FAQ: How Many Drops of Essential Oil Should You Add to My Diffuser?

It’s one of the most common questions we get — how many drops of Essential Oil should I use in my diffuser? 

Too much can feel overpowering, while too little might not give you that beautiful, lingering aroma you’re looking for.

Here’s a simple guide to help you find the perfect balance:

💧 For an average diffuser (100–120ml): Add 3–5 drops of Pure Essential Oil.
💧 For a larger diffuser (around 300ml): Add 4–6 drops of Essential Oil.

Remember, you can always start with less and add another drop or two until it smells just right for you. 

A few extra tips:

• Let the water diffuse until empty before adding more drops.

• If your diffuser is in a smaller space (like a bedroom or office), use fewer drops.

• Around pets or small children, go gentle — a lighter aroma is best.

• For heavier or stronger Essential Oils such as Patchouli, Ylang Ylang, or Geranium, start with fewer drops, as these Oils have naturally powerful aromas.

Every space and aroma preference is different, so experiment until you discover your ideal balance. Once you find your perfect amount, your diffuser will fill your space with just the right level of calm, freshness, and comfort.

Diffusing Essential Oils is one of the best ways to enjoy all the benefits of Aromatherapy.
