Final answer:
Using materials with low VOC emissions, avoiding formaldehyde-containing products, and improving ventilation can help improve indoor air quality.
Step-by-step explanation:
When it comes to materials that have less off-gassing, there are several options that can improve indoor air quality. One example is using paints and varnishes that have low levels of volatile organic compounds (VOCs). VOCs are chemicals that can slowly release into the air and contribute to indoor air pollution. Another option is using furniture and building materials that are formaldehyde-free. Formaldehyde is a common indoor air pollutant that can be emitted from certain types of wood products and adhesives.
Additionally, choosing flooring materials such as hardwood, tile, or linoleum instead of wall-to-wall carpeting can help reduce off-gassing. Carpeting can trap dust, allergens, and other pollutants that can negatively impact indoor air quality. It's also important to properly ventilate indoor spaces by opening windows or using exhaust fans to bring in fresh air and remove pollutants.
In summary, by selecting materials with low VOC emissions, avoiding formaldehyde-containing products, and improving ventilation, you can create a healthier indoor environment with improved air quality.
