What jumertens said.
I try my best to filter as much hops out when I transfer the wort to my fermenter, I have a stainless steel, mesh thingy that does a pretty good job but, yeah, little bits can still get through. Especially if I use pellet hops.
When I make IPA's, I typically end up having some hoppy sediment at the bottom of my bottles. I can reduce it by carefully racking from my primary fermenter to a secondary (which I don't always like to do) and also by conditioning the beer for a longer time before bottling so that the hops pack down with any yeast trub.
But, the reality is that I don't worry too much if there's a little hop dust in my brews.
