# Compressed air filter replacement steps and precautions

Compressed air filter after using too long, will lead to too many internal impurities, affecting the gas flow rate, pressure, filtering effect; so the compressed air filter replacement work needs to be carried out regularly.

The general replacement cycle is 1 year, if the user uses a better environment, can be appropriate for a longer period of time, if the use of poor environment, may need to be replaced in about 8 months.
