I gave up on finding a replacement and adapted the old filter so the iron can be used without the filter material inside it. Carefully remove the top to your last used filter (small flat blade screw driver inserted at the lift on the filter top, tap the driver til lid seperates.) Remove granules and sponge filters. Clean contact edges lightly with PVC cleaner and then apply PVC glue to contact edges. Press top on and hold for a minute, let cure, then return it to the tank. From then on use only distilled water. Run Iron with steam wide open to remove any and all discoloring spray and sludge from line....Good luck!
