The term used to describe the strength of fragrance is called "scent throw." The number of reed sticks will affect the scent throw. Add more reed sticks to increase scent throw.
Flip over the reed sticks occasionally to ensure an even distribution of scent.
Each bottle of reed diffuser will add a graceful scented backdrop to any space for approximately 8 - 12 weeks.
If you find that the scent becomes weak after prolonged usage, your reed sticks may be clogged or it could be that you are used to a certain type of scent. Change your reed sticks regularly and rotate across a few scents over the year to enhance the scent experience.
