Indoor filter systems assessments
Cleanrooms, utilized in industries like healthcare, pharmaceuticals, and electronics manufacturing, rely heavily on High-Efficiency Particulate Air (HEPA) filters to maintain their stringent cleanliness standards. These filters are subjected to regular tests to ensure optimal function and compliance with regulatory requirements. The tests help in early identification of filter degradation or failure, thereby facilitating timely replacements and maintaining the controlled environment's integrity, crucial for the successful operation of cleanroom activities.
The current state of the art
The Dispersed Oil Particulate (DOP) test, also known as filter integrity testing, is a common method used to evaluate the performance of High-Efficiency Particulate Air (HEPA) filters. This test involves passing oil aerosols through the filter and using sensors to count the particles that penetrate the filter, thereby assessing its integrity and efficiency.
Limitation & Challenges
Accuracy Limitation
DOP may not accurately detect all HEPA-level particulates.
​
​
Size Distribution
Difficulty to achieve precise size distribution of test aerosols.
​
Handling Difficulties
Oil aerosols do not mimic the dry particles and can be hard to handle.
​
Analytics Spheres for filter high precision filter assessment
Analytical Spheres offer an accurate representation of contaminants with well-defined sizes and powdered form for easy application, enabling efficient assessment of filter integrity under various airflow conditions and identification of leaks or inefficiencies in the filtration system.
The advantage of the solution
Accurate representation
Analytical Spheres Closely mimic the typical contaminants that HEPA filters need to remove, ensuring a reliable assessment of filter performance.
Easy Application
​
Analytical Spheres powdered form simplifies the application process, making it more convenient for operators to evaluate filter integrity.​
Visualized Detection
