Filter Advice Eurovent 4/23

Filter Selection Guideline Eurovent 4/23-2022 based on ISO 16890

Based on the filter standard ISO 16890, Eurovent has developed a guideline for selecting air filters. This is the guideline 4/23-2022.

Outdoor air quality (PMx values in μg/m3)	Supply air classification
	SUP1 (highest) PM2.5 ≤ 1.25 PM10 ≤ 3.75	SUP2 PM2.5 ≤ 2.5 PM10 ≤ 7.5	SUP3 PM2.5 ≤ 3.75 PM10 ≤ 11.25	SUP4 PM2.5 ≤ 5 PM10 ≤ 15	SUP5 (lowest) PM2.5 ≤ 7.5 PM10 ≤ 22.5
	Recommended minimum ISO 16890 filter class
	ePM1	ePM1	ePM2.5	ePM10	ePM10
ODA 1	70%	50%	50%	50%	50%
ODA 2	80%	70%	70%	80%	50%
ODA 3	90%	80%	80%	90%	80%

* Minimum recommended filter efficiency for final filter ISO ePM1-50%
** Minimum recommended filter efficiency for final filter ISO ePM2.5-50%

Tailored Filter Advice

Are you curious about the air quality at your location? We carry out air measurements to assess both indoor and outdoor air quality. We use an advanced particulate matter meter, also known as a Particle Counter. If it turns out that the minimum values for particulate matter are exceeded, we offer solutions to improve indoor air quality. Our advice is based on the guidelines set by the World Health Organization (WHO) for minimum air quality. These guidelines are generally stricter than national regulations.
