The only 2000 gallon capacity carbon block water filtration system with LED display telling you exactly how many gallons have been used and when to replace the filter.More than 60% of the population doesn't drink the recommended 8 glasses of water a day. Yet those that do see a 50% decrease in cancer. So why don't more people drink water? Simple. Pour yourself a glass of water straight from the tap. Once youtake a sip you'll probably cringe at the putrid taste and then gag as you notice a bunch of little floating micro pollutants swirling around your glass. And the alternative, bottled water is expensive. That's why a quality water filter is sucha great solution. There are plenty of water filters on the market but none of them tell you exactly how many gallons have been used. A warning alarm even sounds as a reminder at the end of the filter's life cycle. This is important becauseaccidentally using a filter beyond the recommended life cycle can be hazardous to your health. Many people don't realize that mold and bacteria can build up in an overused filter, causing serious health risks. Most common filters on the marketalso have a very low capacity. That's where they get you. Having to replace a filter every 300 to 500 gallons can really run up a bill. And most use inferior granulated charcoal filters. We only use a top of the line NSF certified (themost important healthy seal of approval) solid carbon block filter. That means a broader range of dangerous particulates are removed from your drinking water.
