Examples include small molecules, salts, carbohydrates, amino acids, fatty acids and steroids. Does not contain proteins, hydrolysates, or other ingredients with a complex structure or unknown composition.Chemical Media | PurafilMolecular Media. Purafil’s patented, spherical, porous pellets remove gaseous pollutants from the air through a unique chemical process known as chemisorption. During chemisorption, the media converts harmful gases from the air into harmless materials that are trapped inside the pellet. This process is instantaneous and irreversible. Request Info
