To help promote betterhealth, the Samsung water filter removes unwanted particles from your water. However, it does not sterilizeor destroy microorganisms. You will need to purchase a water purifying system to do that. In order for theicemaker to operate properly, water pressure of 138 ~862 Kpa is required.
