Reverse Osmosis Systems That Remineralize Your Water


Reverse osmosis (RO) uses pre and post-filters and a semi-permeable membrane with micro-pores to efficiently filter out viruses, bacteria, and chemical contaminants. One downfall is that RO systems also remove the healthy minerals in the water, leaving it slightly acidic. Remineralizing RO water is the ideal solution for adding essential minerals and improving the pH of drinking water.

Reverse osmosis systems fitted with a remineralization filter can add minerals into the water after it has been decontaminated. These systems are also able to reduce the acidity of reverse osmosis water.

This post highlights the benefits of remineralized water and discusses the top RO systems capable of remineralization in detail.

Benefits of remineralized water

According to the WHO, demineralized water is not ideal for drinking. This is because demineralized water doesn’t provide adequate levels of naturally found essential minerals.

Remineralizing your RO water assures your family access to pure, refreshing, and tasty water with beneficial nutrients like calcium and magnesium.

Substantial evidence shows that consuming magnesium-rich water significantly reduces the risk of Cardiovascular disease (CVD) and CVD fatalities.

While, drinking water low in calcium is associated with a high risk of fracture in children, low weight at birth, certain cancer types, and cases of CVD.

Thus, water remineralization following reverse osmosis is vital for the general health of your household. It guarantees the presence of essential minerals and improves water pH.

Can you remineralize RO water?

Remineralizing filters do a fantastic job of adding healthy minerals to your RO water. Investing in an RO system that can remineralize your water is the perfect choice for healthy, pure drinking water.
