IR Filter with WebCam

I have a webcam and adapter on order, and have been reading about IR filters. Several sources indicate they are only needed with refractor type telescopes. I'm not sure that is accurate. I will be be using reflectors, and would appreciate brand names of IR filter if needed.

Thanks,

Brad

The IR cut filter is useful if you plan to image mars, even if you are using reflector scopes. Some webcams are more sensitive to infrared than others, so the effect varies. I'm using the Baader UV-IR cut filter with a ToUcam Pro on a 10" newtonian. Here's an image I processed from frames taken on the morning of the 28th:
