Most car owners think that extending the cycle of replacing air-conditioning filters and air filters can reduce the cost of using a car. A phrase they often hear at 4S stores or repair shops is that if you blow it with an air gun for me, I'll replace it next time.
However, with the air gun blowing clean filter, the filter is only clean surface, in fact, the filtering effect is still very poor, the replacement filter or to be replaced.
It should be noted that HEPA filters are only very effective for the filtration of fine particles in air conditioning filters, such as PM2.5, as we often mentioned. But this kind of filter has no obvious effect on odor and harmful gas. So we need to mix with other filter materials.
Air conditioning filters vary greatly in material quality.
Nonwoven fabric
Non-woven fabrics are widely used in our daily life, such as masks, diapers, household goods and clothing will appear in the shape of non-woven fabrics. However, when it is used as the filter layer of air conditioning filter, it can only filter the dust, gravel, willow catkins and other particles with the size of 5 micron, and has no obvious effect on harmful gases and odors. Of course, nonwoven filters are very cheap, ranging from a dozen to dozens of dollars, but in the face of today's complex environment, it is not recommended to use.
