I used to always think my tap water had a weird taste to it when it was room temperature.  I drink room temperature water because I have sensitive teeth. After using this filtration I now know why my water tasted funny.  After filtering it, it tastes so much better. I also love that the reservoir is so large. I fill it up, then after it filters I can fill up the upper tank. So as I drain the bottom, it refills with fresh purified water from the top! It also seems to purify the water faster then products I've used in the past.
