The MouthPeace is a filter and personal mouthpiece designed for use with pipes, you can even stick a pre roll in if it's fat enough.
The Moose MouthPeace filter has a carbon filter disc on the inside that is replaceable. The carbon filter helps reduce harshness and filters out resin and toxins without reducing air intake. Besides filtering out the bad stuff, the MouthPeace also covers the top of pipes so you can use it instead of the germ covered surface that your friend just put their lips on.
