I have had this dispenser for over a year, and I am really pleased with the quality of the filtered water. I have only one complaint: sometimes the water takes a long, long time to flow from the upper compartment, through the filter and into the lower area. I installed a new filter, but no change, very much to my surprise. I did an online chat with a customer service person, who said it can be caused by an air bubble in the filter. I tried squeezing the filter as suggested, but the problem persists.
