H12
H12 HEPA filters are designed for applications that require a high level of particle control and filtration reliability.
Under the EN 1822 standard, H12 filters provide significantly improved efficiency compared to lower HEPA grades, supporting environments where airborne contamination must be tightly managed.
H12 filters are commonly used in advanced controlled environments where process stability and consistent air cleanliness are essential.
They represent a key step toward cleanroom-grade filtration while maintaining compatibility with engineered air handling systems.
This grade is often selected when system designers require a higher safety margin than H11, but do not yet require the most widely specified cleanroom HEPA grades.
Typical Applications
H12 HEPA filters are applied in environments with strict requirements for air cleanliness and operational stability.
Common applications include:
-
Advanced electronics manufacturing areas
-
Battery production support environments
-
Precision assembly and process zones
-
Research laboratories and technical facilities
-
Clean support areas upstream of cleanrooms
In these applications, H12 filters help reduce airborne particle concentrations and support consistent process conditions.
Performance Highlights
H12 filters are engineered to deliver reliable HEPA filtration performance under demanding operating conditions.
Key performance characteristics include:
-
HEPA filtration tested according to EN 1822
-
Higher overall efficiency compared to H11
-
Stable pressure drop suitable for engineered systems
-
Consistent airflow throughout service life
-
Individual filter testing to verify integrity and performance
These characteristics make H12 filters suitable for environments where filtration performance must be predictable and dependable.
FAQ
How does H12 differ from H11 HEPA filtration?
H12 filters provide higher filtration efficiency than H11 filters and are used in environments where tighter airborne particle control and higher reliability are required.
Is H12 suitable for cleanroom applications?
H12 filters can be used in clean support areas and certain cleanroom-related applications. Fully classified cleanrooms typically require higher HEPA grades such as H13 or H14.
Can H12 filters be used as a final filtration stage?
In some advanced controlled environments, H12 filters may be used as the final filtration stage. Cleanroom environments generally require higher HEPA grades.
Do H12 HEPA filters require individual testing?
Yes. Under EN 1822, H12 filters are individually tested to verify filtration efficiency and filter integrity.
