When cleaning the filter element in an air filter combination, do I need to clean it in the opposite direction of the air flow?

When cleaning the filter element in an air filter combination, it is usually recommended to clean it along the airflow direction of the filter element, rather than against the airflow direction. This is because cleaning along the airflow direction can more effectively remove dirt and particles from the filter element, while reducing damage or destruction to the filter element structure.
Cleaning in the opposite direction of the airflow may push dirt and particles on the filter element deeper, rather than effectively removing them. This may cause the surface of the filter element to appear clean, but in reality, there are still blockages and dirt, which can affect the filtration efficiency.
In addition to cleaning methods, it is also necessary to pay attention to the replacement cycle of the filter element. The filter element is an important component in air filters, and its performance directly affects the filtering effect of the filter. Therefore, regular inspection and replacement of the filter element are key to maintaining the normal operation of the air filter.
Cleaning the filter element is an important step in maintaining the performance of the air filter combination, but please note that cleaning is not always applicable to all types of filters. Some filters may require replacement rather than cleaning, depending on their material and design
