24x48x1 Aerostar Air Filter

About this product

The 24x48x1 Aerostar fits one of the longer rectangular returns in residential HVAC, measuring 24" x 48" x 1" actual. Returns in this size show up on larger homes and some light commercial applications where the system designer specified a single oversized return rather than multiple smaller grilles. Three MERV grades cover the typical filtration range. MERV 8 for baseline dust, lint, and pollen. MERV 11 for pet households or homes with mild allergy concerns. MERV 13 for fine particulate capture including bacteria, virus-carrying droplets, and wildfire smoke. Pleated synthetic media with an electrostatic charge built into the fibers handles the filtration. The pleats provide substantially more surface area than a flat fiberglass filter would at the same nominal size, which is what gets you the 60-to-90-day service interval under typical residential conditions. The electrostatic charge catches sub-micron particles where the physical weave alone reaches its filtration limits. Manufactured in the USA by Con-Air Industries at the Orlando, Florida facility. Cardboard frame, reinforced to hold shape under blower suction - critical at this length because longer filters experience proportionally more bending stress across the long axis, and a flexed frame allows air bypass at the edges where the seal matters most.
