.e.

  1. The reverse osmosis process removes all essential and harmful particles from water so has no essential minerals in RO water.
  2. The second disadvantage claimed by some is that RO water is Acidic and thus is not good for health.
  3. RO water is not good for health because it is too pure like distilled water.

Another side of this topic claims reverse osmosis water is safe for a normal healthy person, According to, Consumption of low-TDS water, such as that which results from RO treatment, does not pose any health concerns for healthy populations. Essentially, in normal, healthy individuals, the body is able to maintain homeostasis, which is what controls the release and adsorption of minerals, regardless of the TDS levels in the ingested fluids. is reverse osmosis?

Reverse Osmosis and Distilled Water:

RO water and distilled water both are demineralized. Theoretically reverse osmosis water systems strip everything out of the water except for H2O molecules. RO and Distilled water typically have around the same amount of impurities on a TDS scale i.e. from 5–40ppm (parts per million).

How Could RO Water Possibly be Unhealthy?

The primary argument behind theory seems to be based on one study released by the World Health Organization (WHO). WHO produces international norms on water quality and human health in the form of guidelines that are used as the basis for regulation and standard-setting world-wide. There are a few health issues and the harmful effects of RO water consumption:

How Could RO Water Possibly be Unhealthy? increased morbidity and mortality from cardiovascular diseases, pregnancy disorder and risks of motor neuronal disease.
Increased morbidity and mortality from cardiovascular diseases, pregnancy disorder, and risks of motor neuronal disease.
  1. It has been reported by WHO and other studies that drinking demineralized water can cause electrolyte imbalance in the body.
  2. Magnesium plays an important role in glycolysis and ATP metabolism.
  3. It has been found that drinking low or no magnesium water for the long term can cause increased morbidity and mortality from cardiovascular diseases, pregnancy disorders,s and risks of motor neuronal disease.

Which Filteration is Suitable for Normal Water?

It is not safe to drink the water that directly comes from your sink tap or by applying RO water purification process. Both are harmful to our health. If you are using an RO water purifier, there needs to be some other technology that will help in maintaining the essential minerals lost during the purification process. Another technology like Ultrafiltration is best if your tap water quality is good having a TDS level is less than 500.

Is it Good to Install Reverse Osmosis System?

Before installing RO system in your home, check your tap water quality in terms of the TDS level. If your home water TDS level is less than 500, installing RO system could decrease your water TDS level to 5-40 ppm, which is not good for our health. According to researches, the permissible TDS level for drinking water is 50-150, less than 50 is very harmful. Here below the reality of reverse osmosis water, RO water:

  1. Reverse osmosis is a way of filtering water that removes not only harmful particles but also filters out minerals that is good for our health. Minerals are essential to our cellular metabolism, growth, and vitality.

  1. Reverse Osmosis may reduce pH levels somewhat as it removes healthy and unhealthy inorganic minerals from tap water.
  2. There’s no real way for reverse osmosis to filter out harmful ingredients and leave good ones (minerals) in.
  3. The reverse osmosis process also wastes a lot of water and electricity.
  4. Unfortunately, removing all of the minerals, vitamins and other god ones from your water supply can impact your health by leading to mineral deficiencies
  5. Reverse osmosis can be a good option if you live somewhere with super contaminated water having a TDS level of more than 500ppm or as a short-term solution, like when you’re camping.
  6. Ultimately, the right decision is the one that works best for your family. Never believe in cheap RO filtration that claim UF, UV, and RO filtration, they are using low-quality parts/components or filtration level that may play with your health you’re your family life. Good luck!
