How to distinguish the quality of high-flow air filters

　　High flow air filter is the abbreviation for air filter, which is a device that removes particulate impurities from the air. So, let's understand how to distinguish the quality of high flow air filters?

　　High flow air filters are mainly used in fields such as air machinery and internal combustion engine machinery, providing clean air and preventing the inhalation of air with particulate impurities, which increases the probability of wear and damage. The high flow air filter mainly consists of a filter element and a housing, where the filter element is the main filtering part, responsible for filtering the gas, and the housing provides necessary protection for the filter element.

　　What do you know about how to distinguish the quality of high flow air filters?

　　1. Water test. This is also a key and simple identification method. For inexperienced individuals, water can detect the quality of high flow air filters. Place the high flow air filter flat on the ground or table, and sprinkle water on the filter paper. If the filter paper absorbs water within 5 minutes, the high flow air filter made with cotton swabs should not be used.

　　2. If the filter paper absorbs water within 1.2-5 hours, it is made of low-grade wood pulp paper and can be used, but it will affect the air compressor's inflation efficiency (more power consumption, less inflation).

　　3. If the filter paper absorbs water after 12-15 hours, it belongs to qualified filter paper (medium-speed filter paper).

　　4. If the filter paper does not absorb water after 24 hours, it is a premium product (high-grade filter paper).

　　2. Whether it is uniform, whether the light transmittance is good, whether the surface roughness of the filter paper is good. If the filter paper appears uniform and detailed under light observation, has good light transmittance, and good surface roughness, it indicates that the filter paper has good filtering precision and air permeability.

　　3. From the depth and folds of the filter paper, if the filter paper is deep and has many folds, it indicates that the air filter has a large filtering area. The larger the filtering area of the air filter, the greater the dust holding capacity.

　　Whether blowing or not, one should not be arrogant and indulgent. Many owners believe that high flow air filters can continue to be used after being blown with an air gun.

　　These 'experienced drivers' believe that this is both practical and economical, not knowing that air filters have countless harms and no benefits.

　　From a structural perspective, the high flow air filters currently used in cars are generally dry filter elements, with filtering materials mostly being filter paper or non-woven fabric. The fiber layer of the filter material has the function of adsorbing dust particles, and once the fiber layer is damaged, the filtering performance is lost.

　　High flow air filters are like our human noses, with the filtering material resembling the nose hairs, forming a filtering barrier before air enters the cylinder, blocking suspended particles outside the cylinder, ensuring sufficient air intake, and preventing damage to the car engine's power. If the air filter cannot block various dust and particles in the air, the engine will get sick like a human. Of course, just like the human nose, the air filter plays a significant role but is also very fragile. If blown with an air gun, the strong airflow will move dust particles, damaging the filter paper fibers, enlarging the gaps in the air filter mesh, and if blown too hard, it may directly blow away the filter paper. How can such a damaged high flow air filter block dust?

　　Some might say, be careful, if you blow gently, won't it hurt the high flow air filter?

　　What a beautiful thought! Do you know what the main component of dust is? It is mainly silicon dioxide, which is an atomic crystal, a solid that is hard and difficult to melt, and is the main component of quartz (crystal), glass, and ceramics. Small dust particles are harder than iron.

　　No matter how you blow with an air gun, the particles that splatter out will damage the fiber layer, then enter the engine with the air cylinder, causing wear on the piston-related parts, and in severe cases, damaging the cylinder wall, leading to insufficient engine power.
