Used Air Filters in China

The replacement frequency depends on the type of machinery and operating conditions. Typically, air filters should be checked every 50-100 operating hours and replaced if they appear dirty or clogged.

Some air filters are designed to be reusable and can be cleaned with compressed air or washed, while others are disposable. Check the manufacturer's guidelines for specific instructions.

Common signs include reduced engine performance, increased fuel consumption, and visible dirt or damage on the filter. If the engine struggles to start or runs unevenly, the air filter may need attention.
