After 16 months of R&D, we created the MouthPeace and MouthPeace Filters. Made from biodegradable and recycled materials, the triple-layer activated carbon filters sanitize smoke/vapour and enhance flavours by removing resins, contaminants, and tar; all without blocking your intake or reducing airflow. Replace Filter as needed for optimal performance. See and feel the difference. Kit includes MouthPeace, 3 Filters, and lanyard.
