It depends a bit on what you want to optimize for, as there’s drawbacks to all the major methods:
- Ultrasonic sprayers are decently efficient but spread any contaminants around your home, potentially still biologically active. Dissolved trace minerals will turn into fine dust, affecting cleaning needs.
- Boiling for humidification is energy intensive because of water’s heat capacity.
- Air forced wicks are by default great habitat for mold and similar, so they need regular care and replacement.
I think this is partly about giving yourself an out for liking childish things as a near- or young-adult. Kids shows commonly do include some Parental Bonus but extending that idea specifically to dark undercurrent plots that you have to read between the lines of the text seems like a way to feel “in the know” about something adult in the work while still consuming something you feel society expects you to have grown out of.
Then with a bit more maturing than that, you can hopefully just embrace childish joys earnestly, because joys are precious.
