Surface area significantly impacts performance - a standard 24x24x22 (8 pockets) filter provides approximately 60 sq ft of filtration media, while larger configurations can exceed 100 sq ft. Typical service life ranges from 6-12 months depending on pre-filter maintenance and air quality.
Application Guidelines
Pocket filters maintain consistent airflow through their pocket design. They are ideal for systems operating continuously (24/7) but not recommended for variable air volume systems where frequent shutdowns occur. All Compo pocket filters undergo rigorous testing to meet ASHRAE 52.1, EN779, and ISO16890 standards, ensuring low initial pressure drop and extended service life.
