There’s no questioning the ubiquity of pleated air filters. As one of the most commonly found filters found in the heating and cooling systems of residential homes, pleated filters offer a myriad of advantages over other filter alternatives.

What is a pleated filter’s primary purpose?

 

Pleated filters are typically manufactured from polyester, paper, or cotton material folded down into pleats. The pleats increase the surface area of the filter product, and this enables the filter to trap more airborne particles that can accumulate and negatively impact your HVAC system’s blowers fans and AC coils. 

 

Why are pleated filters so popular?

 

Pleated filters are more durable, cost-effective, and efficient than fiberglass filter alternatives. They also typically come in a wide range of sizes, and are flexible enough to accommodate most air handling systems.

- The filter is grey and you can see visible dirt and dust build-up on the filter surface

- You notice more dust than usual inside your home

- Your HVAC system is not as efficient as it could be - heating and cooling cycling takes more time than before

- The filter has been installed for longer than the manufacturer’s recommended use 

 

If you notice any of the above, it might suggest that it’s time to opt for pleated filter replacement. 

 

What are some other considerations I should factor into deciding when to change my pleated filter?

Other considerations include MERV ratings - filters with lower ratings require more frequent replacement. If you are using pleated filters for your furnace system, it will also likely require more frequent replacement depending on how often you put your HVAC system to use.
