Different Ventilation systems:

• Ventilation system where only polluted air is discharged. This system does not supply clean / fresh air. These systems do not have filters.
• A ventilation system where polluted air is discharged and which supplies fresh air. These systems have filters as incoming air needs to be filtered. Deze systemen hebben filters.  

When you’re still not sure which system you have or you might have additional questions please send an email to [email protected]

Clean filters are important for your and the people around you. But also important for maintaining your system. Dirt, bacteria and fungi accumulate in the filters, the system and the air ducts. Over time, the filter becomes saturated and your system has to work harder to get airflow around. This costs more energy and therefore money. 
In addition you don’t want bad bacteria, germs and fungi back in your indoor climate as this is bad for health conditions. 

Filter class is a term used with air filters to display the efficiency of a filter.
