24x24x1 (Actual size 23.5x23.5x0.75) Inches Air Filter MERV 8, AC Furnace

The Fit: While the frame says 24x24x1 (the rounded nominal size), its true physical measurement is 23.5 x 23.5 x 0.75 inches. Always check your existing filter or slot to ensure this exact actual size fits snugly without bending.

The Filtration (MERV 8): This is the "sweet spot" for standard homes. It captures up to 90% of common airborne particles like dust, lint, pollen, mold spores, and pet dander.

Airflow Efficiency: Because it is a MERV 8, it traps debris effectively without restricting your furnace or AC airflow, helping to prevent system strain and keep your energy bills lower than higher-rated filters might.

Lifespan: It needs to be replaced every 60 to 90 days. If you have pets or allergies, you should check it closer to the 60-day mark.
