# Number of diffusers

Have you ever wondered how many diffusers you need for your room? Maybe youâ€™re not sure how to calculate the size of your room. Either way, this article is for you.

First, letâ€™s calculate the size of your room. This is important because you need to know the size of your room in order to determine how many diffusers you need.

To calculate the size of your room, you need to measure the length, width, and height of the room. Then, you multiply the length by the width by the height. This will give you the total size of your room in square feet.

Now that you know the size of your room, you can determine how many diffusers you need. The general rule of thumb is that you need one diffuser for every 250 square feet of your room. However, you may need more or less depending on the shape of your room and the type of diffuser you are using.

For example, if you have a rectangular room that is 300 square feet, you would need at least 1.2 diffusers. If you have a room that is square and is 300 square feet, you would only need 1 diffuser.

If you are using an oil diffuser, you may need more diffusers because the oil diffusers cover a larger area than the other types of diffusers.

Now that you know how to calculate the number of diffusers you need, you can go out and buy the right number of diffusers for your room. And, you can rest assured knowing that your room will be properly diffused!
