How long does the filter last?
The life of a filter is determined by the Of the contaminant, the relative humidity and the volume of air cleaned. Unfortunately there is no indicator light on the filter that tells you when it is ready to be replaced. Experience with one Can-Filter will give you an expectation for future Can-Filters in your particularapplication.
