In modern industries where air and liquid filtration play a crucial role, ensuring the effectiveness and reliability of filters is non-negotiable. Whether it’s pharmaceuticals, biotechnology, healthcare, food processing, or cleanroom environments, filter integrity testing has become a cornerstone of quality assurance and regulatory compliance. Validair Engineers, a trusted name in environmental validation and calibration, offers Filter Integrity Testing Services designed to verify that filters are installed correctly and functioning as intended — ensuring clean, contaminant-free environments for critical operations.
With years of experience serving regulated sectors across India, Validair Engineers brings expertise, precision, and compliance to every testing project. Their advanced equipment and qualified professionals deliver accurate results that meet global standards such as ISO, GMP, and FDA requirements.
Filter Integrity Testing Service
Filter Integrity Testing is a quality assurance process used to verify the performance of high-efficiency filters such as HEPA and ULPA filters. These filters are critical in controlling airborne contamination in cleanrooms, laboratories, and production facilities. Over time, filters may develop leaks, improper seals, or installation defects that compromise their performance.
Through a series of validated tests, such as aerosol challenge tests (DOP/PAO testing), pressure decay tests, or bubble point tests, the integrity and efficiency of filters are confirmed. This ensures that the filtration system is capable of trapping and retaining harmful particles before they reach sensitive areas.
Validair Engineers’ Filter Integrity Testing Services cover the complete spectrum — from testing new installations to routine periodic validations and troubleshooting performance issues in existing systems.
Why is Filter Integrity Testing Essential?
In controlled environments, even the smallest compromise in filter performance can lead to contamination, product loss, or process failures. Hence, filter integrity testing serves multiple purposes:
- Verification of Installation: After new filters are installed, integrity testing confirms that they are seated and sealed correctly within their housings, preventing any leakage paths.
- Performance Validation: The testing ensures that filters meet their rated efficiency, typically 99.97% for HEPA filters and 99.999% for ULPA filters.
- Regulatory Compliance: Industries governed by GMP, ISO, and FDA standards are required to perform periodic filter integrity tests to maintain certification and operational approval.
- Risk Reduction: By identifying defective filters early, industries prevent cross-contamination and ensure consistent product quality.
- Optimized Maintenance: Routine integrity testing helps schedule filter replacements efficiently, avoiding unnecessary downtime or over-maintenance.

Comprehensive Testing Methods
Validair Engineers employ multiple testing methodologies to evaluate both the installation integrity and operational efficiency of filters. Some of the commonly performed tests include:
- Aerosol Challenge Test (DOP/PAO Test): A controlled aerosol (PAO or DOP) is introduced upstream of the filter, and a photometer measures the downstream concentration. Any leak or damage is detected and precisely located.
- Pressure Decay Test: Used primarily for gas and liquid filtration systems, this method checks pressure loss over time to detect potential leaks or structural weaknesses.
- Bubble Point and Diffusion Testing: These tests assess pore size distribution and integrity of liquid filters, ensuring uniform filtration performance.
- Scan Testing for Installed Filters: This on-site test is performed to identify even minute leaks in installed HEPA filters, ensuring complete system integrity.
- Airflow Visualization (Smoke Test): Conducted alongside integrity tests, it helps visualize airflow patterns to confirm the efficiency of the cleanroom or sterile zone.
Each testing process is documented, analyzed, and validated with detailed reports to assist in audit and compliance documentation.
