Twelve 10x18x1 MERV 11 pleated furnace filters. Actual size is slightly under the nominal 10x18x1 — measure the old frame before you order. Traps household dust, pollen, and pet dander in that airstream. Swap about every 90 days. This is a furnace filter, not a HEPA room purifier and not a medical device. Write the size on the slot so the next pack is one click.
