filtered tap water

[Rusty]

Should I use a Pur water filter when i'm rinsing film? Will it make any difference?

Thanks,
Rusty

I'm just talking from 35mm B&W film but:
Ideally, you should used distilled water for the final rinse, but I best that if your filter is good, you won't have to worry about that too much. In addition, I do one rinse with photoflo, which helps prevent water spots.

I've always used tap water. Using filtered water will help ensure that no residue is left....but I just use tap water with photoflo or something similar...you can get chemicals under various brand names which help water flow off the film when it's dried.

Clean drinking water ("tap water") is fine, but should not have a high mineral content ("hard water"), which can cause water spotting. Photo-Flo or another rinse agent will help prevent water spotting.
