Allocated filter altitudes

This page lists filter altitude allocations by load order group. It is updated 1-2 times per year, so might not include any recently assigned allocations (see date on this page for last update).

Note

If you already have a Microsoft-assigned "integer" altitude, you can use it to create your own altitude to place a new filter in the same load order group. If you don't have a Microsoft-assigned altitude in the appropriate load order group, you'll need submit an altitude request.

To learn more about load order groups and altitudes, including how you can place filters at fractional altitudes based on your Microsoft-issued integer altitude, see "Load order groups and altitudes for minifilter drivers".

To see how a driver uses its altitude number in its INF file, see Creating an INF file for a filter driver.
