HEPA Filter Testing
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.
WHEN SHOULD HEPA FILTERS BE TESTED?
- On site, prior to use.
- After any electrical or mechanical maintenance.
- After filter replacement.
- After re-location of work stations or safety cabinets.
- At least annually.
- As required by the organization’s GMP code or regulatory authority.
- In special circumstances, such as a significant change in the work program, or where impaired operation is suspected.
WHY TEST HEPA FILTERS?
HEPA filter testing is important to verify they are installed correctly without leaks due to manufacturing defects or installation workmanship. HEPA filters may begin leaking after a period of time or if the filter becomes loaded. Periodical checks for integrity and pressure drops will significantly reduce the chance of leakage.
AG&G Services is accredited to perform this test either with DPC or DOP methods, following AS/ISO 14644.3(2009) and AS 1807.6-7 (2000) standards.
