What are the habitable zone parameters for the Epsilon Eridani star system?

I'm writing a novel about a habitable planet that's about the size between Earth and Mars, and I need to know what the distances are between the inner-most and outer-most edges of the HZ. But would this orbit intersect with the dust halo around the star, and, if so, would it be possible to have a habitable planet inside the dust halo?
