FAQs

What filtration standards are compared in this chart?

The document compares the EN779:2012, Eurovent 4/5, and ASHRAE 52.2-2012 filtration classification standards.

What is the relationship between filter class and particle capture efficiency?

Higher filter classes, such as F9, demonstrate significantly greater initial efficiency across smaller particle sizes (0.1 µm to 1.0 µm) compared to lower classes like G1 or G2.

How does the ASHRAE 52.2-2012 rating correspond to European classifications?

The chart maps specific ASHRAE MERV ratings to their corresponding Eurovent and EN779 categories, showing, for example, that M5 filters generally align with MERV 9/10 performance.
