FlexPuff

As the name suggests, FlexPuff enables more flexible experience compared to previous IQOS devices. The feature may provide you with 4 extra puffs.*

FlexPuff automatically adapts to you based on your individual usage patterns, so you don't have to worry about activating it yourself. 

Some advantages of FlexPuff include:
• An adaptive experience for enhanced experience
• Optimal stick usage and a longer stick duration

*FlexPuff activation and number of puffs depend on individual usage patterns, thus extra puffs might not apply to all adult consumers and/or experiences. FlexPuff does not activate when pause is used.
