I purchased the travel Berkey as I'm only purifying for one and figured a 1.5 gallon reservoir was plenty big enough for me. I've watched most of the YT reviews and read the articles here on the product but I was curious as to first hand accounts of maintenance. Specifically, how often do breaking it down and clean the unit, and how long do you allow the water to sit in the base before you dump it or store it? I figure I'll use a quart for coffee each morning and drink the rest as is. The critter bowl may get topped up with it as well. Any info is welcome.
