NOVELTY - A glass fiber air filter material comprises a modified nonwoven fabric and a glass material fiber from bottom to top, formed into a composite by hot-pressing. USE - Glass fiber air filter material is used for purifying air in automobiles (claimed). ADVANTAGE - The air filter material effectively purifies air quality inside automobiles, and has a relatively high carbon loading amount, stable adsorption performance as activated carbon is uniformly adsorbed on the nonwoven fabric material without omission, and excellent mechanical strength and stable size due to the use of glass fiber nonwoven fiber.
