What is the Effect of Air Filters on HVAC?

HVAC stands for Heating and Ventilating Air Conditioner. They help in regulating the temperature of your room and provide you cold or hot air depending on the season. They help in providing high quality, clean and healthy air. The major part of cleaning the air is bagged by the air filters, and this is where their role comes into play. As soon as the air enters the HVAC system, filters catch all the dust, soiled particles and prohibits them from entering the system. The entire process of filtration only works when the HVAC unit fan is in operating condition.

A filter that is unclean should be changed or cleaned as per the need. In other words, you can even say that it can clog the air and restrict it from moving from the grill, forcing the system to use more energy to work efficiently and add up to your energy bill. Most of the cooling and heating failures occur because of the incapability to sustain the filtration system. Dirt, dust, and mud may enter the air ducts as the filters have been blocked and then spread in your house.

Soiled filters are also responsible for affecting the efficiency of the HVAC system. They create trouble for maintaining the optimum temperature inside the room. This results in overheating the furnace that eventually turns off the furnace due to which a condition of  “operating excessive restrict” reaches.

There are a lot of varieties of HVAC systems available on the market. However there are four main types:

• Electrostatic Filters: They are useful to restrict the mud particles from entering the HVAC system. The best part of installing them is that they can be reused and reinstalled by simply cleaning by a vacuum cleaner and washing with water once in every thirty days.

• Pleated Filters: They come with an extra floor space for the filters. It is important to replace them every time a mud storm comes or if your HVAC system is placed in a windy atmosphere. Many of this type of filters are cheap and can be easily disposed of.

• HEPA Filters: They are specifically designed in a way that they reduce the risk of Bronchial Asthma and other allergic reactions that people in the house may suffer from if the air is not filtered properly.

• Activated Carbon Filters: They extract all the chemical fumes and odors along with the dust particles. They find its use in the areas that have many chemical factories in the surroundings.
