In 2024, the pricing of domestic RO membranes varies based on factors such as brand, capacity, and technology. Typically, high-quality membranes range from $30 to $150, with more advanced options featuring enhanced filtration capabilities priced higher. Membranes that offer additional benefits, like increased longevity or improved contaminant rejection rates, may command premium prices. Consumers should also consider the membrane's compatibility with their existing RO systems and potential replacement frequency when evaluating cost. As the demand for clean drinking water continues to rise, investing in a reliable RO membrane is essential for maintaining water quality and ensuring optimal system performance.
