Classification standard for air filter elements

The air filter is an important equipment that cannot be separated from the modern society. Its filter element is the key part to filter out the pollutants in the outside air. Therefore, the classification standard of the filter element has always been valued by the industry. The grade classification standard of air filter elements is mainly based on the grade of pollutant particles blocked. Generally speaking, the classification standards of filter elements can be roughly divided into five types, namely G1 grade, G2 grade, G3 grade, G4 grade and G5 grade.

The air filter is an important equipment that cannot be separated from the modern society. Its filter element is the key part to filter out the pollutants in the outside air. Therefore, the classification standard of the filter element has always been valued by the industry. The grade classification standard of air filter elements is mainly based on the grade of pollutant particles blocked. Generally speaking, the classification standards of filter elements can be roughly divided into five types, namely G1 grade, G2 grade, G3 grade, G4 grade and G5 grade. G1 grade represents the lowest grade, and the filtration accuracy is above 5um. G2 grade means low-to-medium grade, and the filtration precision is above 3 μm. G3 grade means medium grade, and the filtration accuracy is above 1 μm. G4 grade means medium and high grade, and the filtration accuracy is above 0.5um. G5 grade represents the highest grade, and the filtration accuracy is above 0.3μm. G1 grade filter elements can effectively filter out pollutants with visibility greater than 5m, but the effect is not very good for pollutants less than 5m, so G1 grade filter elements are suitable for relatively loose environments, such as factory workshops and other occasions. G2 grade filter elements can effectively filter out pollutants with visibility greater than 3m, but the effect is not very good for pollutants less than 3m, so G2 grade filter elements are suitable for more formal environments, such as home and other occasions. G3 grade filter elements can effectively filter out pollutants with a visibility greater than 1m, but the effect is not very good for pollutants less than 1m. Therefore, G3 grade filter elements are suitable for general indoor environments, such as homes and offices. G3 grade filter elements can effectively filter out pollutants with a visibility greater than 1m, but the effect is not very good for pollutants less than 1m. Therefore, G3 grade filter elements are suitable for general indoor environments, such as homes and offices. G4 grade filter elements can effectively filter out pollutants with a visibility greater than 0.5m, and have a certain filtering effect for pollutants less than 0.5μm. Therefore, G4 grade filter elements are suitable for more demanding environments, such as hospital wards and other occasions. G5 grade filter elements can effectively filter out pollutants with a visibility greater than 0.3m, and also have a better filtering effect for pollutants less than 0.3μm. Therefore, G5 grade filter elements are suitable for the most demanding environments, such as aircraft, ships, and heavy industry factories. occasion. Therefore, the classification standard of air filter elements is based on the fact that the filter elements can effectively block pollutants in the outside air, and then provide suitable air filtration effects for different environments. The filter elements are mainly divided into G1 to G5 according to the filtration accuracy. five levels. At the same time, because the precision of blocking pollutants of different grades of filter elements is not the same, so when choosing an air filter, the correct choice should be made according to the actual environmental requirements to ensure the cleanliness of the air.
