    "cleanest" air intake duct?
    I'm looking for the "cleanest" possible material for 8' of fresh air intake duct (no PVC, VOCs or other toxic materials). How does flexible aluminum duct (3" diameter, class 0) rate in terms of air quality?

    What about the new HDPE stuff?

    Any other suggestions?

    Thanks!
