This will be the question we will answer in this paragraph. So as to orient your choice well towards a model that can satisfy your needs. Let’s see together, then, the parameters to be taken into consideration.
How big is the room you want to perfume?

So remember: the more powerful your ultrasonic diffuser is, the larger the room you want to perfume can be.

The electric diffuser must always be connected to the mains, and this allows continuous use until the water runs out. It is important that the product is equipped with the “automatic shutdown.”
Ultrasonic battery diffuser
The battery air fresheners are among the most innovative products as they allow a connection both to the electrical socket and without (not all of them, however, read carefully in each model that the presence of the cable is not there only to recharge the battery). However, it must be specified that the autonomy without cable connection is certainly not high. But they can certainly be used anywhere.

Of course, you could also leave it on until the water runs out.
Container size and design
