The Smokebuddy MEGA is our biggest air filter to keep the air clean. It's got a filter that's twice as big as the one in the Original Smokebuddy. Its flat shape makes it easy to hold and it looks really cool. Each Smokebuddy MEGA comes with a special Mr. MegaBuddy LED keychain that lights up when you squeeze it. This air filter can last for months, or maybe even years, for frequent users. It's super easy to use—just breathe out your smoke into the Smokebuddy MEGA, and fresh air comes out the other side. You can smoke wherever and whenever without anyone noticing. With your Smokebuddy MEGA, keep smoke away from your friends, family, and neighbors.
