How Often Should I Replace The primary air filter?

When deciding how often to replace a primary air filter, several key factors need to be considered. Here are some suggestions for the replacement cycle of primary air filters for your reference:

1. General replacement cycle:

  - For primary air filters, it is usually recommended to replace them every 3 months. This recommendation is based on typical usage environments and air quality.

2. Usage environment:

  - If the air quality in your environment is poor, such as in heavily polluted areas, or in environments with a lot of dust, dander, pollen, and other particles, you may need to replace the primary air filter more frequently.

3. Other considerations:

  - When replacing the primary air filter, make sure to choose a model and specifications that are compatible with your equipment.

In conclusion, the replacement cycle of primary air filters depends mainly on the usage environment, filter characteristics, and the results of regular inspections. In heavily polluted environments or when the filter shows signs of quick dirt accumulation during use, it is advisable to replace the primary air filter more frequently to ensure the proper functioning of the equipment and the cleanliness of the air.
