- Fiberglass Filters: These are common and inexpensive, but offer lower efficiency.
- Electrostatic Filters: These filters use electrostatic charges to attract and trap airborne particles.
- HEPA Filters (High-Efficiency Particulate Air): These high-efficiency filters are designed to capture a greater percentage of airborne particles, including allergens and pollutants. Measuring these requires precision.
2. Locating the Air Filter
Your air filter’s location depends on your HVAC system’s design. Common locations include:
- Furnace/HVAC Unit: This is the most common location. The filter usually sits within a compartment accessible through a door or panel.
- Return Air Vent: In some systems, the filter is located within the return air vent, typically found on walls or ceilings.
3. The 5 Easy Steps to Air Filter Measurement
Accurate air filter measurement is crucial. Follow these five straightforward steps:
- Preparation: Turn off your HVAC system before you begin. This ensures your safety and prevents accidental damage.
- Remove the Old Filter: Carefully remove the old filter, paying close attention to its orientation and how it sits inside the housing unit.
- Measure the Dimensions: Use a ruler or measuring tape to measure the filter’s length, width, and depth. Record these dimensions accurately. It’s helpful to measure each dimension twice to check for consistency. Remember to measure the actual filter – not the frame.
- Note the Orientation: Take note of which side of the filter faces the airflow. This information is crucial for correct installation. Often the direction of airflow is indicated on the filter itself. The direction of airflow is vital and should always be checked before replacing the filter.
- Record Your Measurements: Write down the length, width, and depth of the filter, including the units (inches or centimeters).
4. Understanding Air Filter Sizing Conventions
Air filter sizes are often expressed in a specific format, such as “20x25x1”. This represents length x width x depth in inches. Sometimes, you will see slightly different representations, where the width may be listed first (25x20x1). This emphasizes the importance of always double-checking your measurements and comparing them carefully to the filter specifications. Always confirm the sizing convention before purchasing replacement filters.
5. Finding the Right Replacement Filter
Once you’ve accurately measured your air filter, you can easily find a suitable replacement. Online retailers and home improvement stores commonly use this method of sizing. However, remember that the manufacturers may slightly differ in their dimensions, offering filters that slightly increase or decrease filter size to fit more easily.
Choosing the Right Filter Efficiency
It’s not just size that matters; choosing the correct efficiency rating is also important. Consider the following:
- MERV Rating (Minimum Efficiency Reporting Value): This rating indicates the filter’s ability to remove particles from the air. A higher MERV rating means better filtration, but it might also restrict airflow.

- Your Specific Needs: If you have allergies or asthma, a higher MERV rating filter might be beneficial. However, a filter that is too efficient may restrict airflow, impacting the efficiency of your HVAC system.
6. Common Air Filter Measurement Mistakes to Avoid
Several common mistakes can lead to incorrect measurements and improper filter selection.
- Measuring the Frame: Only measure the filter media itself, not the frame.
- Inconsistent Measurements: Always double-check your measurements to ensure accuracy.
- Ignoring Filter Orientation: Make sure to note the direction of airflow to ensure proper installation.
7. Air Filter Maintenance and Replacement
Even with the correct sized filter, regular maintenance is essential.
Frequency of Replacement
The frequency of air filter replacement depends on several factors, including the type of filter, the amount of dust in your home, and the number of people living in your house. Consult your HVAC system’s manual for guidance, but generally, most filters should be inspected and replaced at least every 3 months. Check the filter frequently, and replace it when visibly dirty.
