H11

H11 filters are commonly applied in controlled environments where stable air cleanliness is necessary to protect processes, equipment, or sensitive activities.

They represent a progression within the HEPA range for applications that require more reliable particle control than H10, without the need for higher-grade cleanroom filtration.

Typical Applications

H11 HEPA filters are used in environments that require enhanced air cleanliness and consistent filtration performance.

Common applications include:

• Controlled production and assembly areas

• Electronics manufacturing environments

• Laboratories and testing facilities

• Clean support zones serving cleanrooms

• Technical and process-controlled spaces

In these applications, H11 filters help maintain lower particle concentrations and support stable operating conditions.

Performance Highlights

H11 filters are engineered to deliver consistent HEPA filtration performance under continuous operation.

Key performance characteristics include:

• HEPA filtration tested according to EN 1822

• Higher particle removal efficiency than H10

• Balanced pressure drop suitable for controlled environments

• Stable airflow throughout service life

• Individual filter testing to verify performance

These characteristics make H11 filters suitable for environments where filtration reliability is essential.

FAQ

How does H11 differ from H10 HEPA filtration?

H11 filters provide higher particle removal efficiency than H10 filters, making them better suited for environments that require tighter control of airborne contamination.

Is H11 suitable for cleanroom applications?

H11 filters can be used in clean support areas or less critical cleanroom zones. Higher HEPA grades are typically required for classified cleanrooms.

Can H11 filters be used as a final filtration stage?

In some controlled environments, H11 filters may be used as the final filtration stage. Applications with stricter cleanliness requirements often require H12 or higher grades.

Do H11 HEPA filters require leak testing?

Yes. Under EN 1822, H11 filters are individually tested to verify overall filtration performance and integrity.
