i use mine on high all day then when the lights go off i turn it down to low my two cages are wrapped in shower curtain, and the humidifier is pointed at the curtain divider so it splits it into both cages... works for me. hope this helps
oh but you gotta stay on top of your filter they do get nasty after a bit and need to be replaced
Mine just has a water bottle you turn upwards on it and I use distilled water. Nothing for it to filter, but I do like the shower curtain idea. May add that into the plan of his big-boy cage.
