Abstract
An air purifying filter includes a modified enzyme immobilized on a surface of a carrier. The modified enzyme has been modified with a bonding agent that improves bonding. The surface of the carrier has not been rendered to be water repellant prior to immobilizing the modified enzyme on the surface of the carrier. The bonding agent improves bonding of the modified enzyme to the carrier.
