out of curiosity, what part of the globe do you live (or when was your home built) that you need a humidifier? I have a dehumidifier as it is quite often > 50% humidity in my home, easily as much as 65%, but that's due to the high humidity outside where it can easily be 85%. Just looked at my sensor, it is currently 81% outside and 55% inside. That 55% is where it really starts to become uncomfortable. I struggle to keep it <50% inside. At these indoor humidity levels, it limits some of the things that I can do indoors as it has a negative affect on things I make/do. So adding humidity is just one of those things that makes me tilt my head sideways and go huh? like a dog because it is so out of my experience.
