To effectively reduce airborne particles, what device could be used?

To effectively reduce airborne particles, using an air filtration device is highly beneficial. These devices are specifically designed to capture and remove particles from the air, such as dust, pollen, mold spores, and other allergens. By utilizing filters, particularly high-efficiency particulate air (HEPA) filters in many air filtration systems, they can significantly improve air quality by trapping small particles that might otherwise remain suspended in the air.

Air conditioning units and dehumidifiers can help manage certain environmental conditions, such as temperature and humidity, respectively; however, they do not primarily serve the role of filtering out airborne pollutants. An air conditioning unit can recirculate air but may not efficiently remove particles without a dedicated filtration system. A dehumidifier, while important for controlling moisture levels, does not filter air in the same manner as an air filtration device.

On the other hand, a humidifier adds moisture to the air but does not address airborne particles; in fact, if not maintained properly, it could introduce additional contaminants, such as mold. Therefore, when the goal is to specifically target and reduce airborne particles, an air filtration device is the most effective choice.
