Apart from its basic function of heating and cooling a HVAC system also does the job of purifying the air. In a commercial building where hundreds of people come and go daily the air gets polluted easily and a HVAC system can remove all these impurities and make the air fresh. Apart from maintaining a constant temperature it also maintains a cleaner air. Many contaminants are present in the air that we may not be able to identify and all these contaminants can be effectively removed with the help of an efficient HVAC system. Where ever a HVAC unit is installed it provides not only a comfortable temperature but also fresh air. These HVAC units have a very efficient filtering system that helps to remove pollutants and keep the air fresh and clean. The air filter in the unit works to pull out all the dust, dirt, mold and other impurities from the air. If such units were not designed with filters then whenever we are in a closed public space then we are most likely to fall sick and those who are allergic would have to seek frequent medical help.
Some filters are designed to pull out even the most tiniest pollutants from the air such heavy duty filters are very beneficial in public spaces as people can be ensured a safe and fresh breathing space. In commercial spaces such filters have to be installed as it can prevent diseases and also give the employees a better working environment.
