The filters in Thomas Duplex Super Safelights will deteriorate with age and should be examined periodically to ensure that the light is still properly filtered. The manufacturer recommends replacing the filters every 5 or 6 years. If you require replacement filters for the model DUB safelight (for B&W papers and ortho materials), or model DUC (for color and B&W papers), this is the set of yellow edge filters that fit in the body of the safelight.
FOD ortho (red edge) and FCD color (black edge) filter sets are also available - please see the separate listings.
