EN to ASHRAE

The ASHRAE (The American Society of Heating, Refrigeration and Air-Conditioning Engineers) 52.2 standard rates air filters with a MERV (Minimum Efficiency Reporting Value) classification which can be compared to the EN standards, although it's important to note that the test specification is slightly different so the end result is an estimate.

As ASHRAE 52.2 does not include an initial/discharged efficiency test requirement it can only be compared to EN779:2002.

To compare EN779:2012 to ASHRAE 52.2, the EN779:2002 result must be established first. Please contact us or see EN779:2002 to EN779:2012 for further explanation.
