The quality of the air filter is good or not, mainly depends on the following three aspects:

1. Waterproof performance;
2. Filtration accuracy;
3. Air permeability.

Generally speaking, detection has the following methods:

1. Water test. Put the air filter flat on the ground or table, sprinkle some water on the filter paper;

a) If the filter paper seeps water within 5 minutes, it is an air filter made of cotton pulp paper (inferior filter paper);
b) If the filter paper seeps water for 2-5 hours, it is made of low-grade wood pulp paper, which can be used, but it will reduce the gas production efficiency of the air compressor (more power consumption and more gas production);
c) If 12-15 water seeps, it belongs to mid-grade filter paper;
d) If no water seeps in within 24 hours, it is a high-grade filter paper.

2. Look at the light to see whether the filter paper is uniform, whether the light transmittance is good, and whether the surface finish of the filter paper is good. It reflects the filtration accuracy and air permeability.

3. Look at the depth and number of folds of the filter paper. If the filter paper is deep and the number of folds of the filter paper is large, it means that the filter area of the air filter is large.

Users in particularly harsh environments are advised to clean the air filter once a day and replace the air filter every 500-800 hours;
Users in a moderate environment clean the air filter every 3-7 days, and replace the air filter every 1000-1500 hours;
Users with a better environment should replace the air filter every 1500-2000 hours.

Hope this article helps you
