Hazardous particles

Hazardous particles in the air can be classified according to their size.

Which filter combinations are necessary for which sizes of hazardous particles?

You will find a practice-oriented guide to the filter classes and their specific use with regard to the type of room pollution in our comprehensive view of the different pollutant particle sizes (sizes given in microns; one micron is equivalent to one thousandth of a millimetre).

Select one of the following particle size groups for a detailed description:

• Show coarse-dust particles
• Show PM 10 fine-dust particles
• Show PM 2.5 fine-dust particles
• Show ultra-fine particles
