About the Fresh 80 Inlet Vent
If you want to introduce outside air into a tight house, use this passive vent to bring outside air in. Use the template provided to cut a circular opening high up on the wall of any room with an exterior wall. The Fresh 80 is a complete unit that telescopes up to 8″ to fit different wall thicknesses. It opens and closes with the pull of a string, although generally it is kept in the open position. The unit contains a washable filter so that allergens, leaves, etc can’t enter the home.
