These reusable silicone mouthpieces are perfect for removing harmful particles from smoke so that you can enjoy the flavor and the vibe with less damage to your lungs. The new MouthPeace Mini is easier to use than ever with two different sized openings for use with pre-rolls (smaller end) and vaporizers (wider end). Using a triple-layer activated carbon filter, the MouthPeace removes resins, toxins, and tars from smoke while retaining flavor and without blocking airflow. Made from bidegradable and recycled materials, these filters are easily replaceable.
