### ⭐⭐⭐⭐ Passive air vent, can be opened and closed from the inside
*by S***I on September 10, 2024*

Modern houses don't breathe very well. This is a way to control where fresh air enters into your home. Negative pressure is created within the home by the various exhaust systems (cooking, bathroom, whole house and so on). This unit has everything you need to allow it in. The plastic plunger has 4 settings: Closed (has a rubber seal on the inside), low, med, high. You press to change the setting. Contains a mesh filter, though it isn't clear how that would be cleaned or replaced. What it does not contain is a damper of some sort that would automatically close or open as needed, though something like this can be purchased for in-line duct use. A convenient quick-install kit for the right situation.
