How to replace Charcoal Filter. The replacement grease and charcoal filters (no tools needed) along with the vent grill fit perfectly. It took less than 5 minutes to replace these parts. I had doubts that parts would be available but Appliance Parts Pros had what I needed. The next time I need appliance parts they will be first on my list.
