About 19 3/4x21 1/2x1 Aerostar Air Filter

Actual Size: 19 3/4"x21 1/2"x1" Product: P80S.0119M21H-6 8 Fights: Dust & Pollen

The 19 3/4 x 21 1/2 x 1 Aerostar fits a return that nominally would be called a 20x22x1 but actually measures 19 3/4" x 21 1/2" x 1". Odd-sized returns like this appear in custom HVAC installations and certain regional construction markets where the original installer didn't size to a standard nominal opening. MERV 8 covers standard residential dust and pollen filtration. MERV 11 handles pet households and most common allergens. MERV 13 captures fine particulates including smoke, bacteria, and virus carriers - the grade for households with respiratory issues or in wildfire-affected regions. Pleated synthetic media with an electrostatic charge built into the fibers does the actual filtration work. The pleats give you substantially more surface area than a flat fiberglass filter at the same nominal size, extending the service life to a 60-to-90-day window in typical residential conditions. The electrostatic charge catches sub-micron particles where the physical weave alone reaches its limits. Manufactured in the USA by Con-Air Industries, Orlando, Florida. Cardboard frame, reinforced to maintain shape under blower suction. Odd-size filters benefit most from dimensional precision because an off-spec filter leaves gaps where unfiltered air bypasses the media entirely.

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 (Minimum Efficiency Reporting Value):

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.

Overall rating: 5.0 / 5 from 3 reviews.
