U15

Compared to H14 HEPA filters, U15 filters provide a significantly higher level of particle removal, making them suitable for advanced cleanroom applications that demand extremely low airborne particle concentrations.

U15 filters are typically selected when HEPA filtration no longer provides sufficient control and when processes require the additional safety margin offered by ULPA technology.

Typical Applications

U15 ULPA filters are applied in cleanroom environments with ultra-stringent air cleanliness requirements.

Common applications include:

• Advanced semiconductor manufacturing areas

• Precision electronics and microfabrication facilities

• Nanotechnology and materials research cleanrooms

• High-sensitivity optical and photonics production

• Critical zones within leading-edge manufacturing environments

In these applications, U15 filters support ultra-clean conditions and help maintain process consistency.

Performance Highlights

U15 filters are engineered to deliver ultra-high filtration performance while maintaining stable airflow in engineered cleanroom systems.

Key performance characteristics include:

• ULPA filtration tested according to EN 1822

• Extremely high particle removal efficiency beyond HEPA levels

• Mandatory individual efficiency and leak testing

• Stable pressure drop suitable for advanced cleanroom designs

• Reliable performance under continuous operation

These characteristics make U15 filters suitable for applications entering the ULPA filtration range.

FAQ

How does U15 differ from H14 HEPA filtration?

U15 filters provide significantly higher particle removal efficiency than H14 HEPA filters and are classified as ULPA filters under EN 1822, making them suitable for more demanding cleanroom applications.

Are U15 filters required in most cleanrooms?

No. U15 filters are typically used only in advanced cleanroom environments where HEPA filtration does not provide sufficient contamination control.

Can U15 filters be used as the final filtration stage?

Yes. U15 filters are commonly used as the final filtration stage in ultra-clean environments where maximum particle control is required.

Do U15 ULPA filters require individual testing?

Yes. Under EN 1822, U15 filters undergo individual efficiency testing and comprehensive leak scanning to verify performance and integrity.
