 All right, so that's another one there. Watch what chemicals you keep in your home. Any of those cleaners, make sure you don't have those around. Keep them outside to shed any of that heavy-duty stuff because it will show up in your air quality testing. And sorry, guys, no basement workshops. And ladies, all you people down there working in the basement, if you could take that outside to another building away from the home, you're going to have cleaner indoor air.
