For a couple of years in a house I had in a cold climate. It worked ok, as I had it venting into the basement area. There was a three way valve that allowed the air to be selected to go outside or to the basement. Suprisingly little lint accumulated, however, what worked best to trap any lint was one leg of an old pair of panty hose.
I finally reconnected the vent to the outside as it got too humid in the basement area during wash days.
