How to Measure Your Filter
Steps 1 & 2
Measuring Length and Width (L x W). (If your filter is not a square, the smallest measurement goes first).
Step 3
Measure the thickness (Depth) of your filter from front to back.
Step 4
Put Your measurements together (L x W x D).
Actual Size
A filter’s true dimensions.
Example: 19.75” x 19.75” x 1”
Nominal Size
Rounded numbers used by manufacturers.
Example 20” x 20” x 1”

Improve Indoor Air Quality
Protect your family and loved ones with clean indoor air quality at home. Aerostar filters are a simple and cost effective step towards a healthier home environment, free of airborne allergens and particles that can trigger various allergy and asthma symptoms.
Improve Efficiency and Reduce Cost
An Aerostar furnace air filter helps keep your HVAC unit working efficiently by removing dirt and reducing strain on the motor. When your unit runs properly, it consumes less energy, requires less maintenance and will have a longer life. These factors will have an impact on your utility bill and maintenance costs. It is recommended that you change the filter every 60 to 90 days during normal times of year but increase frequency to 30 days during peak summer and winter months when your unit is working the hardest.

About MERV, MPR and FPR Rating
The three rating systems were created by different organizations. MERV is the domestic and international Industry Standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. The other two rating systems were created by 3M and The Home Depot, but all are rating the same filter.
MERV Rating (Minimum Efficiency Reporting Value): As you have already learned, the MERV Rating is the primary rating system used in the industry, both domestically and internationally. Established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, MERV rates a filter’s ability to capture and hold particles and pollutants.
MPR (Micro-Particle Performance Rating): MPR Rating is a rating system developed by 3M. It rates the manufacturer’s Filtrete product line and their ability to capture airborne particles smaller than 1 micron.
FPR (Filter Performance Rating): FPR Rating is a rating system developed by The Home Depot for brands sold through their stores, including Honeywell. It utilizes a color code and number scale (4 to 10) that closely resembles the MERV rating.
What is a MERV Rating?
MERV ratings let you know the efficiency and level of filtration that an air filter can handle under normal circumstances. The higher the MERV rating, the finer the particles are that are filtered our of the air in your home. Many air filter retailers use MERV or a similar rating to rate their air filters.

FAQs
Replace your 16x25x1 furnace filter every 60 to 90 days to achieve more breathable indoor air. If your home runs the HVAC system more during summer and winter months, change it every 30 to 60 days to prevent the HVAC system from straining. If it gets clogged or looks dirty, switch it out sooner to ensure your system runs smoothly and to improve air circulation.
Homeowners prefer using 16x25x1 air filters with a MERV 11 rating because they efficiently trap a wider range of fine airborne particles and make the air more breathable in their home. If your HVAC system isn’t capable of higher filtration, then increased resistance could affect airflow. Read your HVAC manual for the specifications about your unit to ensure it can use a MERV 11 filter, or request help from an HVAC technician.
Width is the main difference between a 16x20x1 and a 16x25x1 air filter. Because of its larger surface area, the wider 16x25x1 filter captures more dust, pollen, and debris to achieve better filtration and indoor air quality. The filter slot size in your HVAC system will determine which type you can use. While 16x20x1 filters fit into smaller units, they may need to be changed more frequently.
Thicker air filters may restrict airflow more than a 1 inch filter, like the 16x25x1 type. If your HVAC system isn’t compatible with thicker filters, don’t use them because they might create more resistance. You can check the specifications in your HVAC manual to see which types of filters and MERV ratings work best in your unit.
If you use an air filter that isn’t the right size, it can affect filtration, and your HVAC system will be less effective. Gaps might cause unfiltered air to circulate if the filter doesn’t fit properly or is too big. Harmful particles could bypass the filter if it's too small. Using the proper size filter supports proper airflow and extends the life of your HVAC unit.
The exact size of an air filter is important if you want to make sure your HVAC system operates properly. If it doesn’t fit correctly, less filtration will occur, and unfiltered air could circulate in your living space. Air filters are designed to fit snugly in their slot and prevent unfiltered air from flowing through your home. If a filter is too big, it may restrict airflow, and if it's too small, particles might bypass it. Use the correct size air filter to maintain optimum airflow and protect your HVAC system from unnecessary wear.
