Aprilaire 1213 Filter Conversion Kit
Upgrade kit for Aprilaire and Space-Gard 2120 and 2200. Converts these models to take the Aprilaire 213 filter instead of the Aprilaire 201 filter. The newer 213 filter is more efficient (MERV 13 instead of MERV 10) and easier to install (slides into cabinet on tracks). Conversion kit includes conversion frame and one 213 filter. No tools required to assemble conversion frame.
This filter kit is also sold under OEM part number S1-FRKIT1213 for units made by Coleman, Luxaire, Source1 and York.
