One of our two bathroom renovation projects is just about nearly completed - just a couple of smaller punch list items remain.
One of the things we had replaced was the exhaust fan which was old (I believe from the 1970s), noisy as all heck and inconveniently configured (you had to pull on a draw string to operate it rather than operate it from a wall switch). Thing is, the new exhaust fan has a damper which flips open and closed often when the fan isn't on. I live in a 31-story condo complex and it's not unusual for there to be cross currents that flow through the vent shaft at any given time. If the damper doesn't stay shut when the fan is off, then the dust and other debris that exists in that shaft makes their way into our apartment and things get dusty pretty fast.
I was thinking of buying this car cabin filter and re-purposing it for the fan:

Because the fan wasn't designed to have a filter, I'm concerned that trying to place a filter between the fan itself and the cover will end up burning out the fan motor or something.
Anyone have any feedback about this? Thanks in advance.
