I had the same issue for years in the Midwestern US. I wasted a lot of money on the little 1 galon warm and cold mist humidifiers.

You need the type that uses multiple paper wicks (they look like air filters). I have one that uses 4 of these and has 2 big fans. It can burn through 4 gallons a day. It's not quiet but it does work.

And as a bonus you can use tap water without having to worry about limescale (it'll stay in the paper wicks which are replaceable anyway)
