Here's that bathroom fan - close up style. It's pretty easy to clean, which is good because after a while, the vents will load up with floating dust that will naturally collect at this point. All you need for cleaning is a damp cloth with swipe over the vents and you're done.
This fan really moves some air too. And it does it whisper quiet. A fan like this makes the bathroom a lot more usable for everyone during the morning rush to get ready for work.
