The air filter in the purification workshop is mainly responsible for removing particulate impurities in the air. When piston type machinery (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter consists of two parts: a filter element and a shell. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. Its use is too wide, such as pharmaceuticals, scientific research, machinery, spraying, electronics, plastics, etc. Air filtration is used in all aspects. The air filter in the purification workshop needs to be replaced after it has been used for a long time. How to identify whether the air filter should be replaced? How to judge whether an air filter should be replaced? First of all, we should judge from the following points:

1. Carefully observe whether the air filter itself is dark or black. If the air filter is obviously black, then the air filter should be replaced at this time.

2. Generally, the air filter that is about to break down will be leaky. If it is found, it needs to be replaced.

3. There is a lot of dust around the air filter, so we need to clean the following at this time. If the effect of the filter is not good after cleaning, then it needs to be replaced.
