EN 1822 Standard. Absolute Filters (EPA, HEPA and ULPA)<\/h2>\n

Filter Classification<\/h3>\n

To HEPA and ULPA Filters, the classification is based on Eurovent 4\/4 standard which defines 5 types of Filters: EU 10, EU 11, EU 12, EU 13 and EU 14.<\/p>\n

In order to cope with the demands of high technology, there is a need for new testing methods and a new classification of absolute filters<\/p>\n

DIN launched in Germany for HEPA and ULPA filters the project DIN 24183, based on particles measurements, CEN accepted as a basic principle system of testing and rating<\/p>\n

EN 1822. European standard EN 1822, replaces several national standards such as DIN 24184, BS 3928 and AFNOR 44013.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

*\u00a0Comprehensive Efficiency is the average value of all local efficiencies in the front area of the filter<\/span><\/p>\n

In the first stage of this standard EN 1822, the fractional yield for different filtering measures will be assessed at the same rate in the filter. The purpose is to determine the particle size for which the filter material offers the lowest retention efficiency, this size is called: Most Penetrating Particle Size (MPPS)<\/p>\n

<\/div>\n
<\/div>\n

The particle size is usually between 0.15 and 0.25<\/p>\n

The next step is to know the collection efficiency of the filter for this MPPS<\/p>\n

Depending on the performance, leakage and porosity are classified into two groups:<\/p>\n

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 HEPA (High Efficiency Particulate Air): E10, E11, E12, H13 and H14<\/p>\n

\u00b7\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 ULPA filters (Ultra Low Penetration Air)<\/p>\n
