So, my solution? A paper towel drizzled with essential oils on the back of the fan. The negative air pressure holds the towel against the fan and the air coming out of the fan smells so good! I am sitting in a room infused with lavender and rosemary at the moment. I am so happy to have found a way to make my home smell good without yucky air fresheners and sprays.
**Update** Chris just walked in and said it was way to overpowering.... Note to self, less essential oil next time.
