Does the car air conditioner filter need to be replaced if it is dirty?

Air conditioner filters need to be replaced regularly.
In fact, the principle and structure of the car's air-conditioning system is almost the same as that of the household air-conditioning system. If you have disassembled a household air conditioner, you must know that there are 2 filter screens under the panel. The function of these two filters is of course to block and filter the dust in the air.
After a long period of use, if you remove the two filter screens of the household air conditioner, you will definitely find that the filter screen is almost blocked by dust, and the air output of the air conditioner is getting smaller and smaller. The filter screen of the household air conditioner can be removed and cleaned, and then installed back.
The same is true for cars, but the car's air-conditioning filter is a one-time use. We generally call it the car air conditioning filter. After long-term use, the surface of the filter screen is completely blocked by impurities and dust, and the wind force at the air outlet of the car becomes smaller and smaller. The cooling effect is reduced, and even the filter screen is moldy and causes peculiar smell. Therefore, it needs to be removed regularly to replace the new filter screen.
