Filter nominal airflow
WebA HEPA filter is specifically designed to target much smaller pollutants and particles that become trapped to fibers. These air filters are normally between 0.5 and 2.0 micrometers. It is important to note that HEPA filters work to capture fine particles but do not filter out gasses and odor molecules. WebThe Eurovent Association has released the fourth edition of the widely-applied Eurovent Recommendation 4/21 – ‘Energy Efficiency Evaluation of air filters for general ventilation purposes’. The updated guidelines set out a new method for the determination of the annual energy consumption for filters operating at an airflow rate other than nominal.
