HEARTLAND 21000 Dryer Vent Closure - Amazon.com
I installed this over the weekend. I had to use calking and I used Tap-Cons I had left over from the mini split install. This is a great item it lets no air in from the outside. This was a major improvement.

I did read in the instructions it can be used for bathroom vent they have a spring kit for low flow applications.
