The APMS-1516E is an integrated air purifier with high-volume humidification added to powerful air circulation and purification. It can effectively circulate indoor air through its front and top and make indoor spaces more pleasant thanks to its high-volume humidification feature. As this product is large but intended for use in spaces where people live, it was very important that it not only perform well but also blend into interiors. Its intentional stepping design makes it appear smaller. Coway's water droplet form that visualizes the humidification feature in its intake hole pattern is used intelligently to balance product design and performance.
