I greatly prefer TOP FILL ultrasonic humidifiers because they are so convenient. Just remove the lid, and pour RO water in.
Tap water will produce white dust from the impurities in the water, which will shorten humidifier lifetime, and possibly settle onto plant leaves.
This is a good one

That would take more dialing in the other one has a humidity censor and turns on and off :)
