High performance fan works by introducing replacement air at a reduced rate to maintain a slight negative pressure in the room being ventilated, to ensure fresh air is brought in from the rest of the house and preventing humid air from migrating. Also uses a thermal accumulator to extract warmth from outgoing air to temper incoming air, helping to avoid feeling cold drafts and recover heat that would be lost to the outside.
