Review: Great filter for a great value - Seems to work great and at a fraction of the cost of the major brand name.
Review: Water Tastes Great! - The taste of our water has improved greatly since utilizing this water filter. We found that we do need to run at least 1-2 gallons of water through the new filter before the water tastes the best to us, but we use those first couple of gallons to water plants, so it's not just running down the drain. This water filter has been a great addition to our house I will definitely purchase this water filter again.
