I have these humidifiers. I have one in my living room but it still says it’s only 19% humidity.. I use faucet water, should I use distilled water or what could I do for it to work better ?

I’m also getting another humidifier for my dining room since my living room is right next to it and I have a sorta big house. Just looking for opinions to have my humidifiers work better. Especially now since my 2 boys are sick. They each have

one in their room even and it’s usually only stays at 20-30%
