If you have a water filter with a charcoal cylinder, you could use a 1.0 micron element instead and filter the IPA. Chill it as much as you can (without freezing) and then filter. I first purchased a filter to clear up hop particles in Stiffy (a bastard born of a Wee Heavy & a Left-coast IPA).
Remember one unassailable statistic, as explained by the late, great George Carlin: "Just think of how stupid the average person is, and then realize half of them are even stupider!"
