How often should you replace fume extraction filters?

How often you need to change your filter depends on the specific application you are using your fume extraction system for. We recommend that filters in use are replaced once every year. Otherwise, you can replace them when the filter indication screen or LED lights state a blockage. Note that this is a guide only, and the condition of each filter depends on the specific application it is being applied to and its level of usage.
