Reed Diffuser Refills

Don't throw away your bottle when the oil runs out. Our reed diffuser refills let you top up your favourite diffuser for a fraction of the cost of a new one. Each 100ml reed diffuser refill (£11.00) or 200ml reed diffuser refill (£19.99) is a ready-to-pour diffuser refill: simply top up your existing bottle, add fresh reeds and let the fragrance gently fill the room.

How to choose the best diffuser refill

The best diffuser refill is the one that suits your room, your bottle and how quickly you get through oil. Here's what to look for:

  • Size: choose the 100ml refill to top up one bottle or try a new scent. Choose the 200ml refill if you already have a favourite: it holds enough to refill one of our 100ml reed diffusers twice, and costs less than two 100ml refills.
  • Scent: pick a fragrance that suits the room. Fresh and clean scents work well in bathrooms and hallways, fruity and floral scents brighten a kitchen or living room, and woody scents feel cosy in the evening.
  • Made for reeds: use a proper reed diffuser oil refill, not perfume, essential oil or water. Diffuser oil is made to travel up the reeds and give a steady scent.
  • Fresh reeds: our refills are oil only, with no reeds or bottle included, so add a new set of reeds each time you refill for the best scent throw.
  • Value: a 100ml refill costs £11.00, compared with £19.99 for a new 100ml reed diffuser, so refilling the bottle you already have saves money and glass.

Diffuser refill oil in your favourite scents

Our diffuser refills come in the same fruity, floral, fresh and woody fragrances as our reed diffusers, so it's easy to keep your favourite going or try something new. See every fragrance on our current scent list. Each reed diffuser oil refill is made for reeds, giving a steady, flame-free home fragrance with no heat and nothing to switch on.

How long does a reed diffuser refill last?

A 100ml refill lasts 8 to 12 weeks, often longer, depending on the room and how often you flip the reeds. The 200ml refill holds twice as much, so it's ideal for topping up more than once or keeping a busy hallway or living room smelling lovely for longer. For a long lasting scent, keep your diffuser away from direct sunlight, heat and draughts, and flip the reeds every few days. Read more in how long do reed diffusers last?, and our step-by-step refill guide shows you how to top up your bottle.

Refills, reeds and bottles

For a fresh scent throw, change your reeds every time you refill: our black reed diffuser sticks come in a pack of seven for £2.50. Fancy a new look? Pour your reed diffuser oil into a decorative reed diffuser bottle, or build your own reed diffuser with your choice of fragrance and colour. New to reed diffusers?

Why Buy A Reed Diffuser Refill?

  • Save money — refills cost significantly less than buying a whole new diffuser
  • Reduce waste — keep your bottle and reeds out of the bin
  • Same premium fragrance oil as our original diffusers — no compromise on quality
  • Easy to use — just pour into your existing bottle and you're done
  • Switch scents whenever you like — mix and match across our full fragrance range

Our Reed Diffuser Refill Range

We offer diffuser refill oils in a wide range of sizes and scents to suit every diffuser bottle:

  • Lavender reed diffuser refill — our best-selling refill, endlessly calming and versatile
  • Vanilla reed diffuser refill — warm, sweet and universally loved
  • Lime, Basil and Mandarin and ginger diffuser refill — zesty and fresh, ideal for kitchens and offices
  • Christmas Spice diffuser refill — festive seasonal scents available all year

Which Refill Size Do I Need?

Our diffuser oil refills are available in several sizes to suit different bottle volumes and usage habits:

  • 100ml refill — suits most standard diffuser bottles and typically lasts 6 to 8 weeks
  • 200ml refill — great for larger bottles or if you want enough oil for two top-ups before changing the reeds

Not sure how much you need? As a rule of thumb, fill the bottle to around two thirds full. This gives the reeds enough oil to wick while leaving room so the oil doesn't overflow when you insert the reeds.

Do I Need To Replace The Reeds Too?

Over time, reed diffuser sticks become saturated and clogged — at this point, flipping them no longer refreshes the scent. We recommend replacing the reeds every one to two refill cycles. We sell replacement diffuser reeds and spare reeds for diffusers separately so you can stock up alongside your refill oil.

How To Refill A Reed Diffuser — Step By Step

  1. Remove the old reeds from the bottle and set aside (or discard if they're past their best)
  2. If switching to a new scent, rinse the bottle with warm water and leave to dry completely before refilling
  3. Pour your reed diffuser refill oil carefully into the bottle — fill to around two thirds full
  4. Re-insert your reeds (or add a fresh set of replacement diffuser reeds) and allow 24 hours for the scent to develop
  5. Flip the reeds after the first 24 hours to kick-start the scent throw

Reed Diffuser Refills FAQ's

Can I use any diffuser refill oil in my bottle?

Yes — our refill oils work in any standard reed diffuser bottle. They are formulated to work with natural rattan reeds for the best scent throw and longevity.

What oil do you use in your reed diffuser refills?

We use the same high-quality fragrance oil blend as in our original diffusers. Our diffuser oil refills use a reed diffuser base oil that is specifically designed to wick well through natural reeds — no synthetic fillers or alcohol-heavy carriers that dilute the fragrance.

How long does a reed diffuser refill last?

A 100ml refill typically lasts 6 to 8 weeks. A 200ml refill can last 3 to 4 months. Longevity depends on the number of reeds, room temperature, and airflow.

My diffuser has stopped smelling — do I need a refill or new reeds?

Check the oil level first. If there is still oil in the bottle but no scent, the reeds are likely saturated — replace the reeds and the scent should return straight away. If the bottle is empty or nearly empty, it is time for a diffuser oil refill.

What is the best reed diffuser refill?

The best reed diffuser refill is one made with high-quality fragrance oil rather than a diluted or alcohol-heavy base. Look for refills that specify the oil concentration and that are designed for use with natural reeds. Our refill oils are made to the same standard as our full diffusers.

Do you offer refills for diffusers from other brands?

Our refill oils are universal and work in any reed diffuser bottle regardless of brand. If you're looking for a scent that matches a diffuser you already own, browse our fragrance range to find your closest match.
