There are two problems here, and the one you mention is the least important of the two.
#1 Any kind of smoke will leave a greasy film on membranes found in electrostatics and ribbons. In my opinion, this is VERY likely to render the panels worthless in terms of performing to specification.
#2 The smell _may_ be eliminated by having the grille cloths replaced, as another poster mentioned.
I'd ask the seller to reverse the deal and eat shipping costs, due to nondisclosure.
