Loooooooove our Berkey.
I don't know what size we have; it's been 10 years since we bought it. We don't change our filters often enough, and I rarely clean it
but it is hands down the best water I've ever had. I fill 3 32 oz thermoses every day when I go to work so I don't have to drink the water there. (I drink a lot of water, LOL.) The water in the Houston area is HORRIBLE. Like, in restaurants where it isn't filtered I can't even drink the sweet tea because it tastes so bad. It's the only reason I drink soda when we go out to eat - but there have even been places where the soda tastes bad!
