The Best Essential Oils for Diffusers

August 11, 2026

There’s something about walking into a room that smells beautiful.

A few drops of the right essential oil can completely change the feeling of a space. Fresh and uplifting in the morning. Calm and quiet before bed. Grounding after a long day. Or warm and inviting when friends come over.

That’s what we love about diffusers. They’re not just about making your home smell good. Scent can become part of the atmosphere and part of your daily rituals.

But with hundreds of essential oils to choose from, where do you start?

Here are some of our favourite essential oils and blends for diffusing, depending on the mood you want to create.

Lavender for Relaxation and Sleep

If you only have one essential oil for your diffuser, lavender is a pretty good place to start.

Its soft floral aroma is one of the most recognisable scents in aromatherapy and is traditionally used to encourage relaxation and create a calming atmosphere.

Try diffusing lavender in the evening while you’re reading, taking a bath or getting ready for bed.

For an even easier nighttime ritual, our Dream Ritual Aura Mist combines lavender with Roman chamomile and sweet orange in a beautiful pillow and room mist.

Orange for a Fresh, Happy Home

There’s a reason citrus scents make a room feel instantly brighter.

Sweet orange has a warm, juicy and uplifting aroma that works beautifully in a diffuser, particularly during the day.

Try it in the kitchen, living room or workspace when you want your home to feel fresh and welcoming.

It also pairs beautifully with woody oils such as cedarwood and fir.

Cedarwood for Grounding

If citrus is sunshine, cedarwood is the opposite end of the spectrum.

Warm, woody and earthy, cedarwood creates a deeper, more grounded atmosphere. It’s beautiful on its own but particularly good when blended with brighter oils.

Try cedarwood in the evening, during meditation or when you want your home to feel quieter.

It’s also one of the notes that gives our Noël Diffuser Oil its beautiful forest character.

Frankincense for a Quiet Ritual

Frankincense has a warm, resinous aroma that has been used in ritual and incense traditions for centuries.

In a diffuser, it creates a calm, contemplative atmosphere that works beautifully for meditation, yoga or simply slowing down at the end of the day.

Try combining frankincense with citrus or woody oils if you find the aroma too rich on its own.

Ylang Ylang for Something Softer

Sweet, floral and slightly exotic, ylang ylang can completely change the character of a blend.

It has a rich aroma, so you don't need much. Pair it with citrus, cedarwood or frankincense rather than using a large amount on its own.

We particularly love it in an evening diffuser blend when you want something warm and cocooning rather than obviously “sleepy”.

Eucalyptus for a Fresh, Clean Feeling

Eucalyptus has a distinctive fresh, camphoraceous aroma that gives a room an immediate sense of freshness.

It can be lovely in bathrooms, during a morning shower or when you want your home to feel clean and invigorating.

Because it's quite powerful, start with a small amount when blending it with other oils.

Balsam Fir for a Forest Feeling

If you love the smell of a real Christmas tree, balsam fir is one to know.

Fresh, green and distinctly forest-like, it brings that outdoor feeling inside and is beautiful during the cooler months or whenever you want your home to feel like a forest retreat.

Our Noël Diffuser Oil combines balsam fir with cedarwood and juniper berry, then adds orange, cinnamon, clove, nutmeg, vanilla and ylang ylang for a warm Christmas scent.

It's particularly good for making an artificial Christmas tree smell like Christmas.

Or Keep It Simple With a Ready-Made Blend

You don't need to become an aromatherapist to enjoy a beautiful diffuser.

One of the easiest ways to get the balance right is to choose a blend that has already been formulated around a particular mood or atmosphere.

At Daily Rituals, we create botanical blends for exactly this reason. You can simply add the recommended amount to your diffuser and let the scent do the work.

For a relaxing evening, choose a calming blend.

For Christmas, choose Noël Diffuser Oil.

And if you're creating a bedtime ritual rather than diffusing, Dream Ritual Aura Mist gives you a simple way to bring scent into the bedroom without setting up a diffuser.

How Many Drops Should You Put in a Diffuser?

More isn't necessarily better.

Always follow the instructions for your particular diffuser and the dilution guidance provided by the essential oil or blend you're using.

A good starting point is usually a small amount. You can always add more if you want a stronger aroma.

It's also worth remembering that essential oils are highly concentrated. Keep them away from eyes and skin unless they're properly diluted, and take extra care around children and pets.
