HEPA & ULPA Filters

Understanding HEPA Class H14 and ULPA Filtration Standards

When selecting a cleanroom filter, understanding the EN 1822 1 standard is crucial. A standard HEPA filter class H14 offers 99.995% efficiency, ideal for laminar flow HEPA filter systems and HEPA filter microbiology applications. For demanding semiconductor facilities, an ULPA filter U15 or higher is strictly required.

Whether you are sourcing a mini pleat HEPA, a zero-leakage gel seal HEPA filter, or a high temperature HEPA filter for industrial ovens, matching the precise media to your HVAC HEPA filters system ensures absolute compliance and significant energy savings.
