What can often be a source of indoor air pollutants?

Household cleaning agents are recognized as a common source of indoor air pollutants due to the volatile organic compounds (VOCs) and other chemicals they contain. When these substances are used for cleaning, they can release gases that contribute to indoor air quality issues. Chemicals in cleaners can include solvents, fragrances, and other irritants that can lead to respiratory problems, allergic reactions, and overall discomfort in indoor environments.

In contrast, outdoor air filters are designed to improve air quality by removing pollutants from outdoor air before they enter a building, thus reducing indoor pollutant levels. Natural light typically enhances indoor environments and can even help reduce the need for artificial lighting, reducing energy consumption without negatively affecting air quality. Well-ventilated spaces promote air circulation and can help dilute indoor air pollutants, contributing to a healthier indoor environment.
