The function of an air filter: The engine needs to suck in a large amount of air during operation. If the air is not filtered and the suspended dust in the air is sucked into the cylinder, it will accelerate the wear of the piston group and cylinder.
Large particles entering between the piston and cylinder can cause serious cylinder pulling, especially in dry and sandy working environments. The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder.

The use of paper core air filters in modern car engines is becoming increasingly common, but to this day, some drivers still have a bias towards paper core air filters, believing that their filtering effect is not good. In fact, paper core air filters have many advantages compared to oil bath air filters:
Firstly, the filtration efficiency is as high as 99.5% (98% for oil bath air filters), and the dust transmission rate is only 0.1% -0.3%;
Secondly, it has a compact structure and can be installed in any direction without being limited by the layout of vehicle components;
Thirdly, maintenance does not consume oil and can also save a large amount of materials such as cotton yarn, felt, and metal materials;
The fourth is low quality and low cost. Therefore, drivers can use it with confidence.
