The most important thing is not to use too much of any essential oil. These oils are typically highly concentrated, meaning that a small amount of essential oil can release a significant amount of fragrance.

You don’t want to overwhelm the area with fragrance. Any scented product, including essential oils, can be an irritate if it is inhaled. You are aiming for a slight hint of scent, rather than a dousing.

Diffusers do come in different sizes, 100ml to 500ml.  The usual amount of water held by a diffuser is in 100ml increments, and typically it is recommended to add 3-5 drops of essential oil per 100ml of water.  Of course, the amount you choose to add will vary according to personal preference, as well as the size of the room – larger rooms will benefit from slightly more oil.
