How long do CBR Filters and bag prefilters last?
There are many factors that affect the service life of CBR filters, such as local weather conditions, system flow rates, whether the system operates full-time or part-time, and the nature of the threat being protected against. CBR filters may last as long as three years, while bag prefilters typically need replacing at six-month intervals. A surveillance program can help assess filter service life for your installation and operating conditions.
