So I have used a large 2000+ square foot humidifier only it really is nothing more then a swamp cooler so if trying to keep the room with my instruments in it at 40-45%, which is a constant battle, if it is off an hour the room drops 10%, it is also cooling the damn thing down and causing the heat to run more. My room was at 43% the temp was 60F and the heater was on all the time. So I give up that POS is going to the garbage I will sit tubs of water out and put a fountain pump in them to help with humidity and have a little decoration without the constant swamp cooler effect so for the rest of the winter all instruments remain in their cases. Oasis humidifiers in a few and the rest a good old soapbox with a sponge, which actually seems to work really well. all the sponges and soap boxes were less expensive than one oasis set up. But now one day without the humidifier the house is down to 20% humidity very dry. There has to be a better way, to humidify without the swamp cooler effect.
