The best approach to control formaldehyde air pollution in the home is which of the following?

To effectively control formaldehyde air pollution in the home, a comprehensive approach that encompasses multiple strategies is essential. Each of the methods listed contributes to reducing exposure and improving indoor air quality.

Avoidance of formaldehyde-containing products is critical because many household items, such as certain adhesives, pressed wood products, and some textiles, can emit formaldehyde over time. By choosing alternatives that do not contain this chemical, residents can significantly lessen its presence in their living spaces.

Coating and sealing materials that contain formaldehyde is another effective strategy. This approach involves applying sealants or coatings that can trap the formaldehyde vapors within the materials, thus decreasing its release into the air. This method is particularly useful for existing items in the home that cannot be easily replaced or removed.

Increasing the amount of outside air can further dilute indoor pollutants, including formaldehyde. By improving ventilation, either naturally through open windows or mechanically with air exchange systems, the concentration of formaldehyde in the indoor environment can be reduced, leading to improved air quality and lower health risks.

Therefore, utilizing all of these strategies together offers the most comprehensive solution for controlling formaldehyde air pollution, making the choice that includes all strategies the most effective course of action.
