Are all UV filters created equal?

Nope. what you need to look at is the bandwidth of the filter. basically the word UV describes the Ultra Violet end of the spectrum, biut this is split up into UVA, B, and C

Depending upon the application, and the film used, some will or will not be suitable. some of the lens elements in your camera in your camera may also filter out UV light

FWIW, UV light has not affected film for at least 20 years. Digital cameras have a UV filter on the sensor. UV filters are used for "protection" only these days. But that is another discussion!
