What are the disadvantages of RO water?

Author: scraper  |  Last update: Tuesday, August 11, 2026

Reverse Osmosis (RO) water offers excellent contaminant removal, but it has notable downsides. It strips away beneficial minerals like calcium and magnesium, creates substantial wastewater, and results in slightly acidic, flat-tasting water. Additionally, RO systems require frequent maintenance and can be expensive to install.

What happens if we drink RO water every day?

Most healthcare experts agree on this: RO water is safe to drink daily if it's supplemented with essential minerals. A mineral cartridge or TDS controller in your RO system can solve the problem easily. People with kidney issues or those on sodium-restricted diets may benefit from RO's low-salt output.

In order to control this problem, the NGT had issued the ban on RO water purifiers in areas which had piped water supply TDS levels lower than 500 mg/litre.

Can RO water cause joint pain?

Usage of RO system leads to demineralization of water specifically calcium and magnesium which leads to increase prevalence of coronary heart disease, joint pain and back pain and this deficiency cannot be compensated by diet. Therefore, our discussion is based on demineralized water and CHD, joint pain, and back pain.
