How does a reed diffuser work?

A diffuser is a bottle of fragrance oil with reeds (or, with Côte Noire, a decorative flower) sitting in it. The oil travels up the reeds and slowly releases scent into the room. The more reeds you use, the stronger the scent.

Our favourite diffusers

Côte Noire's flower diffusers look as good as they smell – a decorative rose or bouquet that draws up the fragrance. Read more in our new Côte Noire roses post.

How to make your diffuser last longer

Keep it out of the sun and away from heaters

Heat and direct sunlight make the oil evaporate faster.

Flip the reeds now and then

When the scent fades, turn the reeds over to refresh it. Don't overdo it – flipping too often uses the oil faster.

Choose the right size for the room

A single rose or bud is perfect for a bathroom, desk or bedside. Use a bouquet or five-rose diffuser for living areas and entryways.

Refill instead of replacing

Côte Noire refills like the Belle Époque refill let you keep your diffuser going for longer.

Reed diffuser FAQs

How long does a reed diffuser last?

It depends on the size, the number of reeds and how warm the room is – most last for several months. Keeping it out of the sun helps it last longer.

Where should I put my diffuser?

Somewhere with a little air flow, like an entryway, bathroom or living room – but away from direct sun, heaters and little hands or pets.

Are diffusers a good gift?

One of the best! They look beautiful, suit almost everyone and last for months. See more ideas in our Christmas gifts for her guide.

Is shipping free?
