Contaminants come in different forms – generally: aerosols (solids/particles) and gases (gases, vapours). You can choose between the filter types to protect against one of these forms or a combination of both of them.
The table shows you the color coding of filters according to EN14387 – which helps you to determine which filter-type is needed for the contaminants you are dealing with.
