EUROVENT 4/23 - CHOOSING THE RIGHT AIR FILTER
How should you decide on the correct filter choice for a facility? In Europe, the Eurovent 4/23 standard helps people easily choose the right air filter based on two key parameters: the outdoor air value (based on WHO guidelines), and the type of building or activities done in the building. Eurovent 4/23 provides recommendations on the minimum air filtration level for buildings to help protect their occupants against harmful airborne contaminants.
