Then,we need to activate the Japanese membrane first. Activation method: Pour about 50 degree warm water into the bottle,and stay the water in the bottle for 4-12 hours,then the membrane is complete activated. If the problem still exist,it may be that the Japanese membrane is not fully activated. Repeating the activation operation a few times will solve it.
