Replace the Industrial Air Filters By Yourself-Easy & Budget Friendly

Air filtration systems in cleanrooms can effectively prevent external dust particles from entering, improving the safety and efficiency of the production environment. However, as consumables, the air filters in the filtration system need to be replaced regularly. Generally, it is recommended to replace pre-filters every 2-3 months, medium-efficiency filters every 6 months, and HEPA/ULPA filters every 1-2 years.

First, we'd like to state that although replacing air filters is not difficult technologically, we still recommend that a professional be present during the replacement to avoid significant financial losses due to incorrect installation (especially in large cleanrooms). If you plan to replace them yourself, here are some steps and suggestions to help you successfully install and commission the filters.

Step 1: Order the Correct Air Filters

Depending on the specific needs of different cleanrooms, the filters in the filtration system will vary. Before replacing the filters, you need to confirm the model and specifications of the filters. You can refer to the equipment manual or consult the supplier to ensure that the purchased filters meet the requirements of the cleanroom.

Step 2: Proper Removal and Disposal of the Used Air Filters

Before removing the used filters, ensure the cleanroom environment is as stable as possible. When removing the filters, take care not to release dust into the air. After removal, place it in a sealed bag to prevent contaminant escape and then dispose of it according to local environmental regulations.

Step 3: Proper Air Filter Installation

When installing the new filters, ensure you follow the manufacturer's instructions. The filters usually have airflow direction markings; insert it according to the arrows and ensure it is securely fastened. Check the seal between the filter and the frame to ensure there are no gaps to prevent airflow short-circuiting. If necessary, use the provided securing devices for reinforcement. Handle fiberglass filters with care during installation to avoid damaging the filter media.

Step 4: Testing the New Air Filter

Once the air filters installed, start to observe the air quality level and ensure the new filters effectively capture airborne particles. Monitor system pressure and flow rate to ensure they are within normal ranges. If any abnormalities are detected, investigate the cause promptly.

Regularly replacing air filters in cleanrooms is crucial for ensuring indoor air quality and safe production. Following the steps outlined above, you can smoothly replace the filters. However, it is recommended that a professional be present during the replacement process to ensure proper installation and adjustment, thereby minimizing potential economic losses. Maintaining a professional and meticulous approach will help ensure the efficient operation of the cleanroom.
