I have a closet that I need to get an exhaust setup for asap. Temps are just getting too hot. I want exhaust with a carbon filter into the ceiling. I'll be using 4in filter and fan. However just the flange is 4in, the filters are more like 7-8 around. So any advice on how to get the filter inside the ceiling? If I cut a larger hole, how can o create good duct seal using 4in? It's an older home and currently no attic access.
