Is it really necessary to clean your microwave grease and charcoal filters?

It's recommended but situational: worth doing for many homes, though skipping it won't usually cause damage on its own.

How often should you clean your microwave grease and charcoal filters?

Quick answer: Every 6 months. Over-the-range models vent through filters that clog with grease. The charcoal filter is what stops recirculated cooking odours.

Why it matters
