What Pete said only more so.
There are a couple of ways that you could have a haze. If we know how your mead got to the point it is, we can help you with where it is now. The more we know about the temperatures involved, the ingredients, the yeast strain, the timings, the gravities when it started and where it is now, the pH, etc. the better we can help you.
There are a lot ways to make mead, some work better than others. Without knowing how you made this one, we really can't point you to a definitive answer.
And don't worry so much about the chemicals. Many full grape wines have higher concentrations of sulfites than any you might add to any mead. Any other "chemicals" you might add (nutrients, re-hydration enhancers, stabilzers, etc.) are usually a result of a natural process. It's really not a concern if you've looked at any of them for a while.
Oh, and Welcome To GotMead?! meadmonkey!
