We have lived in a very rural setting for the last 15 years. Our spring, which is very productive, has always been unusable for drinking or cooking due to poor taste caused by brine and other byproducts of oil and gas wells adjacent the property. I had been hauling gallon jugs of water from my workplace for all these years. Then we bought the incredibly affordable PureMaster V-750 whole house filtering system. At a fraction of the cost of a reverse osmosis system, this unit has transformed this horrible water into good tasting water that can be accessed from our tap. We can't tell you how pleased and amazed we are at the transformation that has occurred as a result of the installing of this extremely affordable and effective system!
