Technical Note: PureSure Extends The Life Of The Purification

In a conventional water purifier, when a purification pack, fed with RO permeate with a conductivity of 35 µS/cm at 1.5 to 2 litre/minute has reached the stage when output water quality drops below 18.2 MO-cm, it is necessary to change the cartridge, in order to maintain water quality. At this point, only about 40 to 45% of its total ion exchange capacity has been used up.
