Filter classifications
Airmaster supplies particulate filters which comply with the new filter standard, EN ISO 16890.
EN ISO 16890 use new descriptions which classify the efficiency of the filtration in proportion to the particle size. PM1, PM2,5 and PM10 indicates the particulate matter size in μm. 10 μm is the largest particle and 1 μm is the smallest particle. In front of the PM an e is given (ePM) which indicate the efficiency of the filtration in proportion to the specific particle size and is given in %. For example, a filter which is classified as ePM1
(>55%) capture more than 55% of particle size 1 μm.
The ISO 16890 classifications mentioned are the filter classes we use most. Other filter classes can be supplied on request.
