Residents of apartment buildings may face various levels of air pollution issues, such as those caused by interior building materials, furnishings, household products, and furniture that contain chemicals, paint, or preservatives.

Since most high-rise buildings or apartment complexes feature shared hallways and ventilation systems, any deficiencies or errors in maintenance or design can contribute to air pollution problems—and in severe cases, may facilitate the spread of airborne pathogens or cross-infection with viruses.

To address these air pollution issues, the most important steps are to eliminate and control the sources of pollution, improve air circulation, and install appropriate air purifiers.

Residents can help eliminate and control sources of pollution by, for example, cleaning and removing household products containing chemicals, and addressing excess moisture or standing water in indoor potted plants that may contribute to mold growth. They should also move furniture or other items blocking ventilation openings out of the way, or occasionally open doors and windows to improve indoor air circulation when outdoor air quality permits.

If residents have implemented the above measures but still find that air pollution problems persist, they should seek solutions and remedies from the relevant property owner or management company.
