You're best bet would be to PP it to Black and white rather than use filters.
For 35mm cameras the Red, Orange and yellow filters were the best. Red being the strongest (more contrast)
The other option would be an IR (infrared) filter. Shooting with the intention of turning your photos in B+W infrared, can produce some interesting results. For example, anything with foliage turns white, and blue skies turn black!
I hope this helps
