This is the one I have
4L Cool Mist Humidifiers, 26dB Quiet Ultrasonic Humidifiers for Bedroom Large Room Home, 95mm Water Inlet, Adjustable Mist, Auto Shut-Off, Easy to Clean and 12-50H Humidifying (Grey) https://www.amazon.com/dp/B09J582LWZ/ref=cm_sw_r_cp_api_glt_i_D994MW5RTMW3XQHFP2MB?_encoding=UTF8&psc=1
The one I had is no long on Amazon but this one looks similar, just fill it back up when empty and you are good to go. I have mine set to high all the time. With the size I fill it up once a day.
I don't really use a good dehumidifier so I will be on the market soon as well.
