Not all essential oils are created equally. Many, especially lower cost ones, feature a laundry list of ingredients — you could call them fillers — that are added in to reduce manufacturing costs. While they’re cheaper, sure, you need more to get the same effect. In other words, you’re getting less diffuse time for your money.
The oils on this list do not harbor fillers. These small but mighty concentrated bottles of oil require only a few drops in a diffuser to create a huge impact. Use drops sparingly and a single bottle can easily stretch over a couple months.
