Economical Primary Filter Media for HVAC & Industrial Dust Filtration

A: The WFB Primary Efficiency Filter Media is a versatile, cost-effective pre-filtration material designed for air purification systems. It is available in thin (needle-punched, 1–8mm) and thick (hot-air bonded, 0.5–8cm) variants, offering low initial resistance, high dust-holding capacity, and flexibility for a wide range of industrial and commercial applications.

Dual Construction Options:

Thin: Needle-punched (1–8mm)

Thick: Hot-air bonded (0.5–8cm)

Key Performance: Economical, low resistance, high dust-holding capacity, elastic, safe, and easy to use.

Primary Filtration: Primarily filters ≥5μm particulate dust and suspended solids in the air, serving as a common pre-filter in air purification systems.

Washable Reusability: Washable variants can be rinsed with water or detergent, then air-dried for reuse (up to 2 washes, with a 15% efficiency drop per wash).

It is widely used in:

Industrial Processes: Spray coating, electroplating, surface treatment, waste gas treatment, and anti-pollution industries.

HVAC & Ventilation: Building ventilation, air conditioning, and public construction projects.

Manufacturing: Home appliances, automotive, motorcycle, electronics, watchmaking, pharmaceuticals, food, packaging, furniture, and decoration industries.
