Best Occasions To Give A Reed Diffuser Gift Set
Is it worth buying a diffuser refill?
THE QUICK ANSWER
A 200 ml reed diffuser refill typically provides around four to eight months of fragrance, depending on how many reeds you use, the room temperature, airflow and where your diffuser is placed. Because our refills contain twice as much fragrance oil as a standard 100 ml diffuser, they're designed to keep your home beautifully fragranced for even longer.

Frequently asked questions
Once you've fallen in love with a reed diffuser, refilling it is one of the simplest ways to keep enjoying your favourite fragrance.
But how long should a refill actually last?
The answer depends on a few different factors, including how many reeds you use, the environment your diffuser sits in and how often you turn the reeds. In this guide, we'll explain what affects longevity and how to get the very best value from your diffuser refill.
1.How Long Should A Diffuser Refill Last?
Our 200 ml diffuser refill is designed to fragrance your home for approximately four to eight months under typical home conditions.
Every home is different, so the exact lifespan will depend on:
-
Number of reeds used
-
Room temperature
-
Airflow
-
Direct sunlight
-
Room size
Used in a cool, well-positioned room with the correct number of reeds, many customers enjoy beautiful fragrance for several months.

EPSILON TIP
Always replace your reeds when refilling your diffuser. Fresh reeds absorb fragrance more efficiently and help restore your diffuser's performance.
2.Why Our Refills Last Longer
Unlike many standard diffusers, our refill bottles contain 200 ml of fragrance oil.
That's twice the amount of oil found in our 100 ml reed diffusers, giving you significantly longer enjoyment before needing another refill.
Every refill also includes:
✓ 200 ml premium fragrance oil
✓ 16 premium black fibre reeds
That's double the fragrance oil and double the reeds supplied with our standard diffuser, making it easy to refresh your diffuser properly every time you refill.
3. What Affect's How Long A Refill Lasts
Several factors influence how quickly fragrance oil evaporates.
Number of Reeds
More reeds create a stronger fragrance but use oil more quickly.
Temperature
Warm rooms naturally increase evaporation.
Airflow
Open windows, fans and busy hallways can speed up fragrance release.
Position
Keeping your diffuser away from radiators and direct sunlight helps maximise longevity.
4. How To Make Your Refill Last Longer
Getting the most from your refill is simple.
✓ Use fewer reeds in smaller rooms.
✓ Keep away from heat sources.
✓ Avoid placing beside open windows.
✓ Turn reeds only when the fragrance begins to fade rather than every day.
Small changes can significantly extend the life of your refill.
