Create a homemade room spray by mixing 10-20 drops of essential oils in a spray bottle with water. Shake thoroughly every time before using, and spritz around the room to enjoy the scent. It means you don’t have to concern yourself with electricity or heating and can just use the spray as and when you please. One downside is that a water-based spray is less potent than some of the other methods, so it may require more work and for you to lower your expectations a little. Try to never spray this directly onto fabrics as this mixture is likely to stain.
