I changed the fans in both bathrooms to this higher CFM fan. Let’s just say they don’t get left on all frikkin day. I swear the one in the master bathroom would run 24-7. Why?? I have no clue. But now this fan is a little louder and lets you know it is running. Lol.
Hopefully those fart fans are as easy to changes as this one. My house was build in ‘08 I believe...
I took a look, and it seems like the same system behind the grate.
