Factory Supplied Customizable Air Purifier G3 G4 Air Pre Filter 6-15Pa With Polyester Fiber Cotton Aluminum Frame For Cleanroom
6-15Pa Primary Air Filter With Polyester Fiber Filter Cotton Aluminum Frame For Cleanroom
A pre-air filter is an initial stage of filtration used in air filtration systems, often in devices like air purifiers, HVAC systems, or even in engines (such as for cars or small machinery). Its primary function is to capture larger particles, such as dust, dirt, and debris, before the air or air stream reaches the main (or finer) filter.
Scope of Application
Prefiltration for central air conditioning and central ventilation systems, prefiltration for multi-stage filtration systems.

Product Characteristics
|
Filtration Efficiency:
- Pre-air filters are designed to capture larger particles such as dust, lint, and hair.
- Typically, they have lower filtration efficiency (e.g., 30–60%) compared to HEPA filters.
Purpose:
- Acts as the first line of defense to protect downstream filters (like HEPA) from becoming clogged by large particles.
- Extends the lifespan of high-efficiency filters by reducing their load.
Material:
- Made from coarse mesh, foam, or synthetic fibers, depending on the application.
Cost:
- Relatively inexpensive due to simpler construction and lower filtration efficiency.
Maintenance:
- Easy to clean or replace; often reusable if washable materials are used.
Applications:
- Commonly used in HVAC systems, air purifiers, and industrial equipment to pre-filter air.
