Formaldehyde
Formaldehyde is a colorless, strong-smelling gas and a common volatile organic compound (VOC) found in many building materials, furnishings, and household products. It can off-gas into indoor air, contributing to irritation of the eyes, nose, and throat and worsening respiratory symptoms for sensitive occupants. Managing formaldehyde levels involves choosing low-emitting materials, improving ventilation, and controlling indoor humidity.
