Kipper Your Lungs With a Wood Burner?

One might assume that containing the fuel within a wood burner would reduce the health risks. It has been shown (admittedly, using only 19 stoves in the Sheffield area), however, that opening the door to refuel, floods the room's air with particulates (https://www.theguardian.com/environment/2020/dec/18/wood-burners-triple-harmful-indoor-air-pollution-study-finds). This triples a form of pollution that is known to damage health, especially in the very young and the very old. It was been suggested that the burners (presumably, there are several types?) should carry a health warning!
