Smoke and vapor contain resin. Some strains are naturally more resinous and some devices create dense clouds. The Filters were designed to reduce the harshness by removing resin, tar and other contaminants, but eliminating resin and tar completely would be impossible, without eliminating the smoke/vapor. Our goal was to develop a product that provides the best of both worlds. Solid filtration, coupled with strong airflow, to create a more enjoyable experience.
