OK, it looks like you bought a 092. That's the correct filter, and it will work fine with all of the current IR films.
Filters cut off at a point, and let in light beyond that.
Films are sensitive up to a point.
So a film is sensitive up to 820nm. A filter at 900nm would be too much (80nm over), but a filter at 720nm would be fine, since it would let in light at 720nm and above.
The B+W 092 is what I use with Konica, Ilford, Efke, and Rollei.
The B+W 091 is what I used with Kodak, since I could still see through a SLR lens.
