• ULPA(Ultra Low Penetration Air） grade, HEPA（High Efficiency Particulate Air） grade, and semi HEPA grade are available.
• Better balance between pressure drop and dust collection efficiency compared with glass fiber filters and electrets filters.
• Superior chemical resistance, moisture resistance, water resistance, dust release properties, resistance to acids (such as hydrofluoric acid), alkali, and organic solvents.
• The Dust can be released easily with mechanical vibration or brushing.
• No self-dusting characteristics, as glass fiber filters.
• Performance does not degrade with washing.
• No boron, phosphorus, or impurities.
• Low pressure drop and high dust collection efficiency.
