The Hepa-Type™ CE 250 filter is a higher grade particulate filter media than the Hepa-Type™ 150 sports and allergy filters. It provides greater efficiency at filtering out sub-micron particulates for a longer period of time. The upgraded filter is part of the protection factor that the CE mask range demands for work applications.
All Respro® filters are inter-changeable, meaning any mask can use any spec filter to achieve the desired filtration. An important point, is that the filter size should match the mask size, i.e. large filter/ large mask.
