Do Longer Fibre Reeds Make a Reed Diffuser Stronger?

A little, because longer fibre reeds have more surface area in the air, so they can release a bit more scent. But the number of fibre reeds, whether they are fresh, and where the reed diffuser sits make a far bigger difference. For picks that fill a whole room with scent, see our guide to the strongest smelling reed diffusers.

What changes strength the most?

Several things change how strong a reed diffuser smells, and the table below ranks them from the biggest effect to the smallest, so you know where to start.

Factor Effect on strength
Number of fibre reeds Big. More fibre reeds, more scent
Fresh vs clogged fibre reeds Big. Clogged fibre reeds barely work
Placement and airflow Big. Gentle airflow spreads scent
Room size Big. Small rooms feel stronger
Flipping Medium. A fresh burst each time
Fibre reed length Small to medium
Reed material Small to medium

As you can see, fibre reed length sits near the bottom of the list, so it is worth checking the bigger factors before you buy a new set of fibre reeds.

What is the trade off with longer fibre reeds?

Longer fibre reeds expose more of the soaked fibre reed to the air, which can boost the scent, especially in bigger rooms with a large bottle. But very long fibre reeds in a small bottle can tip over, and the oil also has further to travel before it reaches the top.

Fibre or rattan?

  • Rattan is a natural material that absorbs the oil well, but it tends to clog sooner than fibre does.
  • Fibre reeds are made to wick the oil evenly from bottom to top, and they tend to last longer before they clog.

Either type works well as long as the fibre reeds are fresh, so choose whichever you prefer the look of.

Can you cut reed diffuser sticks?

Yes, you can cut them if they are too tall for the bottle and keep tipping it over. Cut the end that has not been in the oil, and make sure you do it before you use them for the first time.

Can you wash or reuse fibre reeds?

Not effectively, because the oil soaks right into the fibre reed and cannot be washed out, however hard you try. Replace them with each new bottle, and see how to refill a reed diffuser for the full steps.

How can you get more strength today?

  1. Add more fibre reeds to the bottle, since each one draws up oil and adds scent to the room.
  2. Flip them so the oil soaked ends are at the top and give off a fresh burst of scent.
  3. Move the reed diffuser to waist height, away from draughts and heat, and near a spot where people often walk past.
  4. Replace clogged fibre reeds with a fresh set, because old fibre reeds barely draw up any oil and give off very little scent.

Quick answers

Which reed diffuser sticks are best?

The best ones are fresh fibre reeds that suit the height of your bottle, and fibre reeds tend to wick more evenly than rattan.

Do reed diffusers need new fibre reeds?

Yes, they need a fresh set of fibre reeds with every new bottle or refill, so old, clogged fibre reeds and the last scent do not hold them back.

How long do fibre reeds last?

Fibre reeds last for about one bottle's life before they clog and stop drawing up the oil well, so plan to change them each time.

Matching the scent to the room

Scent choice matters as much as the fibre reeds you use, and bright citrus and herbal blends carry further in bigger, busier rooms. For those spaces, try the Kew Morning reed diffuser. Softer blends like the Belgravia Linen reed diffuser suit smaller rooms such as guest bathrooms, where you want a gentler scent that does not fill the air.
