As long as you use air fresheners occasionally and according to the instructions on the label, they generally do not pose a significant risk. However, the chemicals in air fresheners can irritate your eyes, skin, and throat. Prolonged use can also cause indoor pollution, sometimes triggering asthma and other lung diseases.
If you have asthma or other lung conditions, or if you are concerned about the chemicals released by air fresheners, you may consider other ways to keep the air fresh, such as keeping the house clean, ensuring proper ventilation, disposing of trash promptly, and repairing leaks in the roof or basement.
