Volatile organic compounds are gases released by many indoor materials and products, such as paints, solvents, adhesives, and cleaners. Reducing indoor VOCs works best when you choose low-emission or VOC-free materials, cutting the source of these contaminants. Improving ventilation adds outdoor air to the room, diluting the concentration of any VOCs that remain and helping remove them more quickly. This combination directly lowers the amount of VOCs people are exposed to indoors, which is why it’s the typical strategy for improving indoor air quality in this context.

For context, other indoor pollutants are controlled in different ways: noise is a sound issue, radon is usually addressed with sealing and specific mitigation systems, and particulate matter is mainly tackled through filtration and reducing indoor emission sources, rather than relying primarily on ventilation and low-emission materials.
