How blu Works

Get an intro to how blu eCigs® products work.

  • Technology. Simplicity. Satisfaction.

    So, how exactly do blu eCigs electronic cigarettes work? How do they provide satisfaction without the smoke or ash of traditional cigarettes? We're here to let you know about all of that.

    The Simple Science Behind E-cigs


    E-cigs heat liquid instead of burning paper or tobacco. The liquid is converted to vapor, so there’s no smoke. The blue light tip lights up to show you’ve got a charge—and to let people know you’re vaping. Here’s what happens when you inhale:

    • Taking a draw activates the battery
    • The battery power heats the liquid
    • The liquid is converted into vapor
