I have a bedroom closet booth in progress. I have drilled a hole for an intake plenum at the bottom of the booth and will add another one on top for exhaust with a bathroom fan sucking out the air. The closet is very small - 42" by 69". The hole goes through to a bedroom closet on the other side where I basically have all my clothes.
I have built this plenum out of mdf. But I wonder what I should put inside. I have lots of extra carpet padding and auralex foam.
Here's a couple photos. As you can see, I have an old house with horse hair plaster and wood lathe...
