1. Keep the membrane element moist after use;

2. Because the membrane element contains a protective liquid, the water produced within the first hour of use should not be used;

3. Customers should not add other chemicals that could damage the membrane element when using it, as this will seriously affect the quality of the element.

4. Customers should store the RO membrane in a dry box at room temperature to avoid damage caused by low temperatures and high heat. If the polyethylene bag is broken, it should be refilled with a protective solution and vacuum packed to avoid microbial growth.
