(2020) indicated that air circulation is generally more effective when devices are elevated, as it allows for better mixing of contaminated and clean air.

Room dimensions: The size of a room determines the intensity of air purifier effectiveness. Units are generally rated for specific areas, so proper height placement can impact their performance. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), an air purifier should ideally be positioned near the height of potential airborne pollutants, often within 3 to 5 feet from the ground, to capture dust and allergens effectively.

Furniture arrangement: The layout of furniture can create barriers to airflow. When the air purifier is placed at a height that is obstructed by large furniture items like sofas or cabinets, it may reduce its efficiency. A study by Chao et al. (2021) found that unobstructed airflow can improve the capture rates of airborne particles by up to 30%. Therefore, the height of the air purifier should be adjusted based on the surrounding furniture to ensure optimal performance.

Type of pollutants: Different pollutants may settle at varying heights. For example, larger particles like dust tend to accumulate on the floor, while smaller particles such as smoke and fine dust can remain suspended in the air. Placing the air purifier too low may capture more floor-level particles, while a higher position may target airborne issues more effectively.
