A pocket filter, also known as a bag filter, is a type of medium to high-efficiency air filter commonly used in HVAC systems to capture dust, pollen, and airborne particles. Its multi-pocket design provides a large filtration surface area, allowing for higher dust holding capacity and longer service life. 

Nanofiltech’s pocket filters are made with synthetic fiber or composite nanofiber media, focusing on stable filtration performance, low pressure drop, and energy efficiency. Designed for cleanroom pre-filtration, hospital ventilation, and general air management, our filters are available in various sizes and configurations to meet diverse application needs without adding unnecessary complexity.

Nanofiltech's pocket filters feature a robust all-metal frame construction, a low air resistance design that reduces operational pressure drop, and a fluffy multi-component material that optimizes dust holding capacity and filtration efficiency, offering an excellent cost-performance ratio while being customizable in size, pocket depth, filtration grade, and frame material for various applications like cleanroom pre-filtration, hospital ventilation, and general building air handling units.
