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”

The 12x24x2 Aerostar measures 11 3/8" x 23 3/8" x 1 3/4" - the 2-inch nominal depth means a longer service life than a standard 1-inch and noticeably lower static pressure across the filter, which is easier on your blower motor. Two-inch filters were standard in older residential systems and remain common in light commercial applications. The deeper pleats hold roughly twice the debris of a 1-inch equivalent before reaching the same pressure drop. MERV 8, 11, and 13 options cover the same residential and small-commercial filtration range. MERV 8 is your baseline for standard dust and pollen. MERV 11 covers pet households and most allergy concerns. MERV 13 handles fine particulates including smoke, bacteria, and virus carriers - run this grade if anyone in the home has asthma or if wildfire smoke is a recurring problem. The pleated electrostatic media is manufactured by Con-Air Industries in Orlando, Florida. Expect a service life of 4 to 6 months on MERV 8 and 11 in normal residential use, dropping to 2 to 4 months for MERV 13 or in heavier-load environments like homes with multiple pets or active cooking schedules.

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.

The Aerostar brand is known for constantly innovating and improving their technology to help make filtration more efficient, effective and environmentally friendly every day.
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.
