Filter Retrofit kit easily replaces “clothes dryer exhaust hood Air Intake”
Clothes dryer exhaust hood air intakes almost never incorporate any kind of filter. But sometimes they have permanently installed window screen that quickly loads up and stops airflow. Cleaning window screen is especially burdensome and needs to be performed every 30-60 days.
