About 20x21 5/8x1 Aerostar Air Filter

Actual Size: 20"x21 5/8"x1" Product: P80S.012021K-6 8 Fights: Dust & Pollen

A 20 x 21 5/8 x 1 nominal return is one of those odd specs that comes from a custom or semi-custom HVAC installation. This Aerostar measures 20" x 21 5/8" x 1" actual, built to the exact spec without adjustment. MERV 8 covers standard residential filtration: dust, lint, pollen. MERV 11 handles pet households and mild allergy concerns. MERV 13 captures fine particulates including smoke, bacteria, and virus carriers - the recommended grade for households with asthma or chronic respiratory health issues. Pleated synthetic media with an electrostatic charge built into the fibers handles the filtration work. The pleats provide several times the surface area of a flat fiberglass filter at the same nominal size, which extends the service life to a 60-to-90-day window under typical residential conditions. The electrostatic charge catches sub-micron particles where mechanical filtration alone reaches its physical limits. Manufactured in the USA by Con-Air Industries at the Orlando, Florida facility. Cardboard frame, reinforced to maintain shape under blower suction. Custom-spec filters benefit most from dimensional precision because an off-spec filter leaves a gap where unfiltered air bypasses the media, which defeats the purpose of running any MERV grade above the baseline.

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: 4.5 / 5 from 2 reviews.
