HEPA Filter Testing

HEPA filter testing is important to confirm that they are properly installed with no leaks due to manufacturing defects or installation workmanship.


High Efficiency Particulate Air (HEPA) filters have been used as filtration devices for more than 50 years. Their high efficiency at sub micron particle sizes makes them suitable for applications in areas where cleanroom conditions and contamination control within the rooms are critical.
