Fine Filter

Product Details:

A Fine Filter is a medium-efficiency air filter that removes 1–5 micron particles from the air. Installed after the Pre Filter and before the HEPA Filter, it protects the system from fine dust, aerosols, and suspended PM.

It is commonly used in pharmaceuticals, healthcare facilities, electronics manufacturing, laboratories, food industry, and commercial HVAC systems.

• High efficiency grades: F5, F6, F7, F8, F9 (ISO 16890 → ePM1 / ePM2.5 / ePM10)

• Large filter area for high dust holding capacity

• Low pressure drop for energy savings

• Available in Box Type, Flange Type, and Mini-Pleat Models

• Media Options: Synthetic, Microfiber Glass, Non-woven

• Rigid construction — prevents media collapse

• Suitable for variable air velocity in AHU/MAU/FAUs  

Removes fine dust, PM2.5, spores, bacteria-carrying particulates, enabling clean, breathable air.

Extends HEPA filter life by capturing medium-size particulates before they reach the HEPA stage.

Low resistance design ensures optimized power consumption by the AHU motor.

More pleats = more surface area = longer life and fewer replacements.
