How long will a reed diffuser last?

So, you've decided to invest in a reed diffuser to jazz up your home, but now you're wondering how long it'll last. Fear not, my fragrance-loving friend, as I'm here to break it down for you.

First things first, the lifespan of a reed diffuser depends on a few factors. We're talking about the quality of the diffuser, the size of the container, and the environment it's in. Basically, there's no one-size-fits-all answer here.

Now, let's talk about size. Reed diffusers come in all sorts of shapes and sizes, from teeny-tiny 30ml bottles to massive 500ml bottles. Generally, the bigger the bottle, the longer the scent will last. But don't forget that other factors, like the type of fragrance oil used, can also impact how long your diffuser will keep your room smelling sweet.

1-2 weeks



1-2 months



2-4 months



4-5 months



6-12 months


Also don't forget about the environment. If you shove your diffuser in a cramped corner with no ventilation, it's going to evaporate faster than you can say "aromatherapy". Similarly, if you leave it basking in the sun or near a radiator, it's going to dry out quicker than a raisin in the Sahara.

Can the fragrance have an impact on how long the reed diffuser will last?

Yes, the fragrance can have an impact on how long a reed diffuser will last. This is because different fragrances have different evaporation rates, which can affect how quickly the oil is dispersed into the air. For example, citrus or floral scents tend to have a higher evaporation rate than woody or musky scents, meaning they may not last as long.

Additionally, the quality of the fragrance oil used in the reed diffuser can also affect how long it lasts. Higher quality oils tend to last longer than cheaper alternatives.

Why can't I smell my reed diffuser?

There could be a few reasons why you can't smell your reed diffuser. One possibility is that the oil is low quality or has evaporated too quickly. Another possibility is that the environment it's in is too large for the diffuser to effectively fill the room with scent.

How long does it take for reed diffusers to work?

Reed diffusers typically start working within a few hours of being opened. However, it can take up to 24 hours for the scent to fully develop and spread throughout the room.

Still can't smell the reed diffuser in your room?

Let's take a deeper look into why you may not be able to smell your home diffuser, this could be one of a few issues. One of the biggest issues we see is people buying the wrong size diffuser for the size of room you want to infuse with scent.

What Reed Diffuser will I need for the size of the room?

Well, it depends on the size of the room you want to freshen up. For small rooms, a 30-50ml reed diffuser should do the trick. If you're looking to add a lovely scent to a medium-sized room, you might want to consider a 100-150ml diffuser. And for larger rooms, you'll probably want to go for a 200-500ml diffuser to cover the space effectively. Here is a handy table to help you decide:

Reed Diffuser Size

Room Coverage

Example of Room Size

30 - 50ml

Small rooms 

(10-15 square metres)

100ml - 150ml

Medium rooms

(20-25 square metres)

200ml - 500ml

Large rooms

(30-40 square metres)

Other things to consider when it comes to the size of room is the scent throw, this can be adjusted with the size and quantity of reed diffuser sticks used vs the bottle size of reed diffuser.

Top Tips to get the best out of your Reed Diffuser

If you're like me, you want to make that sweet smell last as long as possible. Lucky for you, I've got some tips to extend the life of your reed diffuser and get the most bang for your buck.

Rotate those reeds! 

Give them a spin every few days to prevent dust and debris from clogging them up, and to make sure the scent spreads evenly.

How often should I flip the reed diffuser sticks?

To keep your reed diffuser smelling strong, you should flip the reeds every 1-2 weeks. This helps to redistribute the oil and keep the scent fresh.

Adjust the number of sticks.

If the scent is too strong, take out a few reeds; if it's too weak, add some more. It's like Goldilocks and the Three Bears, but with fragrance. Just don't go overboard, or you might end up with a scent that's overpowering.

How often to change reed diffuser sticks

You should change your reed diffuser sticks every time you switch out the oil. This helps to ensure that the scent remains fresh and strong.

Reed diffuser evaporating too fast

If your reed diffuser is evaporating too fast, try moving it to a cooler location. You could also try using fewer reeds to slow down the evaporation process.

Store it properly. When you're not using your diffuser, Cap that bad boy and put it in a cool, dry spot away from direct sunlight. And hey, while you're at it, give the bottle and reeds a little cleaning every now and then. A damp cloth for the bottle and a rinse in warm water for the reeds should do the trick.

How long do reed diffusers last unopened?

Reed diffusers can last for a few years if they are unopened and stored in a cool, dry place. However, the longer you leave them unopened, the less effective they will be when you finally do use them.

Hopefully with these tips, you can keep that diffuser smelling fresh and keep the good vibes flowing.

Eventually, though, your diffuser might start showing signs that it's time to say goodbye. If you can't smell the scent anymore, even after rotating and adjusting, it's probably time to refill or replace.

What are the Signs that my Reed Diffuser needs replacing?

Wondering if it’s time to replace your reed diffuser? Here are some signs to look out for:

  • Lack of scent: If your reed diffuser has been losing its potency over time and you can no longer smell the fragrance, it may be time to replace or refill it. Even rotating the reeds and adjusting the number of sticks won't work if the fragrance oil has evaporated completely.
  • Discoloration or cloudiness: If the liquid in your reed diffuser has become cloudy or discoloured, it may be a sign that the oil has degraded or become contaminated. Replacing or cleaning and refilling the diffuser with a new one is the best option in this case.
  • Clogged reeds: If you find that the reeds in your diffuser have become clogged with dust or debris, even after rotating them regularly, it may be a sign that it’s time to replace the reed diffuser sticks with fresh ones.
  • Weak scent: If the scent of your diffuser is too weak, try adding more reed sticks to the bottle or placing the diffuser in a smaller, enclosed space.
  • Strong scent: If the scent of your diffuser is too strong, try reducing the number of reed sticks or placing the diffuser in a larger, more open space.
  • Evaporation: If the liquid in your diffuser evaporates too quickly, try storing it in a cooler, less humid area and replacing the cap tightly when not in use.

These signs indicate that it may be time to replace your reed diffuser. Keeping an eye out for them will ensure that you always have a fresh and effective fragrance in your home.

Why does my reed diffuser run out so fast?

If your reed diffuser is running out quickly, it could be due to a few things. One possibility is that the environment it's in is too warm, causing the oil to evaporate quickly. Another possibility is that the diffuser is low quality and isn't designed to last very long.

If you're still having some issues with your diffuser, don't worry. Maybe it needs more reeds or a different spot in your home. Or maybe it's just too darn hot where you live. Whatever the case, keep an eye out for these common issues and know when it's time to let go.


So, there you have it! Reed diffusers can last anywhere from a few weeks to several months, depending on the size, quality, and environment. Remember to flip the reeds every 1-2 weeks to keep the scent fresh, and if your diffuser is evaporating too quickly, try moving it to a cooler location. And if all else fails, you can always try lighting a candle or spraying some air freshener. Happy scenting!

What can I use instead of a reed diffuser?

Not convinced a reed diffuser is for you? Then, why not try using Wax Melts or a scented candle? Both of these options can provide a similar fragrance experience to a reed diffuser and can give an instant aroma to any room.
