How Many Drops of Essential Oils Should I Put in My Diffuser?

Diffuser Size Number of Drops
100ml 3-5
200ml 6-10
300ml 9-12
400ml 12-15
500ml 15-20

If it is your first time using a diffuser and you’re not sure how much essential oil to put in, remember that the rule of thumb is to add sparingly in the beginning. It’s easier to add more drops slowly than be overwhelmed at the outset. 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 irritant if it is inhaled. You are aiming for a slight hint of scent, rather than a dousing.

The usual amount of water held by a diffuser is 100ml, 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.

Diffusers do come in different sizes, but these are usually in 100ml increments, and therefore calculating the number of drops of essential oil to add is relatively easy. The smallest, 100ml diffusers will take 3-5 drops on average, while the largest, 500ml diffusers will require 15-20 drops.

Once you’ve used your diffuser several times and experimented with different types of essential oils, you will have a good grasp of how many drops you need to make your room smell exactly the way you want.

Signs That You’ve Used Too Much Essential Oil

If you feel any of these symptoms, this means that you might be heavy handed with how much essential oil you’re putting into your diffuser.

If it’s your first time using essential oils or pairing them with a home diffuser, the rule “less is more” should guide you. Start with less drops first and then adjust the amount later on to suit the size of your room and your individual taste.

It is generally recommended to place a diffuser on a high shelf, in order to allow for maximum dispersal.

All diffuser models vary, but, in general, they are relatively simple to set up.

How Many Drops Are In 10ml?

There are 200 drops in a 10ml bottle of essential oil. This means you can get an approximate 40-65 uses out of a 10ml bottle of essential oil if you’re using a 100ml diffuser.

You can typically purchase essential oils in small bottles that come in 5-15ml bottles. However, some types come in bigger bottles ranging from 30ml (1 ounce) to 120ml. Here are the number of essential oil drops there are in each bottle and how many uses you can get out of your purchase.

Essential Oils – What Are They Used For?

Essential oils are often used to aid in sleep, relaxation, or even rejuvenation usually in a diffuser, as not all oils are suitable to be used on the skin.

Diffusers work by warming up the oils, often using hot water, causing a delicate, subtle fragrance to spread around the room.

Different scents are held to promote different states of mind – for example, lavender and sandalwood are relaxing and can induce sleep, whilst citrus scents are energizing and stimulating.

How Many Drops of Essential Oils to Add to Lotions

Essential oils can make a great addition to fragrance-free lotions, and can add an extra touch to your pampering regime.

When blending essential oils with lotion, the recommended ratio is 3 drops of oil to 10ml of lotion, although, again, this can be varied for personal preference.

This is also a good ratio to work with when blending essential oils with carrier oils such as grapeseed and jojoba for massage.
