The two most important points are: not to use too much essential oil and to use quality essential oils. These oils are generally very concentrated. We must, therefore, be very careful. A small amount of essential oil can thus release a large amount of fragrance as well as a large dose of active ingredients, which could be harmful to people and animals.
How many Drops of Essential Oil to Put in Its Diffuser?
Keep in mind that less is always more when it comes to aromatherapy—extracted from plants, all essential oils tend to be highly concentrated, with a relatively strong aroma. We strongly recommend that beginners start with a small amount and work their way up.
Here’s How many Drops of Essential Oil to Put in Your Diffuser
Diffuser size Number of drops
- 100mL 3-5
- 200mL 6-9
- 300mL 10-12
- 400mL 12-15
- 500mL 15-18
The Case of the Ultrasonic Diffuser
The formula is easy to use. We suggest that you put four drops of essential oil for 100 milliliters of water. For example, if your diffuser has a capacity of 300 ml, you will need to add 12 drops of essential oil.
Be careful not to put too many drops of essential oil.
The usual amount of water in a small diffuser is 100 ml. In this case, it is generally recommended to add 3 to 5 drops of essential oil per 100 ml of water. The rule above gives us exactly four drops. Of course, the amount you choose to add will vary depending on your personal preferences, as well as the size of the room – larger rooms will benefit from a bit more oil.
Diffusers come in different sizes, but these are usually in 100ml increments, so calculating how many drops of essential oil to add is relatively easy. Smaller 100ml diffusers take an average of 3-5 drops, while larger 500ml diffusers take 15-20 drops.
The Number of Drops for the Essential Oil Nebulizer
Unlike the ultrasonic diffuser, the nebulizer uses essences exclusively. Which, volatile, will be propelled into the air by fine pure droplets.
The process is very efficient, so it should not be overused. For a small room of 10-20 square meters, we recommend 3 to 5 drops. Up to 12-15 drops for a large room of 50 square meters and more.
Obviously, you can make a mixture of different essential oils. But as much as possible, try to stick to these recommendations for the total number of drops in your recipe.
How to Convert the Number of Drops to ML?
There are about 200 drops in a 10ml bottle of essential oil. This means that you can get about 50 uses from a 10ml bottle of essential oil if you use a 100ml diffuser.
You can usually buy essential oils in small 5-15ml bottles. However, some types are available in larger bottles up to 100ml.
Signs you’ve Used too Much Essential Oil
If you experience any of these symptoms, it means that you may have put on too much essential oil. Being heavy-handed with the amount of essential oil you put in your diffuser isn’t usually very good. Watch out for side effects.
If you have any of the following effects, we advise you to dilute the essential oils by two in more water: dizziness, migraines, nausea, or vomiting.
If this is your first time using essential oils or pairing them with an essential oil diffuser, then if in doubt, cut down. Start with fewer drops first, then adjust the amount afterward to suit your room size and personal taste.
