Why MERV 13?

MERV 13 catches more fine particles (smoke, some bacteria, fine dust) than MERV 8 or 11, per the EPA MERV table. A 2-inch filter has more pleat area than a 1-inch panel, so MERV 13 usually adds less airflow resistance than it does in a thin slot. If your system is older or the filter clogs fast, check it monthly and change it when it looks gray.

FAQ

Is 20x20x2 the same as 20x20x1? No. A 20x20x2 is about 1.75 inches deep and a 20x20x1 is about 0.75 inches deep. Buy the depth printed on your current filter.

Which pack is cheapest per filter? On 25 Oct, the Filterbuy 20x20x2 MERV 13 12-pack ($11.41 per filter).

Why is the real size smaller than 20x20x2? Filter sizes are rounded “nominal” sizes. The actual frame is about half an inch smaller so it slides into a 20×20 slot.
