Komtfil bag air filters have a large surface, so it has a high dust holding capacity, long life, and can effectively improve your indoor air quality.
Komtfil pocket air filters are made of synthetic fibers or glass fibers that are sewn in a V-shape to form a pocket type. They are best-suited for a constant airflow, allowing the pockets to inflate in the air stream and capture dust, airborne particulates, nebulizer droplets, fumes, paints, and oil mist. Bag filters or pocket filters are normally used as pre-filters or secondary filters in HVAC or AHU systems to remove larger particles, so that the second or third stage high-efficiency filters can capture small or fine particles. Hence, they can protect the high-efficiency filters in the 3/4-stage filtration systems in some high-end industries like medical, cleanroom, or Pharmaceutical. This can decrease the filter replacement time and maintenance cost.
Being a leading bag filter supplier, we have more than 20 years in designing and manufacturing the HVAC bag filters. Our industrial bag filters come with low airflow resistance, unbeatable construction, and a competitive price. It will surely cut down your operating costs and prolong the HVAC system’s life.

The plastic frame pocket filter is light and self-supported; they are easy to install with high quality and good performance.

The Metal Frame gives a rigid structure to the pocket filter that can take large air volume. This is also the most used frame type.

When working under high temperature conditions, you must use a fiberglass pocket filter. It is less likely to clog quickly when filtering paint.

Activated carbon materials are also suitable for pocket filters. In chemical gas environments, activated carbon pocket filters are ideal for air filtration.
Komtfil bag filters are double-stitched on the edges and ultrasonically sealed, making them leak-proof. The pockets are firmly sealed with the header to prevent air bypass. We have the full line of filter material options, including non-woven synthetic media, microfine fiberglass, and melt-blown polypropylene, as well as some special materials like activated carbon, moisture-resistant media, and combination media. For the header frame, you can choose plastic, galvanized steel, or stainless steel, which can increase the rigidity of the pocket filter.
As a pocket filter manufacturer, we surely can offer custom and OEM services. From different sizes 12×24, 24×24, and filter media colors(white, yellow, orange, green, blue), we got you covered. For pocket depths, you can choose from 10″ to 36″, and for pocket numbers, 3, 4, 5, 6, 7, 8, 10, and 12 are all optional with coarse filtration, medium efficiency, and high efficiency. What’s more important, we have a short lead time of 7 days for your order.
As a dependable supplier, we do quality checks on our rigid bag filters just to ensure they have superior performance. An extended surface, durable, low-pressure drop, and withstand high humidity make our pocket filter an economical solution in many fields: hospitals, laboratories, food and beverage, paint booths, and other facilities. They can also be used in industrial, commercial, and residential settings. Our pocket filters’ additional surface can capture and remove more contaminants in air handling units, recirculation systems, or Ventilation systems.
6 months. If the working environment is extreme, it should be replaced every 1-3 months.
Bag filters can handle larger air volumes than panel filters, but panel filters require less space for installation and use.
Bag filters can be washed, but should be replaced in time when the bag filter reaches the final pressure drop or is completely clogged.
For the synthetic pocket filter, the final pressure drop is around 350-450 Pa based on its filter efficiency.
