Transits are great
the thing about Jupiter is that there's always something going on...it'd never static, with all the surface features and moons catapulting around.
I don't use a filter, I just let my eyes adjust. If you find it too bright, increase the magnification a bit as the object will dim slightly with increasing magnification. The seeing will determine how high you can go and keep the image looking crisp, and it can be fun trying too. Personally, I prefer to have a crisper image than a larger one, but sometimes you can have your cake and eat it
