Hi Matt, 7 just bought my second complete Santevia and a back up 5 stage filter. I will not be without it!!. I have had this system for over 7 years. I was helping Lily MacD clean the bottom tank and dropped the filter - it broke- from a fall of 3 feet onto a ceramic floor. Oops, well I was reading the directions for assembly and noticed 2 things: 1:-#3 says scrub gently the video shows briskly. Anyway, maybe the next printing of the pamphlet can have adjustments. 2- #5 says boil 1 minute, the video says 2. I added a minute to the joil and will rescue the ceramic to activate it. Be well and thank you.
