Answer

Occasional exposure to air fresheners isn't likely to cause problems, as long as the products are used as directed. However, the chemicals in air fresheners may irritate your eyes, skin and throat. And long-term use of air fresheners may contribute to indoor pollution, which can sometimes trigger asthma and other lung problems. If you choose to use continuous air fresheners, carefully follow the package directions. If you have asthma or other lung problems or you're simply concerned about the chemicals emitted by air fresheners, consider other options to freshen the air in your home. Keep your home clean, and make sure your home is properly ventilated. Sprinkle baking soda in the bottom of your wastebaskets. Grind fresh lemon slices in the garbage disposal. Take out the trash promptly. Repair any leaks in the roof or basement.
