Frequently Asked Questions about Air Filter

In view of the 100,000 series of air-conditioning filters, why the series is widely praised, so Xiao Bian will continue to launch other articles of the same series of three filters, to answer your doubts, and welcome everyone to leave a message, we will answer in subsequent articles.

This time we open the air filter chapter ~

Q: Why can’t air filters come in all shapes and sizes?
A: The overall size of the air filter generally depends on the layout of the engine compartment of the vehicle. Generally, the design of the air filter is generally a “dojo inside a screw shell”. The size of the filter element must be controlled within the specified limited space. At the same time meet the working requirements of the engine. For example, the latest application of MANN + HUMMEL and the Mercedes-Benz series of air filter Flexline, make the most of the space.IMG_4569

Q: Why do some air filters have a layer of sponge, and some do not?
A: In order to adapt to the severe working conditions of some models, MAN filters have some air filters with “sponge”. In fact, this is a pre-filter layer. In areas with severe dust, in order to prevent the filter from being blocked by coarse ash prematurely, the pre-filter layer can isolate the coarse ash first, and only fine ash will enter the filter paper to ensure the service life of the air filter. In addition, in cold regions, due to rain and snow weather, snow water will enter the air filtration system, and the sponge layer can also well block the damage of water to filter paper.

Q: Can I take the air filter out and blow the dust, can I continue to use it?
A: Many people will do this. In fact, this does not help to extend the working time of air filtration. Due to the principle of deep filtration, you only blow off the coarse gray on the surface, but the fine gray that really hurts the engine has already been attached to the deep layer of filter paper. It is not “blowable” as imagined, not to mention that it may be improperly operated and “blown” more dust into the filter paper, which will reduce the life of the filter element.
