Product Details

  • Brand: Filter King

  • Model: FK24x45.5x1A-M8-4

  • Nominal Size: 24″ × 45.5″ × 1″ (standard frame size)

  • Actual Size: 24″ × 45.5″ × ~0.75″ (true filter thickness) 

  • MERV Rating: MERV 8 — captures common airborne particles like household dust, pollen, pet dander, and lint while allowing good airflow. 

  • Pack Quantity: 4 filters (the “-4” suffix indicates a 4-pack)

  • Material: Pleated synthetic filter media in a paperboard frame.

  • MERV 8 filters provide basic to moderate filtration suitable for most homes and light commercial spaces. They trap larger particles (≈3–10 µm) and improve indoor air quality without overly restricting airflow — good for everyday HVAC protection. 

🛠️ Typical Use

  • Install in return air grills or inside air handler/furnace filter slots sized for 24×45.5×1 filters.

  • Replace every 1–3 months depending on usage, environment (pets, dust, etc.), and season. Regular changes help maintain system efficiency and air quality.
