Top 10 G4 Bag Filter Manufacturers in China 2025

Introduction to G4 Bag Filter

G4 bag filters are a type of air filter commonly used in ventilation and air - conditioning systems. They are designed to capture large particles such as dust, pollen, and lint. With a filtration efficiency typically ranging from 90% to 95% for particles in the size range of 5 - 10 micrometers, G4 bag filters play a crucial role in maintaining good air quality in various indoor environments, including commercial buildings, industrial facilities, and residential complexes. These filters have a bag - like structure, which provides a large filtration area and allows for a relatively high dust - holding capacity, thus extending the service life of the filter and reducing the frequency of filter replacement.
