Check out the Points When you Need to Change Your RO Membrane and Filter

TDS (Total Dissolved Solids) Levels: TDS refers to the amount of dissolved solids in the water, including minerals and salts. Over time, the RO membrane may become clogged with these dissolved solids, reducing its effectiveness. If you notice an increase in TDS levels, it may be time to replace your RO membrane.
Water Flow Rate: If you notice a decrease in the water flow rate from your RO system, it could be due to a clogged filter or membrane. In this case, you may need to replace one or both components.
Age of System: The age of your RO system can also indicate when it's time to replace the membrane and filter. Most RO membranes and filters need to be replaced every 2-3 years, so if your system is approaching this timeframe, it's worth considering a replacement.
Water Quality: If you notice a change in the taste, odor, or color of your water, it may be an indication that the RO membrane and filter are no longer functioning correctly. In this case, it's essential to replace these components to ensure your water remains safe and clean.
Maintenance History: Regular maintenance of your RO system can help prolong the life of the membrane and filter. However, if you haven't been performing routine maintenance, it may be time to replace these components sooner rather than later.
