Inside the hood is a filter, now I understand that cleanliness may be new to you but if the filter is clogged up with fat already then it won't filter the air and effectively make the whole thing a little pointless
Perhaps stick with something you know about when replying.
Woah mister grouchy pants, have a look a before you start shooting from the hip homie and make yourself look like a complete idiot. There are two type of hood filters, Fabric and metal mesh, Einstein.
Maybe doo dumb to read, maybe pictures will help.
I'll update you when sesame street make a video about this, if this one was too much for you to take in.
Now lets think about this a little harder. Why would I ask about a filter for a head, if it was metal. Wouldn't you think that I could work it out that I just wiped it.
A filter is a filter, a metal grill is a metal grill Mister Numb Nuts but I do thank you for your considerable help in this matter.
