- A centerpiece adds elegance and beauty to any table setting. But a correct centerpiece should be low so people at the table can see each other. The correct air freshener? Glade. (rain pattering) Glade is always light and delicate. Some air fresheners mask odors with a strong scent of their own, but Glade is lightly scented. It cleans and freshens the air like a spring shower. As far as I'm concerned, Glade is the only air freshener to use.
