Nowadays, many people spend most of their time in indoor environments. Since central air conditioning systems in public living spaces circulate the air by recirculation method, particles transferred to the ambient air by actions such as sneezing, coughing, speaking and breathing spread in the air and increase the risk of infecting people through the respiratory tract. For this reason, it is important for health to support public living spaces with clean air and to clean the indoor air polluted by human breath hygienically with correct methods.

Healthy clean air and energy savings are achieved thanks to correct project design with NAF Filter products in air conditioning systems used to create air conditions suitable for the indoor environment (humidity control depending on heating-cooling application).
