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”
View Detailed InstructionsAbout 25x30x1 Aerostar Air Filter
The 25x30x1 Aerostar measures 25" x 30" x 1" actual, sized for a nominal 25x30x1 return on larger residential systems. Returns in this size appear on furnaces serving 3,000-plus square foot homes and on some compact light commercial units. MERV 8 covers baseline residential filtration. MERV 11 handles pet households and most common allergens. MERV 13 captures fine particulates including bacteria, virus carriers, and wildfire smoke - the grade for households with respiratory health issues. Pleated synthetic media with an electrostatic charge built into the fibers handles the actual filtration. The pleats give you substantially more surface area than a flat fiberglass filter would offer at the same nominal size, which extends the service life to 60 to 90 days under typical residential conditions. The electrostatic charge catches sub-micron particles where mechanical filtration alone reaches its physical limits. Manufactured by Con-Air Industries in Orlando, Florida. Cardboard frame, reinforced to maintain shape under blower suction. Larger residential systems run their blowers longer than smaller systems on a per-day basis, which means the filter loads up faster on a calendar basis - plan on the shorter end of the 60-to-90-day range for MERV 8 and 11, and closer to 30 days for MERV 13.

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.
About MERV, MPR and FPR Rating
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 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 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.
