How long do you need to change an RO emebrane filter?

RO (reverse osmosis) membrane filters typically need to be replaced every 2 to 3 years. If the feed water contains high levels of contaminants like chlorine, hardness, or total dissolved solids (TDS), the membrane may need to be replaced sooner.

RO (reverse osmosis) membrane filters typically need to be replaced every 2 to 3 years. If the feed water contains high levels of contaminants like chlorine, hardness, or total dissolved solids (TDS), the membrane may need to be replaced sooner. Kaidefei is a professional RO antiscalant chemical factory, specializing in high-quality water treatment chemicals, including RO membrane treatment chemicals and polyphosphate antiscalants. Polyphosphate is produced through a phosphate chelant process, and as an efficient antiscalant, it helps extend the lifespan of RO membranes, especially in water purification systems.

Signs that indicate you need to replace the RO membrane:

1. Increased Total Dissolved Solids (TDS): When TDS levels rise, it means the membrane's filtering efficiency has decreased, and you should consider replacing it.
2. Decreased Water Output: A noticeable drop in filtered water flow suggests the membrane may be clogged.
3. Change in Taste or Odor: If the water develops an unusual taste or odor, it could signal membrane failure.
4. Increased System Pressure: If the time to fill the storage tank increases, the membrane may be compromised.
5. Frequent Filter Changes: If you’re frequently changing pre-filters and post-filters without improvement in performance, the membrane might be damaged.

Using Kaidefei polyphosphate antiscalants helps maintain the efficiency of the RO membrane system by reducing scale buildup and mineral deposits, extending the lifespan of both the membrane and the equipment. RO membrane treatment chemicals, like polyphosphate antiscalants, provide long-lasting protection for your water purification system.
