20x24x4 Commercial & Residential Aerostar Air Filter

About this product

The 20x24x4 Aerostar fits commercial and residential systems with a 4-inch filter slot, measuring 19 3/8" x 23 3/8" x 3 3/4" actual. The 4-inch depth is where pleated filtration earns its cost: substantially more media than a 1-inch can hold, much lower pressure drop across the filter face, and a service life measured in months rather than weeks. MERV 8 covers baseline residential and light commercial filtration. MERV 11 handles pet households and most allergen concerns. MERV 13 captures fine particulates including smoke, bacteria, and virus-sized droplets - the recommended grade for healthcare, food service, or any indoor environment where air quality matters more than minimal cost. The cardboard frame is reinforced for the higher airflow rates commercial blowers generate, which can collapse weaker filter frames. Pleated synthetic media with an electrostatic charge handles the work, manufactured by Con-Air Industries in Orlando, Florida. Service life is 6 to 12 months in residential use, 3 to 6 months in light commercial applications. Pressure drop is the actual change indicator - if your system's static pressure gauge climbs significantly above clean-filter baseline, that's the signal to swap, regardless of how long the filter has been in service.

• Pleated synthetic media with electrostatic charge: Captures fine particulates, bacteria, and virus-sized droplets for superior filtration
• Reinforced cardboard frame: Maintains structural integrity at higher airflow rates, preventing collapse in commercial blowers
• Multiple MERV ratings: Supports MERV 8, 11, and 13 for tailored filtration from baseline to advanced air quality
• Long service life: Lasts 6 to 12 months in residential use and 3 to 6 months in light commercial applications, reducing maintenance frequency
• Low pressure drop design: Minimizes system load and energy consumption while maintaining effective filtration
