Why Does Your Diffuser Leak from the Air Intake When Filled to the Max Line?
Have you ever filled your scent diffuser's oil bottle right up to the maximum line, only to notice oil mysteriously leaking directly out of the air intake hole once it starts running? It is a common puzzle for many users. At kevinleo, we want to help you understand the simple physics behind your device so you can keep your machine running cleanly and efficiently.
The Science Behind the Leak
Modern cold-air diffusers rely on internal air pressure to atomize essential oils. When the machine operates, the generated air pressure enters the bottle and can squeeze the essential oil out if the container is overfilled.
Practical Advice
To prevent this issue, it is not recommended to fill the essential oil too full; always leave a proper amount of headspace to allow air pressure to circulate without forcing liquid out of the intake hole.
