Diptyque Scented Ovals
These hang beautifully in any closet and diffuse its perfume for about 3 months. It’s a ceramic circle with a scented center (like soap). Also great in the bathroom, basement or your car.
The Laundress Scented Drawer Sheets
These large sheets are great in a drawer, taped to the side or back of a closet, or the inside top of a trunk (as in a large storage box, though it may work in your car too). Toss one in your empty luggage to keep it fresh between trips. The best part is they’re made in the USA.
Carta D’Armenia Burning Papers
These tiny papers burn like incense to remove odors (staleness, dampness, cooking odors) but they’re also good simply tossed in a drawer or cabinet. They’ve literally been around for hundreds of years so you know they work.
