To get the most out of their air conditioner, most homeowners are aware that they need to change the filters regularly. However, most people remain completely in the dark as to how often their AC unit needs servicing. This keeps the filters clean, and it’s how their HVAC system relies on clean filters to provide high-quality air throughout their home. Buying the right filters for your air conditioner means knowing which size you need, how often to change them, and which type will be the most efficient for their unit. 

Below are three things all homeowners should know about replacing the filters for their air conditioner:

• Select a Size: The first step for choosing a new air conditioner filter is determining which size you need. HVAC filters come in a variety of sizes, varying in both surface area and thickness. As a general rule, homeowners should know that a tight-fitting filter works best, so it’s important to measure the filter’s frame before shopping around. Look for a filter that won’t leave any gaps around the perimeter when it’s installed. The thickness of a filter will range between one and four inches, but it’s important to check your system’s requirements before choosing the thickest filter, as it may not fit at all. 
• Find Your Type: There are many different air conditioner filters, each of which provides a unique performance level and requires a different form of maintenance and upkeep. Disposable fiberglass filters are cheap, but they only catch larger particles. Disposable pleated filters pick up both small and large particles and usually have to be changed more often than other types. Disposable electrostatic filter options have electrically charged fibers, which help catch tiny particles but can be a bit more on the expensive side for the average homeowner. Lastly, a permanent electrostatic filter has charged fibers, like its disposable counterpart, but don’t collect as many particles. The draw is that they can be machine washed, making them very economical. 
• Consider Efficiency: The Environmental Protection Agency rates each air conditioner filter according to how well it catches particles. The number (between one and 13) indicates how effective the filter is. The higher the rating is, the more particles the filter can catch. Unfortunately, the greater the efficiency rating, the lower the airflow, which can lead to the need for more excessive use and higher monthly utility bills. If you’re unsure of which filter is right for your family’s needs, ask an HVAC professional for their opinion.
