Typically, visual filters are not IR blocking (a requirement for CCD imaging due to the chip's sensitivity across a broad spectral band). As Paul indicates, you can use them, but you'll struggle to get the right colour balance due to IR leaks poisoning the signal. You can play around and perform G2V star tests to get close, but for what its worth I personally wouldn't bother. If you've got a good RGB set with a high transmission rating - stick with those.
