For those looking for an effective water purification method, reverse osmosis is always a favorite choice. It is a widely used water filtration system that is highly efficient in eliminating all kinds of impurities such as chemicals, bacteria, viruses, and other contaminants. But, one common question that surrounds this system is – does reverse osmosis remove minerals? As a dedicated plumbing service provider, we have conducted extensive research to help you understand this better.

What is reverse osmosis?

Before diving in, let us learn what reverse osmosis is. Reverse osmosis is a method of water filtration wherein tap water is passed through a semipermeable membrane that traps particles, impurities, and minerals. The purified water is then stored for immediate use. There are some downsides to the over purification, it removes the essential minerals that our body needs, such as calcium, magnesium, sodium, and potassium.

Yes it removes minerals from water

The answer to the question is – Yes, reverse osmosis does remove minerals from water. However, on the positive side, you can still obtain these essential minerals from other sources such as food, supplements, and multivitamin capsules. It is pertinent to note that the amount of minerals eliminated varies depending on the system being used. In other words, it is possible to mitigate the loss of minerals by tweaking the water filtration system.

In-line remineralization filter

Some users prefer to use an in-line remineralization filter to prevent the total removal of minerals. This filter contains mineral beads, which are added to the water filter system. During the water purification process, the beads release essential minerals including calcium, magnesium, and potassium. This helps maintain the natural taste and balance of minerals in drinking water.

It is a known fact that drinking mineral-free water is not a severe health issue. However, it is equally important to understand that certain minerals help improve digestion, regulate blood pressure, and strengthen bones. Therefore, choosing a filtration system that purifies water without stripping away minerals is always a better option.


To summarize, reverse osmosis is a highly effective water filtration system that does remove minerals from water. Although mineral-free water may not cause harm to our health, it is crucial to maintain a balanced intake of these essential minerals. To achieve this, consider incorporating a mineral bead filter in your reverse osmosis system or opt for a filtration system that retains the minerals in the water.
