In recent years, with the continuous breakthroughs in domestic membrane technology, long-acting RO membranes (reverse osmosis membranes) have become the focus of industry technology. At present, mainstream brands have launched RO membrane products with a service life of 3-5 years and a total net water volume of 8000-12000L, effectively reducing the average annual cost of core replacement for users.
