Most car owners can directly see the number of wrinkles in the air conditioning filter when opening a new air conditioning core. They might think that the more wrinkles there are, the better the filtering performance of the air conditioning filter element is. In fact, there are two main factors that determine the performance of the filter element. First of all, it is the filtration performance of the filter material of the air conditioning filter element. For products with the same filtration area but different filtration materials, there will be significant differences in their filtration efficiency, ash holding capacity, adsorption capacity, antibacterial and anti-allergic capabilities. Second, increasing the folding frequency of the air conditioning filter element within a reasonable range can enhance the filtration performance. However, if the number of folds is too large, it will increase the air resistance of the air conditioning filter element, resulting in insufficient air output.
Many car owners have a deep misunderstanding about activated carbon air conditioning filters. They think that the heavier the activated carbon air conditioning filter element is, the more activated carbon it contains and the better the filtration performance of the air conditioning filter element will be. In fact, this is not entirely correct. The adsorption capacity of activated carbon depends on its internal pore structure, among which the internal micropores play a decisive role, that is, the pores with a diameter of less than two nanometers. The more micropores there are, the larger the surface area, the higher the capacity and the stronger the adsorption capacity. Compared with ordinary charcoal and coal-based activated carbon, coconut shell activated carbon has stronger performance after activation. However, the low-quality and low-priced activated carbon air conditioning filter element, which is made of activated carbon from ordinary materials, has not yet been activated and opened. Even if more activated carbon is added to the air conditioning filter element, there will be no adsorption effect, but it will increase the resistance of the air conditioning filter element and reduce the air intake volume.
