Last year I posted a similar query, albeit using my Saunders LPL 4550 XLG (which, as far as I can tell from the manual, does not have replaceable filters like the Durst).I am glad to see this topic revisited, the answers are helpful and give me several avenues of exploration since I have been wrestling w/the same issue.I recently came across this online article about safelights on Paul Butzi's website:http://www.butzi.net/reviews/darkroom.htm#Safelights%20(Thomas%20Duplex,%20Patterson)---------jump down to safelight section by clicking link on the left-hand list
Both Kodak and Ilford have procedures for testing safelights. Kodak's is called K-4. I can send it to you if you can't find it on their web site. The procedures are not identical but both test for the sensitization effect of the safelight on the paper. This can result in fogging even when a simple exposure to the safelight without also being exposed to the enlarger image can cause fogging.
