• Keep it simple. Plan for a minimum of bends and joints.
• Keep the length of outside insulated duct to a minimum (not for HEPA 1000).
• Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the
exhaust air from a dryer or a range hood. This would cause clogging of the
filters and recovery module (if applicable).
• If the house has two floors or more, be sure to plan for at least one exhaust
register on the highest lived-in level.
