Welcome. I hope you find this forum to be as informative and friendly as I have!
I would do a bleach dip on the filter parts. 20 parts water to 1 part bleach. Let it soak for 10 to 20 minutes, rinse really really well, and place them in a bucket of water with 3xs the dosage amount of DeChlor for a day or two. And then I usually rinse it again.
I don't know if others have bleached driftwood, but I would think it would be very difficult to remove soaked in bleach water. Spraying it really well with some Hydrogen Peroxide should do the trick or boil the heck out of it.
