Can the ultrasonic salinizer be compared with a humidifier / humidifying rate?
Absolutely no! The main role of the ultrasonic salinizer is to place breathable micro particles of salt into the indoor air, for long time inhalation by normal breathing. The quantity of humidity that is placed into the indoor air is insignificant and you should expect the saline solution tank to fully empty in 8-9 nights of continuos use.
