A reed diffuser is one of the easiest ways to fragrance your home beautifully, day after day—no flame, no fuss. The key is choosing the right diffuser for your room size, the scent strength you like, and the longevity you expect.
This guide walks you through exactly what to look for, plus simple care tips to keep your diffuser performing at its best.
How to choose a reed diffuser for your room size
Room size is the fastest way to get the right result. If the diffuser is too small for the space, the scent can feel faint. Too large, and it may feel overpowering.
· Small rooms (cloakroom, bedside table, compact home office): choose a smaller diffuser and start with fewer reeds for a softer scent.
· Medium rooms (bedroom, snug, hallway): a standard diffuser is usually ideal for balanced, everyday fragrance.
· Large rooms / open-plan spaces (kitchen-diner, large living room): choose a larger size or use two diffusers placed at different points in the room for even scent coverage.
Tip: High ceilings, open windows, extractor fans, and busy hallways increase airflow, which can reduce how strongly you notice the fragrance.
How long does a reed diffuser last?
How long a reed diffuser lasts depends on: - Oil volume (more oil usually lasts longer) - Number of reeds (more reeds diffuse faster) - Temperature and sunlight (heat speeds evaporation) - Air movement (drafts increase diffusion)
To improve longevity: - Keep your diffuser away from radiators and direct sunlight. - Avoid placing it right next to open windows or strong drafts. - Use only as many reeds as you need for the room.
If you like to change fragrances seasonally, a standard size can be perfect. If you want a true set-and-forget fragrance, choose a larger size or a calmer placement spot.
How to choose the right scent strength (and fragrance family)
Scent strength isn't only about intensity; it's also about how a fragrance behaves in a space.
A simple way to choose: - Fresh / citrus / herbal: bright and uplifting; ideal for kitchens, hallways, and mornings. - Floral / soft musks: elegant and calming; perfect for bedrooms and dressing areas. - Woods / amber / oud / spice: richer and more enveloping; best for living rooms and evenings.
If you're fragrance-sensitive, start with fewer reeds and flip them less often. You can always increase the scent throw gradually.
Where to place a reed diffuser for best results
Placement makes a bigger difference than most people expect.
For best performance: - Place your diffuser where air naturally moves, but not where it blasts; near a doorway or on a console table works well. - Keep it out of direct sunlight to help preserve the fragrance. - Choose a stable surface away from pets and little hands.
Great placement ideas by room: - Hallway: console table for an instant welcome. - Bathroom: shelf away from direct heat and steam. - Bedroom: dresser or bedside area, using fewer reeds for a softer finish. - Living room: sideboard or bookshelf at mid-height for even diffusion.
How often should you flip diffuser reeds?
Flipping reeds refreshes the scent throw quickly—perfect before guests arrive or when you want a lift.
· For a steady everyday scent: flip reeds once a week (or every 10-14 days).
· For a lighter scent: flip less often, or reduce the number of reeds.
· For a stronger scent: flip more often, or add an extra reed or two.
How to flip without mess: 1. Wash and dry your hands. 2. Turn reeds over one at a time. 3. Wipe any drips from the bottle.
Note: More frequent flipping increases scent strength but can reduce longevity.
Reed diffuser care tips (to keep it clean and consistent)
· Don't top up with water.
· Replace reeds if they become dusty or saturated over time.
· Keep the bottleneck clean to avoid residue buildup.
· If switching scents, start with new reeds to avoid mixing fragrance profiles.

FAQ
How many reeds should I use?
Start with fewer reeds in small rooms and add more if you want a stronger scent. More reeds increase scent throw but can reduce longevity.
Why can't I smell my diffuser anymore?
You may have become scent-adapted, or the reeds may be saturated/dusty. Try flipping the reeds, moving the diffuser to a slightly higher airflow spot, or replacing the reeds.
Can I put my diffuser on a windowsill?
Its best to avoid direct sunlight and heat, which can speed evaporation and shorten how long the diffuser lasts.
