Pocket (Bag) Air Filters

Unlike traditional air filters, which are composed of a single layer of filter media, pocket air filters are constructed with multiple layers of high-quality filter materials. This multi-layered structure enables them to capture a wide range of airborne pollutants efficiently.

Pocket bag air filters are the most common air filters used in HVAC applications. It can be used for air purification,removal of volatile organic compounds,dust,smoke,odor toluene, methanol and other pollutants in the air.

HVAC pocket bag air filters as high efficiency filters in industrial, commercial, medical and institutional applications, mainly used in central air conditioning, environmental protection equipment, ventilation system, to improve indoor air quality and comfort.

Types of industrial bag air filters

Activated carbon porket (Bag) air filter: made by loading negative activated carbon on polyurethane substrate. its carbon content is above 60%, and it has good adsorption per formance.

Primary/Medium  efficiency air bag (pock) filter : use a melt blown ultrathin non-woven fiber filter element and a V bank design structure. They commonly function as the primary air filter in centralized air conditioners and ventilation systems, or as pre-filter for air purifiers.

Multi pockets design, enhanced filtration efficiency

With their intricate design and multiple layers, they can capture particles as small as 0.3 microns, including dust, pollen, pet dander, bacteria, and even some viruses. 

The multi-layered design allows for a larger surface area, which not only enhances the filtration efficiency but also extends the lifespan of the filter.
