What is an RO water purifier, and how does it work?

An RO (Reverse Osmosis) water purifier makes use of a semi-permeable membrane to remove dissolved impurities, heavy metals, and contaminants from water. By forcing water through this membrane, harmful substances are filtered out, ensuring that only clean and pure water passes through. This method is highly effective in reducing TDS (Total Dissolved Solids) and eliminating pollutants, resulting in safe drinking water.

Why is it important to check the TDS level of water before buying an RO purifier?

Total Dissolved Solids (TDS) level serves as an indicator of the amount of dissolved solids present in water. Elevated TDS levels can alter the taste and quality of water, potentially containing harmful substances. Understanding the TDS level is essential for selecting the correct RO purifier with sufficient purification capacity to effectively diminish these impurities, ensuring the safety and pleasantness of drinking water.

What are the benefits of a multi-stage purification process in an RO purifier?

A multi-stage purification process combines various technologies like RO, UV, and UF to provide comprehensive water purification. RO removes dissolved solids and contaminants, UV kills bacteria and viruses, and UF filters out additional particles. This ensures that the water is not only pure but also retains essential minerals, offering enhanced safety and taste.
