Amazon Basics MERV 5 Furnace Air Filter — 20x20x1 Inches, 6-Pack (Actual 19.75x19.75x0.75)

Cleaner air, simple maintenance: Amazon Basics MERV 5 Furnace Air Filter

Designed for standard 20x20 filter slots, this Amazon Basics option arrives as a practical 6-pack, making it easy to keep multiple rooms or seasonal needs covered. The filtration media is designed to be electrostatically charged, pulling in particles as air passes through while the sturdy beverage board frame and wire mesh help keep the filter securely in place. This combination aims to balance filtration with airflow so your heating or cooling system can operate smoothly without frequent filter changes.

The MERV 5 rating indicates a middle-ground filtration level, suitable for everyday environments where a steady flow of air is important. The actual size is slightly smaller than a typical 20x20 opening, measuring 19.75" x 19.75" x 0.75". That precise sizing helps you verify compatibility with your unit before swapping in a new filter, reducing the chance of installation issues and ensuring a snug fit when you line up the edges with the frame.
