How to Measure HVAC Filters

To find the correct replacement, measure the length, width, and depth of your existing filter. Most filters are labeled with a nominal size (like 16x24x1), which is a rounded number—actual measurements are often slightly smaller. Accurate sizing ensures a proper fit and helps maintain airflow efficiency.

How to Measure HVAC Filter

Step 1: Remove Old Filter

Turn off your system and remove the existing filter. Look for printed dimensions on the frame—this is usually the nominal size.

Step 2: Measure Actual Size

Use a tape measure to get exact dimensions (length × width × depth). Round down to the nearest 1/8" if needed—example: 15-5/8" × 23-5/8" × 3/4".

Step 3: Match or Order Custom

If your measurements don’t match a standard size, we offer custom filters made to your exact dimensions.
