Preventive fire protection

EN 13501 - The newest standard for preventive fire protection

Air filters may not be the source of a fire, but – as dry textiles often loaded with dust – they can act as accelerant to an event that begins elsewhere. That's why, at European level, filters for air conditioning systems in buildings must be tested in accordance with EN 13501 and meet Class E (normally flammable building materials).

What exactly is EN 13501?

  • The test method is carried out acc. to ISO 11925-2 for Class E
  • It assesses the flammability of a construction product when exposed to a small combustible flame for 15 seconds
  • It tests the dripping behavior and smoke development
  • It provides greater safety for people in the building

Only air filters that conform to this standard and do not increase the fire load of a building may be installed in air conditioning systems in buildings. As smoke is the initial threat to the people, EN 13501 provides greater safety for occupants of a building.

Ensure safety with air filters from MANN+HUMMEL

MANN+HUMMEL air filters conform fully with EN 13501 Class E. That means neither the individual components nor our complete filters increase the fire load of a building – as proven in external fire protection testing in accordance with ISO 11925-2.

But this safety doesn't come at the price of the environment. All of our metal-free filters are fully incinerable to reduce landfill and allow energy to be recovered from their disposal.

Of course, safety is not just about fire protection – especially when dealing with a vital resource such as air. For this reason, air filters must comply with numerous standards that cover various aspects of health and safety.
