Diffuser oils are perfect for using with fragrance reeds as the carrier oil, which is the oil that the essential oil or synthetic fragrance oil has been blended with, has been specially formulated to carry the oils through the reed.
This small aroma diffuser includes a central chamber where a small pad is located - a few drops of oil onto the pad gives it whatever scent is desired, and the pads can be washed and reused to create different scents as desired.
If you want to use essential oils, however, you'll have better luck combining 1 ounce essential oil, 2 1/4 ounces pre-formulated reed diffuser oil base or fragrance grade dipropylene glycol, and 1/4 ounce perfumer's alcohol.
Although it may seem like the mixture in a reed diffuser is no different than standard fragrance oil, it is actually a special blend that is designed to help the scent distribute throughout the area.
If you've paid a fair amount of money for a reed diffuser that perfectly coordinates with your home décor, it's only natural that you won't want to simply dispose of it when the fragrance is gone.
