Air filters fulfill a vital role in protecting your HVAC system from contaminants such as dust and debris, so homeowners need to make sure they are changed often. Learn more about what could happen if you fail to change your filter regularly, as well as how they help keep your HVAC system functioning and efficient.
How Do Air Filters Work?
Air filters are made from either spun fiberglass, pleated paper, or cloth and then embedded in a cardboard frame. They clean air that circulates through your HVAC system by trapping many types of particles that could affect your health and comfort. Significant functions of air filters include:
- Protecting the general health of occupants from lung-related infections
- Protecting children, the elderly, and those allergic to animal dander, mold spores, and pollen
- Reducing fire hazards by preventing lint and fibers from accumulating in ductworks
- Protecting household items from airborne dust
- Extending the shelf-life of perishable products by removing airborne mold
MERV Ratings and Filter Efficiency
Both air filter efficiency and performance are represented by the filter’s Minimum Efficiency Reporting Value, otherwise known as its MERV, ranging from 1 to 16. Lower MERV ratings imply that the filter is a standard model with basic to good filtration, usually at a lower cost and intended for residential buildings. A higher MERV indicates a higher-quality filter made to capture very small particles up to 0.3 microns. However, filters with higher MERV ratings tend to be thicker, so they can sometimes reduce heating or
cooling effectiveness and possibly damage the HVAC system.
How Do I Maintain My Filter
Regular maintenance such as checking and changing air filters ensures cleaner air and reduces energy costs in your home. You should change air filters at least once a month, especially in larger homes or homes with pets. Enlisting a professional is an easy way to ensure that your system is maintained accurately.
