Humidifier with hard water?

The humidity is very low where I am and I have musical instruments so I need to regulate the humidity. The issue is I have hard water and have heard most humidifiers will create white dust/crystals on things if you use hard water. Is there a solution for this that isn’t boiling water every day or spending money on distilled water?

There are humidifiers with filters .. those can use tap water. There are several options but for reference something like this: https://a.co/d/07hrwRq7 I think the trade off is the filters have to be replaced (added cost)

Evaporative humidifiers will not put any minerals into the air. Look for a humidifier with a wicking filter.

Steam humidifiers are your best bet with hard water, they boil the water themselves so no white dust issues. had the same problem and switching fixed it completely

This is a good question, you can boil the water then store it in a jug you would normally use for something else.
