When purchasing a new car, the service life of various filter equipment should be considered. Details determine success or failure, and filters can definitely be considered as the details that affect vehicle performance and service life.
Firstly, the editor will popularize knowledge about the service life of filters:
The service life of a filter is basically expressed in kilometers, such as 5000 kilometers for an oil filter and 10000 kilometers for an air filter. In fact, these are all relative, and the mileage recommended by the manufacturer is only a relative value. He refers to the analog quantity obtained when testing with standard dust under simulated laboratory conditions. If the lifespan of a filter is expressed in an absolute value, it is the dust holding capacity or capacity of the filter.
Let's take a look at the core component of the filter, which is the heart of the filter:
In automotive filters, whether it is oil filters, air filters, fuel filters, or air conditioning filters, paper is basically used as the filtering medium.
The filter paper used in large brand filters has a thickness between 0.5-0.8mm, and the three-dimensional structure of the filter paper can be seen under the microscope. Paper fibers only occupy 10% -15% of the volume space, and pores of different sizes make up the rest of the space, which we call pores. The manhole is used to hold dust, and when the manhole is filled with dust and the pressure difference of the filter reaches the critical point of damage, it also reaches the end of its lifespan.
So an important factor affecting the lifespan of the filter is the quality of the filter paper used, whether the volume ratio of the space occupied by the filter paper holes meets the requirements, otherwise a large filtering area will have no effect. Secondly, the filtering area of the filter paper is also an important factor. High quality filter paper greatly improves the filtration accuracy while extending the service life of the filter.
