The best humidity solution I've found is to set my shower up as a humidifier. Puts out a lot of humidity that spreads throughout the house. Doesn't need any cleaning, refilling, etc. Total cost on Amazon, like $40 (probably cheaper from Home Depot). Picture of my setup: https://imgur.com/a/Oca4USg
I did that with 4-5 products: A shower head splitter, a shower->hose adapter, a mister, and anti-leak tape.
The larger humidifiers come with a humidistat which will keep humidity within say a 5% range. A solution like this may over humidify and requires more frequent intervention.
