Which of the following practices can help reduce VOC levels in the indoor environment?

Using low-VOC materials is a highly effective practice to reduce volatile organic compound (VOC) levels in indoor environments. VOCs are organic chemicals that can evaporate into the air and may cause various health issues, as well as contribute to poor indoor air quality. By selecting paint, adhesives, cleaning products, and furnishings that are specifically labeled as low in VOC content, individuals can significantly limit the release of these harmful compounds into their homes or workplaces.

Low-VOC materials are designed to emit fewer toxic chemicals, thereby improving the air quality and reducing potential health risks associated with typical high-VOC products. This proactive choice in materials helps create a safer and healthier indoor environment for occupants.

In contrast, while opening windows during winter can improve ventilation, it may not effectively reduce VOCs indoors, especially if outdoor air is also contaminated. Increasing indoor air pressure might help control where air infiltration occurs, but it does not directly address VOC emissions. Using more fabrics in decorations could inadvertently contribute to VOC levels, as many textiles can absorb and later release these compounds into the air. Thus, opting for low-VOC materials stands out as the best practice for reducing indoor VOC levels effectively.
