Review: Great Filters - Works great. I buy all my water drop filters in advance and as soon as I install a new one I order a replacement. So easy to install.
Review: Easy to use, water tastes great. - We've been using the Waterdrop RO system for over 5 years now with no issues (with the main unit). Filter changes are super easy and quick. Water tastes great. A little pricey up front, but with 1:1 water use, you'll save money on less waste water. Waterdrop customer service was quick to send us a replacement faucet (LED filter ring failed). Very pleased and expect this unit to last 5 more years.
