It is necessary to test its efficiency.

1. Gravity method is the simplest way to measure filtration efficiency. This method is mainly used in the filter element inspection of coarse and medium-efficiency air filters. The test method is very simple, mainly to put the filter element in the test. In the wind tunnel, after a period of time, dust will be released, and the dust content absorbed by the filter element will be recorded, so that the filtration efficiency of the filter element can be checked.

2. The colorimetric method is usually used in the detection of the filter element of the medium-efficiency filter. When measuring, it is necessary to take the dust of more than one micron as the measuring substance. Use filter paper to sample before and after filtration. After adopting, place the filter paper under the light source and use electricity. The tube density meter is used to measure, so that you can understand its filtration efficiency in detail, but you must pay attention to the dust composition and the size distribution of the particle size when measuring.

3. The particle counter method is the most frequently used method for measuring the filtration efficiency of air filter elements. This is mainly because of its high accuracy. It is widely used in high-demand areas such as clean rooms. Use this test method to measure. As long as the air containing dust is used for strong light illumination, light will be scattered when the dust passes through the filter, thereby forming a pulse signal, so that the data of the filter efficiency of the filter can be obtained.
