3M Particulate Filter for Adflo 837010

Particulate filter replacement. Replace it when the particle filter indicator turns red. Otherwise, replace whenever the battery run time becomes too short or when the filter becomes completely full and triggers the low airflow alarm. Important: The Adflo particulate filter cannot be cleaned. Do not attempt to remove contaminants using a compressed air line, as this will impair filter performance and automatically void the respirator warranty.
