To make custom essential oil blends for your diffuser, pick the mood you want, choose 2 or 3 oils that fit it, and add 3 to 8 drops total to your diffuser. That's it! Below I show you my simple, beginner-friendly method, with oil ideas for every mood and easy pairs to try. Jump to the steps.
Diffusing essential oils is one of the easiest ways to enjoy aromatherapy. You can transform any indoor space with just a few drops.
Why Diffuse Essential Oils?
Diffusing fills a room with scent, and scent can change how a space feels. People diffuse essential oils to:
- Set a calm, cozy mood at bedtime
- Create a bright, cheerful feel in the morning
- Freshen a stuffy room or cover cooking smells
- Make a work or study space feel fresh and focused
You can use a diffuser anywhere in your home or office. If you're new to diffusers, check out these posts:
What's so beautiful about making your own diffuser blend is that you can match the scent to exactly what you want. Let me show you how.
How to Create Custom Essential Oil Blends
I share lots of diffuser recipes, but I also want you to be able to create your own. I want to take away any fear you may have about mixing essential oils. There is nothing to fear. It's easy, plus you get to play mad scientist :)
Here are the steps to create your own custom diffuser blend.
Step 1: Choose Your Mood
Decide what kind of feeling you want your blend to create. Calming, uplifting, energizing, or cozy? Ask yourself:
- Do you want to relax?
- Are you feeling down and want something cheerful?
- Ready to feel energized?
- Are you studying and want a fresh, focused space?
- Is it close to bedtime?
- Do you want a peaceful, welcoming home?
Step 2: Select Your Oils
Choose oils that fit the mood from step one. For my diffuser, I prefer this mood-first method over blending by notes (top, middle, and base). Yes, I want my blends to smell nice, but I don't pick my oils and drops by note when I'm diffusing.
This method is easier for beginners. I like to choose 2 or 3 essential oils per blend, and I rarely go above 5.
Here are some common oils for each mood. This isn't a complete list. Check the age notes, since some oils are for older kids and adults only.

Step 3: Make Your Custom Blend
Once you've picked your oils, it's time to blend them. The number of drops of each oil changes the scent of the whole blend.
I either mix my oils in a small bottle or drop them right into the diffuser. I like to keep a small notepad or recipe card handy to jot down how many drops I used and how I liked it.
Use 3 to 8 drops total for most diffusers. Some oils are very strong, so start with just 1 or 2 drops of these so they don't take over the blend:
- Ylang ylang
- Patchouli
- Sandalwood
- Rose
- Clove and cinnamon (ages 12+, 1 to 2 drops at most)
Two oils are a great starting point, especially with a smaller collection. Here are some pairs I like to use in my custom essential oil blends:
- Citrus + Woodsy: tangerine and white fir
- Licorice + Citrus: sweet fennel and grapefruit (skip fennel in pregnancy)
- Floral + Spicy: lavender and cardamom (ages 10+)
- Spicy + Citrus: ginger and sweet orange
- Spicy + Floral: clove and lavender (ages 12+)
- Resin + Woodsy: frankincense and black spruce
- Clearing + Zesty: eucalyptus and lime (ages 10+)
Step 4: Enjoy!
Add your oils to the diffuser with the amount of water your diffuser calls for. Once it's running, notice whether the scent matches the mood you wanted, and jot down any changes for next time.

A Few Diffusing Safety Basics
• Don't diffuse around babies under 2, including in a room they sleep in.
• Diffuse for 30 to 60 minutes at a time, then take a break, and keep the room aired out.
• Leave a door open so pets can leave the room. Cats are especially sensitive to citrus and tea tree oils.
• Check the age for each oil. Peppermint is for ages 6 and up; rosemary, eucalyptus, and cardamom for 10 and up; and clary sage, clove, and cinnamon for 12 and up.
• If you're pregnant, check with your doctor or midwife first. For the first 16 weeks I diffuse only six oils: lavender, sweet orange, lemon, ginger, cedarwood (Virginian), and frankincense.
• If a scent makes anyone sneeze, wheeze, or feel unwell, turn the diffuser off and open a window.
