Thinking further on this I would clarify that although I don't use fans at all, there is quite a bit of air circulation. Heating, cooling, people and pets all contribute to circulation. Plus a limited time when I am able to open windows and doors.
I have a whole house humidifier which activates when the furnace operates, and this does a fairly good job of keeping humidity in the 40's. Despite this I still have 3 portable humidifiers which run 24/7 in 3 rooms. I have noticed that certain orchids prefer higher relative humidity and grow vigorously if you can match these requirements.
