>I use a humidifier, but don’t want the humidity going up past 60%
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.
The Pacific Northwest, where today’s humidity is 70%.
However that’s basically irrelevant because the place I rent has a 20+ year old central heating and cooling system, so inside the humidity can drop below 40% and I’ll get painfully dry sinuses and nose bleeds.
55-60% is my own comfort zone
In cold climates the humidity can drop to uncomfortable levels during the winter (sub 30% where I live). Especially when combined with wood fired stoves.
