If you read the article he says that he covers his nose and mouth, turns on the taps and leaves closing the door. After 20mins he turns them off, closes the door again and waits 20mins for any water vapour to disappear.
I take your point though. If he's so concerned about legionella why doesn't he go the whole hog and wear a mask when he turns the taps on and off.
Still, must be better than taking a shower in it.
