Internal structure of air filter element

The internal structure of the air filter element usually includes the following parts:
Filter material: The filter material is the core part of the filter element and is generally made of paper or synthetic fiber. The main function of the filter material is to filter dust, sand, insects and other particulate matter in the air to protect the engine from pollution and wear. The performance of filter material depends on factors such as material type, density and fiber diameter.
Protective net: The protective net is generally located on the outside of the filter element to prevent damage to the filter material and entry of external debris. The protective mesh is usually made of metal mesh or plastic mesh, and its pore size matches that of the filter material.
Interface part: the interface part is the part connecting the filter element and the air filter box. Generally, there are rubber sealing rings or metal gaskets and other sealing materials to ensure the tightness between the filter element and the air filter box.
Coil: The coil is usually located on the outside of the filter material to strengthen the structure of the filter element and improve its pressure resistance. The coil is generally made of metal wire, and some parts are made of plastic coil.
The internal structure of the air filter element can vary according to different brands and models, but generally includes the above parts. The performance and filtration efficiency of the filter material are important factors affecting the quality of the air filter element. Selecting the appropriate filter material and filter element structure can effectively improve the service life and filtration effect of the filter element.

Selection of air filter element

The selection of the appropriate filter element needs to consider many factors, including the air quality in your home, the brand and model of the air filter, the type and specification of the filter element, etc.
First of all, you need to know the air quality in your home. If there are pets, smokers, vehicle exhaust and other factors in your home, it is recommended to select a high-efficiency filter element that can filter PM2.5, VOC, formaldehyde and other pollutants.
Secondly, you need to select the corresponding filter element according to your air filter brand and model, because different brands and models of air filters use different types and specifications of filter elements.
Finally, you can select the appropriate filter element according to the material, filter efficiency, service life, price and other factors of the filter element. In general, the better the filter element material, the higher the filtration efficiency and the longer the service life, the higher the price of the filter element.
It is recommended that you read the product manual and relevant evaluation carefully when purchasing the air filter and filter element, and select the product that is suitable for the use environment and budget.

Replacement of air filter element

The filter element of the air filter needs to be replaced regularly according to the use and the type of filter element. Generally speaking, the replacement cycle of filter element is about 3-6 months, but the actual situation may vary due to the different use environment and frequency.
If the air quality is poor, the use frequency is high, or there are pets at home, it is recommended to replace the filter element more frequently to ensure the filtering effect.
At the same time, different brands and models of air filters use different types of filter elements, so it is necessary to understand the replacement cycle and method of filter elements according to specific product instructions. Generally speaking, the replacement of the filter element of the air filter is very simple. It only needs to remove the old filter element and install the new filter element.
