Filter Integrity Test
At SUN CleanAir Systems, Vasai, we understand that when it comes to cleanroom environments—where pharmaceuticals, electronics, biotechnology, and food processing rely on sterile and particle-free conditions—air filtration performance is mission-critical. One of the most essential services we provide is the Filter Integrity Test, an indispensable validation method for ensuring your HEPA and ULPA filters are functioning at optimal efficiency.
What is a Filter Integrity Test?
A Filter Integrity Test, also known as a DOP Test (Dispersed Oil Particulate Test), is a method used to verify the effectiveness of high-efficiency particulate air (HEPA) and ultra-low particulate air (ULPA) filters. This non-destructive test checks for filter media leaks, gasket leaks, and frame integrity to ensure that the air entering your cleanroom is thoroughly filtered and contaminant-free.
Why is it Important?
Filter leaks, even microscopic ones, can compromise the sterility and performance of cleanroom operations. An undetected leak may lead to costly product contamination, regulatory violations, or compromised patient safety. Filter Integrity Testing:
- Validates compliance with ISO 14644-1, GMP, and FDA standards
- Ensures reliable contamination control
- Helps maintain product safety and quality
- Is crucial for audits and quality assurance
Our Testing Process at SUN CleanAir Systems
Our highly trained technicians follow industry best practices, including:
- Aerosol Challenge : A challenge aerosol (usually PAO or DOP) is introduced upstream of the filter.
- Scanning Probe Method : A photometer or aerosol particle counter is used to scan the filter face and housing perimeter.
- Leak Detection : Any leakage point above the acceptable threshold (typically 0.01% for HEPA filters) is identified.
- Detailed Report : A comprehensive test certificate is issued, including filter ID, leak locations, challenge concentration, and pass/fail status.
