My friend, you sir, are on point. My cool mist humidifier did absolutely fucking nothing....It didn't raise the RH level 1 damn i-ota, so I took it back last night thoroughly pissed off and just ran some vinegar through my old $60 warm mist humidifier and it worked like a charm last night. Cleaned it all out & got the scales off and then it ran all night and kept RH @ about 40% on average. In a nutshell, cool mist humidifier = ball sack...save your f'ing money.
