Give it 48 hours to settle in; the scent will build gradually.
Unscrew the fragrance bottle and place bottle into the container (don't pour into the brass vessel).
Fit the lid, add 5–6 reeds to start, and adjust over the next few days to find your preferred strength.
Flip the reeds every couple of days to keep the scent fresh, and place somewhere with good air circulation.

Are your diffusers made in England?
Yes. Every diffuser is hand-assembled and filled in London using our signature fragrances and sustainable materials.
What are your diffuser fragrances made from?
Each fragrance combines essential oils with phthalate-free, paraben-free, and sulphate-free fragrance oils - always responsibly sourced.
How long will my diffuser last?
Each 125ml diffuser lasts around 3–4 months, depending on room size, airflow, and number of reeds used.
Can I reuse my brass vessel?
Absolutely. All of our diffusers are designed to be refilled using The Muses refill bottles. Just replace bottle with a fresh one.
How can I make my diffuser last longer?
Start with 5–6 reeds and add more gradually for stronger scent. Flip the reeds every few days to refresh the fragrance and keep airflow around the diffuser clear.
Are The Muses diffusers sustainable?
Yes, our vessels are made from pure brass designed for long-term use, our packaging is fully recyclable, and our refill bottles are made from recycled materials.

Raw, green energy bottled. Tonic fills the room with that just-cut scent - alive, unfiltered, impossible to ignore. It doesn’t whisper; it hits its stride and stays there.
