An integrity-test pass alone does not guarantee finished-product sterility. Review the downstream boundary and process validation.

Sterilizing filtration and the aseptic receiver
Fluid
Scroll horizontally to see the complete flow.
Product- and process-specific validation and integrity control before and after use are required. Validate retention and integrity of the sterilizing-grade membrane and control downstream contamination. Nominal pore size alone does not establish suitability for sterilizing filtration.
These conceptual views explain flow direction. Actual piping, wiring and physical flow rates require a separate design.
01 — PROCESS
Where does each step fit?
Define the intended use and conditions to identify the required role of each item.
Validate the filter and process
Verify retention performance, compatibility, recovery, and integrity acceptance criteria.
Manage production batches
Control the process through established filtration and test procedures and batch records.
02 — SELECTION
What should be selected and verified?
For sterilizing-grade filters, microbial retention validation must be linked to integrity acceptance criteria. Review chemical compatibility with the product, extractables and leachables, adsorption, capacity, and sterilization conditions together.
Scroll horizontally to review all columns.
| Process objective | Step to review | Selection evidence |
|---|---|---|
| Microbial retention | Product- and process-specific validation | Challenge organism, actual product or a justified surrogate fluid, and worst-case conditions |
| Product quality | Adsorption, aggregation, and E&L | Protein and surfactant recovery and quality attributes |
| Processing capacity | Filtration tests with representative feed | Concentration, viscosity, flux, maximum differential pressure, and batch processing time |
| Integrity management | Validated test methods | Plans for post-sterilization pre-use testing, post-use testing, and failure investigations |
These examples start the application review. Pore size or nominal rating alone does not establish suitability or retention; confirm with the actual process fluid and supplier evidence.
03 — OPERATING CHECKS
Use operating data to identify improvements.
Confirm the link between test specifications
Verify that integrity test limits correlate with the microbial retention performance of the filter concerned.
Reflect product-specific worst-case conditions
Do not size filter area for a highly concentrated product using only the high flow rates achieved with water or diluted solutions.
Review the entire system
Address maintenance of sterility in downstream piping, connections, and filling operations together with the contamination control strategy.
04 — QUESTIONS
Frequently asked questions
Does a 0.22 µm label mean the filter is sterilizing-grade?
Do not judge by the pore size label alone. Review the manufacturer’s retention validation, integrity correlation data, and process-specific validation.
How should pre-use integrity testing be defined?
Plan post-sterilization pre-use testing in line with the applicable regulations and contamination control strategy. Where performing the test is difficult, the quality department must assess the justification against the relevant requirements.
05 — APPLICATION REVIEW
Prepare the conditions for a technical discussion.
These details help narrow the configuration and the evidence to review.
- Product composition, concentration, and maximum viscosity
- Batch volume and maximum filtration time
- Pressure, temperature, and sterilization conditions
- Existing filter validation data and test criteria
- Product quality and recovery criteria
