Which method is recommended for reducing indoor air pollutants?

Using air purifiers and maintaining HVAC systems is a highly effective method for reducing indoor air pollutants. Air purifiers are designed to capture and remove contaminants from the air, including dust, allergens, pet dander, and smoke. This can significantly improve the overall air quality in a space, particularly in areas with higher concentrations of pollutants.

Moreover, maintaining HVAC systems is crucial as these systems also play a key role in filtering and circulating air throughout a building. Regular maintenance, including changing filters and ensuring proper ventilation, helps to prevent the buildup of pollutants and improves the system's efficiency. By optimizing air flow and filtration, HVAC systems can contribute to a healthier indoor environment.

In contrast, installing additional carpeting or increasing indoor humidity can potentially exacerbate air quality issues. Carpeting can trap dust and allergens, while high humidity can promote mold growth. Using more toxic cleaning agents is detrimental to indoor air quality, as these substances can release harmful chemicals into the air, contributing to various health problems. Thus, the recommended approach focuses on enhancing air purification and ventilation to create a healthier indoor environment.
