Reverse osmosis membranes can be divided into many types according to the usage scenarios, membrane materials and processes. Different types of RO membranes differ in performance, durability and scope of application. Therefore, the membranes used in all RO equipment are not exactly the same.

The reverse osmosis system applies pressure to force water molecules to pass through a semi-permeable membrane, while impurities such as chlorine and fluoride are trapped on the other side of the membrane and removed.

Under normal circumstances, the replacement cycle of household reverse osmosis membranes is generally 2 to 3 years; the replacement cycle of commercial and industrial membranes is 1 to 2 years. Common household reverse osmosis membranes cost between US$30 and US$100...

The replacement cycle of reverse osmosis membrane is usually every 1 to 2 years. This is because over time, various contaminants such as heavy metals, minerals, pesticides, and salts in the water accumulate on the surface of the reverse osmosis membrane.
