Wrong fold number of air conditioning filter element
Most car owners can directly see the number of wrinkles of the air conditioning filter element when they open the new air conditioning core. They may think that the more wrinkles, the better the filtering performance of the air conditioning filter element. In fact, there are two main factors that determine the performance of the filter element. The first is the filtering performance of the filter material of the air conditioner filter element. For products with the same filtering area and different filtering materials, their filtering efficiency, ash holding capacity, adsorption capacity, antibacterial and anti allergic capabilities will be very different. The second is to increase the number of folds of the air conditioning filter element within a reasonable range, which can improve the filtering 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.
Gram weight of activated carbon
It is believed that many car owners have a deep misunderstanding about the activated carbon air conditioning filter element. They feel that the heavier the activated carbon air conditioning filter element is, the more active carbon it contains inside, the better the filter performance of the air conditioning filter element will be. In fact, it is not completely 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 pore diameters smaller than two nanometers. The more micropores, the larger the surface area, the higher its capacity and the stronger its adsorption capacity. Compared with the common wood carbon and coal activated carbon, coconut shell activated carbon after activation has stronger performance. However, the low-quality and cheap activated carbon air conditioning filter element is made of activated carbon made of ordinary materials, which has not been activated and opened. Even if more activated carbon is added to the air conditioning filter element, it will not have adsorption effect, but will increase the resistance of the air conditioning filter element and reduce the air intake.
