HOW FÜM WORKS
How Does
FÜM Work?
FÜM uses your natural breath to move air through a replaceable Flavor Core inside a reusable device. Adjust the airflow, draw through the mouthpiece and experience flavored air without a charging routine.
Insert a compatible Flavor Core, close the device, adjust the airflow and draw naturally through the mouthpiece. Air passes through the Core before reaching you.
Add a Flavor Core
Open the FÜM device and place a compatible Flavor Core into the cradle inside the mouthpiece.
Set the Airflow
Close the device and rotate the barrel to adjust the air resistance to the draw you prefer.
Breathe Flavored Air
Draw naturally through the mouthpiece. Your breath pulls air through the Flavor Core to create the flavored-air experience.

How Do FÜM
Flavor Cores Work?
A Flavor Core is the replaceable part of the FÜM system that sits inside the reusable device. As air moves through the Core, it carries the selected flavor profile through the mouthpiece.
Inside the Mouthpiece
The Flavor Core sits in the Core cradle inside the FÜM mouthpiece.
Air Passes Through
Your natural draw moves air through the inserted Core before it reaches the mouthpiece.
Change the Core
When the flavor becomes too subtle for your preference, remove the used Core and insert another compatible Core.
Explore Another Flavor
Keep the reusable FÜM device and change Flavor Cores when you want a different flavor profile.
Flavor intensity and duration can vary with frequency of use and individual flavor perception.
