If you can swing it get a whole home humidifier. Game changer and only requires one filter a year with basically zero maintenance.

Otherwise get something evaporative and that is rated for more than the space you need. Otherwise it will run at max speed and is usually nosier, requires more fills, and you will likely use a lot more power too.

Also, clean the filer every week or two, wash the bottom out, and flip the filter over. It will significantly increase the lifespan.

FWIW I’ve needed a humidifier for over 30 years and can think at least 8 different ones I’ve owned. Finally bought a house and it already had the whole home one installed. So much nicer.
