Features：
1. High-loft layered melt blown synthetic media, stronger than fiberglass, better filtration performance with large dust holding capacity
2. Ultrasonically-welded pocket configuration that guarantees complete pocket inflation and eliminates crowding or leakage
3. Non-shedding and water-resistant media
4. Between each pocket there is a metal stick to make frame firm, and the PP separator in each filter bag distributes the air flow evenly, avoiding excessive expansion of the filter under the pressure.
Application: Pocket filter are usually used for commercial and industrial HVAC pre-filtration.
1. Clean room fresh air conditioning system, the middle section of fresh air units
2. Ideal choice for secondary or end of line filtration of central air conditioning system
3. Main filter of air purifier
4. Pre-filtration ahead of a HEPA filter
