Watched a couple of YouTube videos; unboxing/set up which helped me. I was amazed with what was left in the unit after use. I use vinegar to clean out after each use. It doesn't distil a lot at a time, but I wasn't looking for family size, just individual use. I also purchased trace minerals that I add back into the water before drinking, as that was highly recommended when I was researching distil units. Hope this information helps as you look to meet your needs. Best wishes!
