Filter Life Cycle Depends upon Application
The life cycle of a filter depends upon how long it is used under the conditions of a specific
application.
Application Specialists at Sentry Air can help you determine a filter-replacement schedule, but
the final decision should be made with the recommendation of your local safety expert and/or
industrial hygiene professional. Contact your SAS specialist to find out about optional
equipment.
