ASME BPE, or the American Society of Mechanical Engineers Bioprocessing Equipment standard, was introduced in 1997 to address challenges in biopharmaceutical manufacturing, particularly around equipment cleanliness and process consistency. This standard sets the requirements for the design, fabrication, and testing of bioprocessing equipment to ensure hygiene and reliability.
The standard is widely used across industries that require high levels of sanitation and product integrity, such as:
- Biopharmaceuticals
- Pharmaceuticals (including API and cosmetic production)
- Food and beverage
ASME BPE is regularly updated to reflect advancements in materials and manufacturing techniques, ensuring that it remains relevant and effective in modern production environments.
ASME BPE and Process Filter Housings
Manufacturers produce a wide range of ASME BPE-compliant filter housings designed for hygienic applications. While these housings are more expensive than standard or basic hygienic options, they offer enhanced durability, cleanliness, and compliance with strict industry standards. The higher cost comes from the use of premium materials, advanced fabrication methods, and specialized welding procedures.

What Makes a Filter Housing Hygienic?
A hygienic filter housing is designed to prevent contamination, facilitate cleaning, and maintain product integrity. Here are the key factors that define a hygienic design:
1. Design Features
Hygienic filter housings typically include:
- Sanitary body closures and couplings
- Sloped surfaces to promote complete drainage
- In-situ cleanable components
- A wetted surface finish of SF4 (0.38 Ra), which is smoother than standard hygienic finishes (0.4–0.8 Ra)
2. Construction Materials
Materials must be suitable for the intended application to reduce the risk of corrosion, stress cracking, and contamination. For example, 1.4435 stainless steel is commonly used for its resistance to high-purity water and steam. In more aggressive environments, such as those involving concentrated solvents, nickel-based alloys like Alloy 22 offer superior corrosion resistance.
Elastomeric seals and O-rings must also meet regulatory approvals, such as FDA 21CFR 177 and USP Class VI.
3. Material Certification and Traceability
All BPE-compliant housings should have documentation linking wetted and pressure-retaining parts to their original mill certificates. Clear identification marks are essential for traceability and quality assurance.
4. Fabrication
Proper welding is crucial for maintaining corrosion resistance. For example, 1.4435 stainless steel requires tight control over ferrite levels in heat-affected zones (<3%). This often necessitates new weld procedures, third-party approvals, and skilled welders.
Housings should allow for automated welding where possible, and all welds should be fully ground to achieve the required surface finish.
It’s All About Risk
BPE-compliant housings come with additional costs due to stricter material requirements, detailed documentation, and rigorous testing. On average, BPE-compliant housings can be at least 50% more expensive than standard pharmaceutical-grade housings.
But the investment may be justified by the reduced risk of contamination from corrosion or inadequate cleaning between batches. At Amazon Filters, we offer a range of single-stack filter housings that meet ASME BPE standards. Depending on your process, it may be more practical to apply only certain aspects of the BPE standard to balance cost and performance.
