Hi,
I don't have a filter for sale, but I do have an Ilford SL1 for sale if you might be interested in that? It's one of the better safelights around.
The specs can be found here. It also lists what kind of paper these are safe for:

I could sell it to your for 25. Shipping will be 9 without tracking, 13 with tracking and in the unlikely event the package will be more than 2kg it would be 19.
Let me know what you think.
