Measuring for HVAC Filter Replacements
To understand the importance of a properly fitted furnace filter, think of your vacuum. When the bag is full, your vacuum no longer provides the right suction and cannot pick up dust and dirt. A dirty air filter for your HVAC system does not allow proper airflow to reduce contaminants.
In addition, an air filter that does not fit properly will have gaps in the sides. This allows for dust, allergens, and dirt to enter the HVAC system and potentially cause mechanical problems.
Width and Length
Look at your current air filter to see if there are any gaps on the sides. If not, you can take the measurements from the filter’s frame and shop for filter replacements. If you notice gaps, remove the old filter and measure with a tape measure for a snug fit.
Furnace filter replacements come in various thicknesses. The most common is 1″ thick. However, some specialty filters can be as high as 5″ thick. When measuring, also measure the depth of the frame where the air filter will be placed.
