So I've done some searches and have not found the answer I was looking for, so my question is, is anyone using humidifiers for their snake rooms?

I have a temp controlled snake room, the temps hover between 80-82 F. The only issue is humidity, it's hovering around 3O% in the room. The snakes are in tubs and I'm able to keep them around 50%, which is fine, but I'm getting a BRB this weekend, so I was hoping to boost the over all humidity in the room, so it's easier for me to keep the humidity in the BRBs tub up. I plan on using moss and moss hides as well as a big water dish, but I'd like the overall in the room to be a bit higher.

So again my question, what, if any, humidifiers are you guys using? I think there are two types, cold mist or warm, I'm wondering if anyone has experience using either style or if anyone has a specific brand or model they like. Thanks!
