Help with smelly cooking!

So, my daughter’s boyfriend spends a LOT of time in the kitchen cooking, and I mean a LOT. Not every day, but hours at a time. He is Jamaican and cooks food that is very spicy and very very strong in odor. My clothes are smelling and the smells honestly make me get a plugged nose, and my eyes water. Have tried running an air purifier and I’ve asked him to use the vent fan but it’s pretty tough to get it cleared out. Thoughts PLEASE.
