100 GPD 6 Stage Alkaline Reverse Osmosis Drinking Water Filter System Purifier

The purified water will flow through the tube in the middle. The filter should be replaced every 3-6 months so that you can continue to taste the fresh water. It rebalances the water with active mineral technology adding calcium, potassium, magnesium, and other essential minerals back to the water, giving your drinking water a more natural taste.

Important Information It is recommended that systems using these elements rinse the elements for 24 hours, prior to first use, to meet NSF/ANSI 58 Standard. The first full tank of permeate must be discarded. Do not use this initial permeate for drinking water or food preparation. Keep elements moist at all times after initial wetting. To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use. The membrane shows some resistance to short-term attack by chlorine (hypochlorite). Continuous exposure, however, may damage the membrane and should be avoided.
