Which method is commonly used to improve air quality in air-conditioned environments?

Installing air purifiers in air-conditioned environments is an effective method for improving air quality. Air purifiers are designed to filter out contaminants, allergens, and other harmful particles in the air, such as dust, pollen, smoke, and bacteria. By removing these pollutants, air purifiers help create a cleaner, healthier indoor atmosphere, which is especially important in air-conditioned spaces where air circulation may be limited.

While adding more ductwork can enhance air distribution, it does not specifically address air quality and may not reduce airborne pollutants. Sealing windows has its advantages in terms of energy efficiency and maintaining temperature control, but it can also lead to stale air if there is no fresh air exchange. Increasing the thermostat temperature could save energy, but it does not have a direct impact on enhancing air quality. In contrast, air purifiers actively filter the air, making them a targeted solution to improve indoor air quality in climate-controlled settings.
