I can tell a dramatic difference in the smell and taste of my water now. It is so clean! During filtering, the machine is louder than expected. I think initially it was quieter and now has gotten a bit louder after just a month.
This is perfect, however please consider my suggestion. I would love it if you would double the size with two carafes. It fits perfectly under my upper cabinets. But I would love to have a little more water capacity. We live in an area where the water is expensive, which makes this unit very practical for us. I love the AquaTru and so does my husband.
