Is RO purifier bad for health?

Drinking clean, safe water is essential for good health. However, the quality of tap water can vary depending on where you live. Some areas have water that is contaminated with harmful bacteria, viruses, or chemicals. Others have water that is hard, meaning it contains high levels of minerals such as calcium and magnesium.

If you are concerned about the quality of your tap water, you may be considering installing a reverse osmosis (RO) water purification system. RO systems are designed to remove impurities from water, making it safe to drink. However, there is some debate about whether or not RO water is actually safe for human consumption.

How RO Systems Work

RO systems work by forcing water through a semi-permeable membrane. This membrane allows water molecules to pass through, but it blocks larger molecules such as bacteria, viruses, and chemicals. The water is then filtered again to remove any remaining impurities. The resulting water is typically free of harmful contaminants, making it safe for human consumption.

Potential Health Risks of RO Water

While RO water is generally safe to drink, there are some potential drawbacks to consider. First, the process of reverse osmosis can remove beneficial minerals from the water. These minerals, such as calcium, magnesium, and sodium, can be important for human health. In addition, some studies have found that water that has been purified through reverse osmosis can have a slightly acidic pH, which can be stressful on the digestive system.

Another potential issue with RO purification systems is that they can remove beneficial bacteria from the water. These bacteria, such as probiotics, can help the body to stay healthy. Additionally, RO systems can remove fluoride from the water, which is important for dental health.

Finally, there is the potential for contamination from the reverse osmosis system itself. If the system is not properly maintained, it can become a breeding ground for bacteria, mold, and other contaminants. These contaminants can then be introduced into the drinking water, potentially causing health issues.

Is RO Water Safe to Drink?

The evidence on the safety of RO water is mixed. Some studies have found that RO water can have negative health effects, while others have found that it is safe to drink. Ultimately, the decision of whether or not to drink RO water is a personal one. If you are concerned about the potential health risks, you may want to consider other methods of water purification, such as distillation or carbon filtration.


Reverse osmosis systems can be a great way to ensure you are consuming the cleanest, safest water available. However, it is important to consider the potential health risks associated with consuming water that has been purified through a reverse osmosis system. If you are concerned about the quality of your drinking water, you may want to consider investing in a quality filter system or test kit to check for contaminants. Additionally, it is always a good idea to discuss any potential health concerns with your healthcare provider.

Here are some additional tips for ensuring the safety of your RO water:

  • Install a pre-filter on your RO system to remove larger particles and contaminants.
  • Change your RO system’s filters regularly, according to the manufacturer’s instructions.
  • Inspect your RO system regularly for signs of leaks or damage.
  • Store your RO water in clean, airtight containers.
  • Drink RO water within a few days of filtering it.

By following these tips, you can help to ensure that your RO water is safe to drink.
