A room freshener doesn’t have to come in a spray can and you don’t have to plug it into an outlet. You can freshen the scent of your dorm room, living room or even your car with this simple hack.
Tape a dryer sheet to your AC unit, or your car’s AC, and run the unit. No need to cool down the room if you don’t want to–just run the fan. In fact, if you don’t have an air conditioner in your house, this trick works equally well with a box fan.
(Just don’t try this one with a heater.)
