How long does a diffuser bottle last?

　　How long does a diffuser bottle last?

The lifespan of a diffuser bottle depends on several factors, including the size of the bottle, the type of diffuser liquid, the size of the reed sticks, and the environment in which it's placed.  

Here are some general guidelines:

1. Bottle Size: The larger the diffuser bottle, the longer it is likely to last.  Diffuser bottles come in various sizes, typically ranging from 100ml to 500ml or more.

2. Liquid Type: The type of diffuser liquid or oil used can affect how quickly it evaporates.  Some formulations are more concentrated and longer-lasting than others.

3. Reed Stick Size: The number and size of the reed sticks you use also play a role.  More sticks and larger sticks tend to release more fragrance, but they may also use up the liquid more quickly.

4. Room Conditions: The environment in which the diffuser is placed matters.  Factors such as room temperature, humidity, and air circulation can impact how quickly the fragrance evaporates.

As a rough estimate, a 100ml to 200ml diffuser bottle can last anywhere from a few weeks to a couple of months, depending on the factors mentioned above.  Larger bottles, such as 500ml, can last several months to a year or more.

It's a good idea to monitor the level of the liquid in the bottle and rotate the reed sticks regularly to refresh the fragrance.  Additionally, you can extend the life of your diffuser by placing it in a cool, dry area away from direct sunlight.
