You can build a positive pressure filtering cardboard box by using a muffin fan and a cat box activated carbon filter.
12 Volt muffin fan = $8.00
Activated carbon filter (cat box) = $1.50 each
Mount filter in side of box, place album, in box, mount fan on other side of box. Seal box well to prevent air flow from anywhere but the carbon filter. Use 12V power supply (any old 12V supply will work) or battery pack to power fan.
Takes about 48 hours to remove all smells.
