I installed the Vent Axia Svara as recommended by Charlie DIYte. The app seems like a gimmick but it's actually really useful for setting up as the fan has lots of different modes. It's also really easy to clean it out as you can take the fan unit out to access the duct.
But yeah I also use a squeegee and a Karcher window vac, which are far more effective at keeping moisture levels down than the fan.
