Pocket and Bag Filters for AHU and HVAC Systems
In an AHU, the pocket filter usually sits behind a coarse pre-filter and does the F5–F9 work. We make non-woven and polyester bags from G4 to F9, plus rigid pockets for higher airflow and carbon pockets when odor is part of the spec.
Pocket count, depth and header follow the housing — standard or custom sizes, with batch test reports if you need them.

FAQ
What does a bag filter do in an HVAC system?
It carries the fine filtration stage. In a typical air handling unit a coarse panel pre-filter catches large dust, then the pocket or bag filter — usually F5 to F9 — removes fine particles before air reaches coils, ducts or a final HEPA stage. Multiple deep pockets give it several times the media area of a flat filter, so it holds more dust at lower pressure drop and runs longer between changes.
Pocket filter or bag filter — is there a difference?
No — they are the same construction under two names: a header frame with sewn media pockets, and both terms are used interchangeably across markets. Specify the grade (G4-F9), face dimensions, pocket depth and pocket count, and you'll get a like-for-like quote whichever term you use.
What micron size does an AHU bag filter capture?
Bag filters aren't rated by a single micron cut-off — efficiency is graded against particle-size fractions. Under ISO 16890 an F5 pocket captures 50–60% of ePM10 (particles up to 10 μm), while F7-F9 pockets capture 50% to over 80% of ePM1 (최대 1 μm). Match the grade to the downstream air quality your specification calls for.
Do you make fiberglass and synthetic pocket filters?
예. Pocket media options cover non-woven synthetic, polyester and fiberglass, plus activated carbon media for odor and VOC duty. Polyester bags are a frequent choice where hygiene matters — a large-scale food factory runs our polyester fiber filter bags for their low resistance and high dust-holding capacity.
What is your MOQ and lead time for pocket filters?
MOQ에서 200 조각들. 무료 샘플 배송 3 날; 표준 주문 후 영업일 기준 7~10일; 15~20일 내 대량 또는 맞춤 주문, 긴급 교체를 위한 녹색 채널 포함.
Can you build custom pocket counts, depths or header frames?
Yes — pocket count, 주머니 깊이, face size, media grade and header frame (알류미늄, 아연 도금, 스테인레스 또는 ABS) are all production variables, 필요한 경우 개인 라벨 포장 포함. When Midea's filters clogged too fast, our engineers re-tuned the media pore density to raise dust-holding capacity and cut resistance — the same development support is available for OEM programs.
