Frequently Asked Question

Figuring out the size of air filter you need is crucial to ensure the HVAC system runs properly. An undersized filter will clog quickly, decrease air flow and let dirt particles slip through. This can cause the filter and grill to vibrate and whistle, which is not only annoying but can indicate that air is being drawn in from tiny cracks.


To combat this, the recommended minimum filter surface area is 2.50 cubic feet per minute (cfm) per square inch of filter area. For example, with a 2000 cfm system, you would need a filter of 800 square inches, or a 20' X 40' filter grill.


For best results, use 2.00 cubic feet per minute per square inch of filter area. With a 2000 cfm system, you would need a filter of 1000 square inches, or two grills of 20' X 25' each. This formula works in all residential applications, and using 2.00 cfm per square inch of filter area will ensure an air velocity of 300 feet per minute or less in 1 through 5 ton units.


In situations where space is limited, a disposable filter may be placed in the return duct. When doing so, be sure to consult the manufacturer's literature on the return grill size as to avoid noise and decrease restrictions.

Do you need an exact size air filter? The answer is yes! Without the right size filter, your HVAC unit won't be able to function properly and you won't get the full benefits of an air filter.

The actual size is found on the filter frame, and it can vary by brand. Some less common sizes come true to size, which means the nominal size and the actual size are the same.


If you have to bend, force, or jam your air filter into place, it's too big. On the other hand, if it doesn't come within 1-2 fingers' width of all four corners of your air system handler's slot or frame, it's too small. The best-fit filter should fit into the slot or frame easily, without needing to be bent or smashed.


In summary, make sure to pick the right size air filter for your HVAC unit. It should fit into the slot or frame without needing to be forced or bent. This way, you'll get all the benefits of an air filter and your unit will run smoothly.

It is important to buy the right size HVAC air filter. Using the wrong one can cause your heating and cooling system to become inefficient and reduce the quality of your indoor air.


Using the wrong size filter or installing it incorrectly can lead to dust accumulating on the system's motors and blowers, which will reduce the system's performance. The type of filter you should use depends on your system and your needs, but could range from spun fiberglass, pleated paper or polyester fibers, and electrostatic pleats. You can also choose from washable or disposable filters.


No matter which type of filter is best for you, make sure to change or clean it regularly to maintain healthy air quality. Each filter also has a Minimum Efficiency Reporting Value, or MERV rating, which tells you what size particles it can trap. If you want to use a high-efficiency HEPA filter with a rating above 13, make sure your system is designed to work with them. Otherwise, the filter can block airflow and cause more harm than good.

When looking for an air filter size, understanding the standard stock size is key. This means that the HVAC unit's filter is a widely-available size that is easy to purchase. Popular examples include 16x20x1, 20x20x1, 16x25x1, and 20x25x1. It's important to make sure the right size filter is installed, as the wrong size can lead to air seepage and create added stress on the HVAC system, potentially damaging it and increasing energy bills.
