A 3 Pocket Synthetic Bag Filter is an extended surface HVAC filter constructed with three ultrasonically sealed synthetic media pockets to maximize dust-holding capacity and airflow efficiency. Its non-carcinogenic, moisture-resistant polypropylene layers trap fine particles while maintaining low pressure drop, making it ideal for multi-stage filtration systems. Common applications include hospitals, commercial buildings, and spray booths where consistent air quality and long service life are critical.
