About 20x21 1/2x1 Aerostar Air Filter

Actual Size: 19 7/8"x21 1/2"x3/4" Product: P80S.012021H-6 8 Fights: Dust & Pollen

At an actual 19 7/8" x 21 1/2" x 3/4", the 20 x 21 1/2 x 1 Aerostar fits a return that doesn't conform to a standard nominal size - common in custom builds and certain regional HVAC markets where the installer specified a non-standard grille opening. MERV 8 handles baseline residential filtration. MERV 11 covers pet households and mild allergy concerns. MERV 13 captures fine particulates including bacteria, virus-carrying droplets, and wildfire smoke - the grade for households with respiratory health issues. Pleated synthetic media with an electrostatic charge built into the fibers handles the filtration. The pleats give you substantially more surface area than a flat fiberglass filter at the same nominal size, which extends the service life to 60 to 90 days under typical residential conditions. The electrostatic charge improves capture of sub-micron particles where the physical weave alone reaches its filtration limits. Manufactured by Con-Air Industries in Orlando, Florida. Cardboard frame, reinforced to hold shape under blower suction. Odd-size returns benefit from precise dimensional matching because a filter that's even slightly off-spec leaves a gap where unfiltered air can bypass the media entirely - the worst outcome if you're running a higher MERV grade to filter for health reasons.

Designed for Superior Filtration Efficiency

Made with electrostatically charged synthetic material that draws and captures allergens between 3 - 10 microns, including lint, dust mites, mold spores, pollen, pet dander, and dust.

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.
