About

  • Whole-House Replacement: Accordion-style, expandable air filters for your furnace or air cleaner. A 4-inch media filter that drops into AprilAire whole-house housings and works with furnaces, air conditioners, heat pumps, and central HVAC systems. Available in eight sizes (see the size and compatibility list below).
  • Two Filtration Levels: Choose MERV 11 for everyday particle capture, or MERV 13 for the highest level of residential filtration. Pick the model that matches your system.
  • MERV 11 Performance: MERV 11 synthetic media (comparable with MPR 1200 & FPR 7) captures fine particles including pollen, mold, dander, smoke, smog, and lint without impacting air flow. Electrostatically charged design with 11 pleats per foot.
  • Made in the USA: Every component is manufactured in the United States with recyclable materials — built here, not imported and repackaged.
  • Advanced Electrostatic Media: Synthetic, electrostatically charged media works like a magnet, pulling in and holding fine particles that basic fiberglass filters let slip past. Deep 4-inch pleats add surface area to capture more without choking airflow.
  • Go ~6 Months Between Changes: High dust-holding capacity means one filter keeps working for up to 180 days — about 6 months, and up to 3x longer than fiberglass models. Fewer swaps, less hassle, less strain on your system.
  • Built to Hold Up: Sturdy, recyclable frames with dual wire backing keep their shape instead of warping or collapsing like cardboard, standing up to temperatures up to 200°F and exposure to moisture. Slide it in and it stays put.
  • Easy to Install: Printed airflow arrows show exactly which way the filter goes in. Pull the old one, slide the new one in, done.

Product Description

Keep your AprilAire air cleaner running its best with a Filterbuy 4-inch accordion-style, expandable replacement filter for your furnace or air cleaner. Designed for furnaces, air conditioners, heat pumps, and central HVAC systems, these filters circulate cleaner air through your home without making your equipment work harder.

Here's how they do it. An electrostatically charged, pleated synthetic media draws in airborne particles as air passes through. MERV 11 models capture pollen, mold, dander, smoke, smog, and lint while trapping 95% of dust particles without impacting air flow (comparable with MPR 1200 & FPR 7). MERV 13 models reach finer particles, including bacteria, while trapping 98% of dust particles (comparable with MPR 1900 & FPR 10) — the highest level of residential filtration.

High quality construction (made in the USA) features an electrostatically charged design that captures more harmful particles and lasts 3x longer than fiberglass models. Easy installation, recyclable frames with dual wire backings improve structural integrity and outperform standard cardboard designs by resisting extreme temperatures and moisture. Line up the printed airflow arrows, slide the filter into your housing, and you're set. Replace every 180 days for best performance, or sooner in homes with pets, heavy cooking, smoke, or ongoing renovation. Available in 1-, 2-, 3-, and 4-packs.
