What is the expected life of the unit charcoal vent stack filter?
The activated charcoal can only absorb so much hydrogen sulfide, the gas that causes the smell. The filters will last between 1 and 5 years, possibly longer, depending on your septic system. For example, if you put them on a restaurant they may last 2 years. If you put them on a residence they may last 5 or more years. If you use a lot of bleach in your laundry or if you have a water softener they may not last as long.
