Standard-HEPA Filter Standard ISO 29463 VS EN 1822
ISO 29463 originates from EN1822, which defines EPA, HEPA and ULPA filters commonly used in industry. While ISO 29463 maintains the classification of EPA, HEPA and ULPA.But replace E10-E12, H13-H14 and U15-U17 with the following 13 filter levels. The ISO 29463 can't replace EN 1822, EN 1822 will continue to be valid.

Testing and classification method for filters with MPPS <0.1 um (e.g. membrane medium filters)——Understanding ISO 29463 and Testing Requirements
In light of these considerations, a 0.1 μm particle counter is generally sufficient for most industrial applications. While it may not detect the smallest particles required for precise MPPS measurement in membrane filters, the alternative procedure outlined in ISO 29463 ensures that accurate and reliable filtration efficiency can still be determined. The SC-FT-1406DU, with its high efficiency range, further supports these testing needs, balancing the need for practical solutions with the technical limitations of available particle detection technology.
