Activated Charcoal Sploof

thingiverse

When combined with a common coffee machine water filter, this device helps a smoker to prevent any smoke exhaled from escaping into the air. The filters are available on Amazon; just search for "Braun coffee machine filters". The activated charcoal absorbs a vast majority of the smells. Simply place the activated carbon filter into the end of the sploof then cover with the cap. Exhale into the sploof then repeat. :)
