Good To Know
Q: How often should the generator air filter be replaced? A: Check the air filter every 100 hours or annually, and replace it when visibly dirty or every two years to maintain generator efficiency.
Q: Is this filter washable or reusable? A: No, this is a dry pleated paper filter and should be replaced, not cleaned, when it becomes clogged with dirt or debris.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
