A reed diffuser is one of the easiest home fragrances to make: a bottle, a diffuser base, a fragrance oil and a handful of reeds. There is no flame and no electricity, and a good one scents a room for weeks. This guide covers what you need, the right ratio of base to fragrance oil, how many reeds to use, and how to fix a diffuser that you can't smell.
What you need
- A reed diffuser bottle with a narrow neck. A narrow opening slows evaporation, so the liquid lasts longer. Our reed diffuser bottles come with rattan reeds and a cap.
- Reed diffuser base: a clear liquid made to travel up the reeds and release the scent steadily. It has very little smell of its own.
- Fragrance oil: any of our perfume oils or inspired fragrance oils. Many list reed diffusers under "Works well in" on the product page.
- Rattan reeds: rattan has tiny channels running along its length that draw the liquid upward. Bamboo skewers and wooden sticks look similar but don't wick properly.
- A small scale or measuring jug, and a glass jar or jug for mixing.
What ratio of fragrance oil to base?
Start with 20% fragrance oil to 80% reed diffuser base. For a 100 ml diffuser, that is about 20 g of fragrance oil and 80 g of base.
| Strength | Fragrance oil | Reed diffuser base | Good for |
|---|---|---|---|
| Light | 15% | 85% | Bedrooms, small rooms, bathrooms |
| Standard | 20% | 80% | Most rooms |
| Strong | 25% to 30% | 70% to 75% | Large living rooms, hallways, open-plan spaces |
Going much above 30% rarely makes a diffuser stronger. Thick, heavy fragrance oils can clog the reeds, which makes the scent weaker. Check the IFRA certificate on the product page for each fragrance oil to confirm it is suitable for this use.
How to make it
- Weigh the fragrance oil into your mixing jar.
- Add the reed diffuser base and stir gently for a minute until the mixture is completely clear. If it stays cloudy, the fragrance oil may not suit the base; try a lower percentage.
- Pour it into the bottle using a small funnel. Fill to about two-thirds or three-quarters full.
- Insert the reeds and leave them for an hour so they soak up the liquid.
- Flip the reeds so the wet ends are at the top. The scent will start to fill the room.
How many reeds should I use?
More reeds means more surface for the scent to evaporate from, so the room smells stronger but the liquid runs out faster.
- Small room or a 50 ml bottle: 3 to 5 reeds.
- Average room or a 100 ml bottle: 5 to 8 reeds.
- Large room or a 200 ml bottle and above: 8 to 12 reeds.
If a diffuser is too strong, take a few reeds out. If it is too faint, add a few.
How long does a reed diffuser last?
A 100 ml diffuser usually lasts one to three months. It runs out faster with more reeds, in a warm room, near an air-conditioning vent or in direct sunlight, and in rooms with a lot of air movement. In the UAE, keep diffusers away from AC outlets and sunny windowsills, which can empty a bottle in a few weeks.
My reed diffuser doesn't smell. What's wrong?
- Your nose has got used to it. This is the most common reason. Step out of the room for a while, or ask someone who has just come in.
- The reeds need flipping. Turn them over every few days.
- The reeds are clogged. After a month or two the channels fill with fragrance residue. Replace them with fresh rattan reeds.
- The mix is too weak or too strong. Adjust towards the standard 20% ratio.
- The wrong base. Water and carrier oils don't travel up rattan reeds well, and plain alcohol evaporates too quickly. Use a base made for reed diffusers.
Safety
Keep diffusers out of reach of children and pets, and put them on a mat or tray: the liquid can mark wood, painted surfaces and some plastics. When flipping reeds, hold them over the bottle or the sink and wash your hands afterwards.
