Highly recommend searching for "industrial humidifier" on whatever shopping platform you use. Pictured is one of the 5 gallon humidifiers we run in our 1600sqft shop. We have a couple of these going at all times, and despite being in a big room we are able to get the RH to 40% whenever we need.
We had a similar issue with "evaporative" humidifiers in the past. They don't do jack squat. You need ultrasonic humidifiers to make a dent in a large room. Ours puts 1 gallon of water per machine into the air every hour. One problem we're having now though is the dust from the minerals in the water. Our techs hate it. Want us to use only distilled but that's quite a pain. So far using demineralization cartridges in the water has helped a lot..
**edit: i am also from the cold north btw**
I ended up getting that same model, when the box came in I thought it was a mistake with it being so small. The pictures made it look bigger but it is putting out some water, running it for the first time today, will see how it does, currently at 24% humidity in that room, will see how much it raises it and how fast. Trying to find a spot where it is not near paper or the machines has been a challenge. It is almost like a fog machine running at full blast!
