Life for RO membrane
- The important role of domestic RO membranein water purifier
The RO membrane is the core filtration unit in a household water purifier. It effectively removes
heavy metals, residual chlorine, bacteria, viruses, and various organic impurities from the water,
ensuring safe and healthy water. The condition of the RO membrane directly determines the quality of your family's daily drinking water. If the membrane becomes clogged or its performance degrades, the overall effectiveness of the water purifier will be significantly impacted, even if the other filter elements are intact.
- Normal service life of RO membrane
Generally, the lifespan of an RO membrane is approximately 2-3 years. However, this lifespan is
affected by water quality, frequency of use, and regular maintenance habits:
- If the local water quality is poor, with high levels of sediment and residual chlorine, the RO
membrane may need to be replaced within 1.5-2 years.
- If the water quality is good and the frequency of use is moderate, the RO membrane may last for more than 3 years.
- If household water consumption is high or the water purifier is operated at full capacity for
extended periods, the lifespan of the RO membrane will be shortened.
- Signals that the RO membrane needs to be replaced
To determine whether an RO membrane needs replacement, consider the following:
- A significant decrease in water output, resulting in increased scale buildup in the kettle;
- A change in taste, with the water having an unpleasant odor;
- The membrane has not been replaced for more than three years;
- A continuously increasing TDS value indicates decreased filtration performance.
