Diffuser refill oils
How to refill a reed diffuser so it smells as good in week six as it does on day one
How to refillUsage guide
Four steps, and the reasons behind them.
-
1
Let it run dry first
Wait until the old oil is almost gone. Pouring a new scent onto the remains of an old one muddies both, and you will not get a clean read on either.
💡 Tip: a bottle is 'empty enough' when the reeds no longer sit in liquid.
-
2
Fill to about two thirds
Unscrew the safety cap and pour. Leave room at the neck — reeds displace oil, and a bottle filled to the top simply overflows when they go in.
💡 Tip: refill over a sink or tray. The oil marks polished and painted surfaces.
-
3
Use fresh reeds
Old reeds clog with evaporated oil and gradually stop drawing, which is the usual reason a refill seems weaker than the original. Start each bottle with new ones.
💡 Tip: 3–8 reeds. Fewer for a subtle scent, more for a bigger room.

4
Flip weekly, replace every 6–8 weeks
Turn the reeds over once a week to refresh the throw. A full bottle lasts six to eight weeks in an average room.
💡 Tip: stand the bottle away from radiators and draughts — heat and airflow burn through it faster.
150ml per bottle
Enough to fill a standard 100ml diffuser and top it up again later.
Six to eight weeks
From a full bottle in an average room. Warm, draughty or open-plan rooms get through it faster.
Fits any reed diffuser
Ours or anyone else's. Not for electric or ultrasonic diffusers — the oil is not water-soluble.
💡 Reeds and a bottle only.
Frequently asked questions
Will it fit my diffuser?
Yes — it works in any reed diffuser bottle, ours or anyone else's. A 150ml bottle fills a standard 100ml diffuser with enough left over to top it up later.
Can I use it in an electric or ultrasonic diffuser?
No. This is a reed diffuser oil and is not water-soluble, so it will clog an ultrasonic diffuser and may damage it. Reeds and a bottle only.
How long does a bottle last?
Six to eight weeks from a full diffuser in an average-sized room. A warm, draughty or open-plan room gets through it faster, and more reeds means more scent but a shorter life.
Do I need new reeds every time?
We would recommend it. Reeds clog with evaporated oil over time and gradually stop drawing, which is usually why a refill seems weaker than the original. Fresh reeds bring it back to full strength.
Can I mix two scents?
Better not to. Pouring a new scent onto the remains of an old one muddies both. Let the bottle run almost dry first, and start the new scent with new reeds.
Why can I not smell it any more?
Usually one of two things. Noses adapt to a constant smell within a few days — visitors will still notice it. Or the reeds have clogged, in which case flip them, or add a couple more.
What is actually in it?
High-quality fragrance oil on a clean, low-odour carrier chosen to evaporate slowly. No water, no alcohol burn-off, and nothing that smells of solvent underneath the fragrance.
Ready for a refill?
150ml of fragrance oil on a clean, slow-evaporating base, in a choice of scents.
