At Afility Industrial Filters Pvt. Ltd., Pocket air filters, also known as bag filters, are an integral component of HVAC (Heating, Ventilation, and Air Conditioning) systems used to maintain indoor air quality in various environments, including residential, commercial, and industrial spaces. These filters are designed to capture and remove airborne particles, contaminants, and pollutants from the circulated air, thus promoting a healthier and more comfortable indoor environment.
The term "pocket" refers to the distinctive design of these filters, which consists of multiple individual pockets or compartments arranged in a grid-like pattern. Each pocket is made from a filter media material that is selected based on its filtration efficiency and particle capture capabilities. Common filter media include synthetic fibers, fiberglass, and other materials with varying levels of filtration efficiency.
Pocket air filters are available in different classifications based on their Minimum Efficiency Reporting Value (MERV) ratings. The MERV rating indicates the filter's ability to capture particles of different sizes, ranging from larger dust and pollen particles to smaller bacteria and viruses. Higher MERV ratings indicate a higher level of filtration efficiency, making them suitable for environments where better air quality is essential, such as hospitals, laboratories, and cleanrooms.
Pocket filters typically consist of multiple layers of filtration media arranged in a pocket-like structure. This design allows for better filtration efficiency compared to standard panel filters. They can capture smaller particles, including dust, pollen, mold spores, and even bacteria and viruses, improving indoor air quality significantly.
The pocket design allows for a larger surface area of filtration media, which means they can hold more contaminants before needing replacement. This longer service life reduces maintenance frequency and cost, making them cost-effective in the long run.
