Residential buildings located in the city center are high-rise buildings, where outdoor air does not flow in. There is therefore an increasing need for air purification. The Healthcare Window detects pollution of indoor air and automatically ventilates the space, without having to open the window. It features rounded corners and seamless connection among parts, thus minimizing the accumulation of dust on the window frame and ensuring easy maintenance. The two modules located in the bottom feature the sound of birds and botanical scent, making the user feel like he is waking up in the woods.
