Purex uses specialized combinations of filter media to capture particles, gases and vapors generated by industrial processes such as laser engraving, laser marking, hand and machine soldering, inkjet printing and many others. Each filter has a unique serial number and is individually tested and certified to ensure performance and safety.

Purex HEPA (High-Efficiency Particulate Air) filter elements are precision manufactured from a pleated material that incorporates reinforcing strips that separate the pleats and help prevent airflow vibration or collapse.

Additionally, air equalization plates are used between the layers of media to further reinforce the filter housing and to distribute the airflow across the filter to ensure all of the filter media is used.
