If you use a volcano style vapor cap, most of the water drops will be
trapped and fall back inside the unit, or into the water bowl. Water drops
are more likely to escape with the sideways tea-kettle cap.
If you do not use a vapor cap at all, the output will be very strong,
but some water drops may escape. We recommend having a towel
handy where you install the CleanPot, and turning down the intensity
if water drops escape into your environment.
