Moose Labs 10PC Mouthpeace Filter RollActivated carbons antibacterial properties absorb resins, toxins, and tar. They enhance the flavor of your smoke or vape by removing the harsh stuff. Triple layer filters do not reduce airflow or block your intake. Using the no touch design, eject the filter by pushing it up and out with your thumb from the side of the MouthPeace. Replace as needed for optimal performance.
