Well, our apartment was also street level so the sound of cars and such driving by in the morning could have woken us up just as much as this. Plus, I'm a heavy sleeper so I slept through it, but not my fiancée, but we also got up for work around then anyways it didn't bother me. Plus weekend quiet hours were later.

It runs when it's full, so for a large amount of time we were at the apartment (like 6 -8 months in since it was peak pandemic) , it was only running at night sporadically, so much less noticeable, and by the end when it did start to be more noticeable, we just picked our battles since we intended to move apartment anyways (was just waiting for the one we wanted to open up).
