The size of the reed diffuser you need depends on the size of the room you want to scent and how long you’d like the fragrance to last. Here’s a general guide to help you choose the right size:

Small (100ml)

• Ideal for: Small rooms (bathrooms, closets, small offices).

• Duration: Typically lasts 1-2 months.

Medium  (150 ml – 200 ml) 

• Ideal for: Smaller to medium-sized rooms (bedrooms, kitchens, or living rooms).

• • Duration: Typically lasts 2-3 months.
  • Scent Strength: Noticeable but not overpowering.

Large (250 ml – 300 ml)

• • Ideal for: Larger rooms (living rooms, open spaces, or larger offices).
  • Duration: Typically lasts 3-4 months or longer.
  • Scent Strength: Strong and noticeable, fills a larger space.

Considerations:

• Room size: Larger spaces require larger diffusers to fill the area with fragrance.
• Scent preference: If you prefer a stronger scent, go for a larger diffuser, or add more reeds for more fragrance diffusion.
• Frequency of flipping reeds: Flipping the reeds more often can refresh the scent and enhance the fragrance’s strength, so you may want a smaller size if you like to control the intensity.
