Air filters are a critical component of your HVAC system. They trap airborne particles and other contaminants in the air and prevent them from entering your home or business, keeping you and your family safe from allergies and other harmful effects. However, air filters have a limited lifespan and should be changed regularly to ensure optimal performance and indoor air quality. The specific timing of when to change your air filter will depend on many factors, including your location, home or business type, and HVAC system. The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) recommends changing your air filter at least once every 30 days for best results. The following guidelines will help you determine when it’s time for a new filter in your HVAC system at home or office.

What are air filters and why do we need them?

Air filters are generally made of a combination of materials such as polyester, fiberglass, or coconut husks. They trap microscopic contaminants such as dust, pollen, and pet dander that can trigger allergies and infections in sensitive individuals. Air filters trap these harmful particles and prevent them from entering your home or business. They are a crucial part of your HVAC system.Air filters trap contaminants in the air and prevent them from entering your home or business. They are a critical part of your HVAC system. Air filters trap harmful particles in the air and prevent them from entering your home or business. They are responsible for maintaining the quality of indoor air by removing dirt, dust, and other contaminants. Air filters trap these harmful particles and prevent them from entering your home or business. There are three different types of HVAC systems: HVAC refers to heating, ventilation, and air conditioning, which is the process of regulating indoor temperature by altering the flow of air in a building. HVAC systems are used to control indoor temperature and humidity to provide a comfortable living environment.

How often should you change your air filter?

The frequency with which you should change your air filter will depend on your specific climate, home or business type, and HVAC system. Generally, you should change your air filter every 30 days to maintain optimal performance. However, this may vary depending on your specific situation. For example, if you live in a very dusty area, you may need to clean your air filter more often. Air filters must be replaced frequently to ensure optimal performance.

HVAC systems are used to control indoor temperature and humidity to provide a comfortable living environment. Air filters trap harmful particles in the air and prevent them from entering your home or business. There are three different types of HVAC systems:

  • Central air systems: In a central air system, the air filter is typically located at the air handler, which is the main component of the HVAC system. This filter traps all contaminants in the air, including pet dander, dust, and mold spores. They should be changed every 30 to 60 days.

  • Room air conditioner: In a room air conditioner, the air filter is typically located inside the air duct. This filter traps all contaminants in the air, including pet dander, dust, and mold spores. They should be changed every 30 to 60 days.

  • Heat pump: In a heat pump, the air filter is located inside the outdoor unit. This filter traps all contaminants in the air, including pet dander, dust, and mold spores. They should be changed every 30 to 60 days.
