What is the best control measure for formaldehyde air pollution in the home?

The best control measure for formaldehyde air pollution in the home is to implement a combination of strategies, which is why selecting all options as part of the solution is appropriate.

Avoidance of formaldehyde-containing products is crucial because it prevents the introduction of this harmful chemical into the indoor environment. Common sources of formaldehyde include certain adhesives, particleboard, plywood, and some types of insulation, so conscious purchasing can significantly reduce exposure.

Coating and sealing materials that contain formaldehyde is another effective strategy. By applying a sealant, the release of formaldehyde into the air can be minimized. This method can effectively reduce off-gassing, making enclosed spaces safer for occupants.

Increasing the amount of outside air is also beneficial because improved ventilation helps to dilute any pollutants present in the indoor air, including formaldehyde. Properly ventilated spaces can significantly decrease the concentration of airborne formaldehyde, thus improving overall air quality.

By using all these strategies collectively, homeowners can more effectively manage and mitigate formaldehyde levels in their homes, making "all of the above" the most comprehensive and effective approach to controlling this air pollutant.
