It's the same with a mass oven. It has several burn chambers that is designed exactly yo burn all smoke. Heck, I even have a portable stove that uses secondary combustion to burn all the wood and smoke. If I ever have to buy a wood stove, I want one which is designed to burn it all. I probably even go all in with a mass oven.
