- No tools, a few minutes: 5 steps, listed on this page with the replacement video where the maker has one.
- What happens if I don't change it?
- Grease builds up in the mesh and the fan pulls less air, so smoke and smells linger; a recirculating hood with a spent carbon filter blows the smell back into the kitchen.
- How do I reset the filter light?
- Most hoods this part fits have no filter reminder. If yours has a filter light, the manual for your model explains the reset.
