Air freshener

Hi, ladies. I have a question. We currently have no water at our house, so I'm staying the day with a friend of my husband's. He uses plug in air fresheners but because the smell bothers me, he unplugged them before I came over. It still smells in here though. I know air fresheners aren't good during pregnancy, but should I be worried of I'm over here for less than a full day and they're not actually plugged in? Sorry if that's a silly question.
