H14

They are designed for environments where airborne contamination presents a significant risk to product quality, process integrity, or regulatory compliance.

H14 filters provide an additional safety margin beyond standard cleanroom filtration. They are selected when the tolerance for particle penetration is extremely low and when maximum control of airborne contamination is required within the HEPA filtration range.

This grade is typically specified for critical cleanroom applications where failure or deviation could result in serious operational or compliance consequences.

Typical Applications

H14 HEPA filters are used in cleanroom environments with the most stringent cleanliness requirements within the HEPA category.

Common applications include:

• High-grade pharmaceutical production and filling areas

• Advanced semiconductor and microelectronics cleanrooms

• Sterile manufacturing and packaging environments

• High-risk research and laboratory cleanrooms

• Critical zones within battery and precision manufacturing facilities

In these applications, H14 filters help ensure maximum airborne particle control and environmental stability.

Performance Highlights

H14 filters are engineered to deliver the highest HEPA filtration performance defined by EN 1822.

Key performance characteristics include:

• HEPA filtration tested according to EN 1822

• Extremely high overall and local filtration efficiency

• Mandatory individual leak testing across the filter face

• Stable pressure drop suitable for critical cleanroom airflow design

• Reliable performance throughout the filter service life

These characteristics make H14 filters suitable for applications where risk mitigation and process protection are paramount.

FAQ

When is H14 required instead of H13 HEPA filtration?

H14 filters are required when cleanroom applications involve higher risk, stricter regulatory control, or extremely low tolerance for airborne contamination compared to standard cleanroom environments.

Does H14 significantly increase system resistance compared to H13?

H14 filters typically have a higher pressure drop than H13 filters. System airflow capacity and fan selection must be considered during design and filter replacement.

Are H14 filters suitable for all cleanroom classes?

H14 filters are suitable for high-grade cleanrooms. The required HEPA grade should always be determined based on cleanroom classification, process sensitivity, and applicable regulations.

Do H14 HEPA filters require additional testing?

Yes. Under EN 1822, H14 filters undergo individual efficiency testing and comprehensive leak scanning to verify performance and integrity.
