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.

QUICK ANSWER Core + Airflow + Breath.

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.

01 INSERT

Add a Flavor Core

Open the FÜM device and place a compatible Flavor Core into the cradle inside the mouthpiece.

02 ADJUST

Set the Airflow

Close the device and rotate the barrel to adjust the air resistance to the draw you prefer.

03 DRAW

Breathe Flavored Air

Draw naturally through the mouthpiece. Your breath pulls air through the Flavor Core to create the flavored-air experience.

01 / POWER No Charging
02 / CORE Replaceable
03 / AIRFLOW Adjustable
04 / OUTPUT Flavored Air

INSIDE THE DRAW

What Happens
When You Draw?

There is no battery-powered heating stage in the FÜM airflow path. Your breath moves air through the device, across the Flavor Core and through the mouthpiece.

01 AIR IN

Air Enters

Your natural draw pulls air into the reusable FÜM device.

02 FLAVOR CORE

Air Passes the Core

Air moves through the inserted Flavor Core, creating the flavored-air experience.

03 MOUTHPIECE

Flavored Air Reaches You

The air continues through the mouthpiece as you complete the draw.

THE KEY DIFFERENCE Airflow, not heating.
01

No battery-powered heating process

02

No traditional vape vapor

03

Replaceable Flavor Core

The Flavor Core is the part of the system that creates the individual flavor profile.

FÜM FLAVOR CORES

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.

When the flavor becomes too subtle for your preference, remove the used Core and insert another compatible Core.

04

AIRFLOW & DEVICE

One System.
Your Preferred Draw.

The reusable FÜM device lets you adjust air resistance by changing the airflow through the device. Prominent and Solano use the same basic FÜM system while offering different materials and finishes.

ADJUSTABLE AIRFLOW AIR RESISTANCE

LESS AIR More Resistance
MORE AIR Lighter Draw
01
ROTATE

Adjust the Device

Rotate the adjustable portion of the device to change the amount of airflow available during your draw.

02
DRAW

Find Your Preference

Different airflow settings change how much resistance you feel when drawing through the mouthpiece.

03
KEEP

Same Reusable System

Changing airflow does not require changing the device or Flavor Core system.

TWO DEVICE DIRECTIONS Prominent or Solano?

Both use the same core FÜM airflow and Flavor Core system. The main difference is the material and finish you prefer.

Choosing between the two? Compare materials, finish and visual character side by side.
