We now have 2 of these tanks and can't live without them. We are soon to be a family of five and I have peace of mind knowing that the water my kids drink is lead, mercury and chromium free. The dispensers are great quality and easy to clean. I've tried many other filtration systems in the past and nothing compares to this filter. I also appreciate that the company sends these filters to schools in Flint, MI and other communities with unsafe drinking water. We're ZeroWater lifers.
