mentioned that based on his experience Panasonic makes the best (most

Noise isn't always bad. My NoiseTone fan reminds me to turn it
off. Otherwise I might leave home with the NoiseTone vacuum
pump still running which will create a negative pressure that is
not efficient when it comes to heating or cooling a house.

That's what a timer switch is for.
