Primary Efficiency Air Filter G4

August 07, 2023

The G4 primary air filter is a type of air filter used in cleanrooms and ventilation HVAC systems. It is a primary efficiency filter with high filtration efficiency and effective air purification capabilities. This article will provide you with a detailed introduction to the meaning and performance characteristics of the G4 primary air filter.

The G4 primary air filter is commonly used in cleanrooms and ventilation HVAC systems. It is primarily designed to filter out particulate matter from the air and offers effective filtration results. Filters rated as G4 can efficiently capture particles larger than 5 micrometers in diameter, such as dust, pollen, and fibers. They are widely employed in environments like large shopping malls, hospitals, electronic factories, and food processing plants, where air purification is essential.


The performance characteristics of the G4 primary air filter are as follows:

1. High Filtration Efficiency:

The G4 primary air filter, rated at G4 efficiency, offers a high filtration capacity that effectively removes particles larger than 5 micrometers, ensuring that the particle concentration in the air meets reasonable standards. This is crucial for maintaining a clean and healthy air environment in cleanrooms and HVAC systems.

2. Low Resistance:

The G4 primary air filter utilizes high-strength glass fiber filter paper or synthetic fiber filter materials, providing excellent airflow performance and low resistance. When integrated into ventilation systems, it reduces energy consumption and noise while enhancing system efficiency.

3. Long Service Life:

The filtration media of the G4 primary air filter is constructed from high-quality glass fiber filter paper or synthetic fiber materials, offering durability and resistance to aging. Under normal usage conditions, the G4 primary air filter can last for over 6 months, making it cost-effective.

4. Easy Installation:

The G4 primary air filter is typically designed in a box-shaped structure with standardized frame sizes, ensuring easy installation. It can be combined with other types of filters to create a multi-stage filtration system, enhancing the overall filtration efficiency.


The G4 primary air filter is extensively used in cleanrooms and ventilation HVAC systems due to its efficient filtration, low resistance, long service life, and ease of installation. It effectively filters out airborne particles, ensuring air cleanliness and healthiness. When selecting a G4 primary air filter, it's essential to choose the appropriate specifications and models based on your specific requirements and environmental conditions.
