Upgrade your indoor air quality with Aerostar 16x25x4 MERV 8 filters

Meet the Aerostar 16x25x4 MERV 8 pleated air filters, sold as a convenient 6-pack. With an exact size of 15.50 x 24.50 x 3.75 inches, these filters are designed to fit most standard 4-inch filter slots, making a straightforward upgrade for many homes or small offices. The simple, cost-effective design aims to help you maintain a comfortable living space while keeping your HVAC routine simple.

How the filtration works

The filter uses a premium electrostatically charged synthetic media. As air passes through, particles in the 0.3 to 1.0 micron range—such as dust, pollen, lint, and pet dander—are drawn toward and captured by the pleated surface. This helps reduce visible dust and may contribute to a fresher indoor atmosphere between swaps.

• UNIVERSAL COMPATIBILITY: Fits most standard residential and commercial HVAC systems with a 4-inch slot, including Lennox, Carrier, Bryant, Payne & Honeywell. Actual size 15.50 x 24.50 x 3.75 inches; comparable to Filtrete MPR 600 and Honeywell FPR 5.
• EFFICIENCY AT A GLANCE: MERV 8 filtration captures up to 90% of common airborne particles like dust, pollen, pet hair, and mold spores.

Performance and reliability

The design emphasizes enhanced airflow through electrostatically charged media, helping to maintain steady air movement while filtering a broad range of particulates. The long-lasting construction features a heavy-duty beverage board frame, moisture-resistant backing, and reinforced pleats, supporting reliable filtration over several months in typical environments.

• LONG-LASTING CONSTRUCTION: Durable frame with moisture resistance supports multi-month filtration in many settings.
• ENERGY- AND MAINTENANCE FRIENDLY: Cleaner air and reduced dust buildup may contribute to easier HVAC upkeep.
