I have heard of people putting cheap vodkas through a carbon filter (like Brita) a few times to improve smoothness. I haven't tried it myself, but I am skeptical, because if the fix is that easy then it seems like the producer would have done it. MythBusters did a double-blind taste test[0] in which only the "vodka expert" was able to correctly rank the samples, and they found that the chemical composition of the cheap vodka was the same before and after filtering. Based on that, I would say the answer is most likely "no" and you should spend a few more bucks.
