The Smokebuddy is a handy, and reliable, life saving air filter. Simply exhale your smoke through your easy-to-use Smokebuddy and odorless air comes out the other end. Smoke where you want, and when you want without anyone knowing the wiser. Keep second hand smoke away from friends, family, and neighbors with your Smokebuddy. The Original lasts for at least 300 big puffs and Junior for at least 200. They are perfect to use inside, in the student dorm, in your room or other closed spaces where you don't want the smoke to smell everywhere.
