*Percentages are the approximate free-airspace figures stated in the product copy, not CFM ratings or size-specific net free area. They do not establish how much airflow an installed door will deliver. Privacy levels are not quantified in the listings; only the quoted wide flat-slat privacy option is expressly described for privacy uses.
Mechanical-room and air-handler sizing: Do not select an insert for furnace, mechanical-room intake or an air-handler requirement from its style or percentage alone. Sizing must follow the equipment manufacturer's required net free area. Confirm the size-specific net free area and installation suitability with the equipment manufacturer or a qualified HVAC professional before ordering or cutting the door; these listings do not state CFM ratings or establish mechanical-room suitability.
Slat orientation and fit: The pad-with-molding listing states that its chevron slats slope down on both sides. Orientation is not specified in the other listings; confirm it before installation rather than assuming it from the style name. Measure actual door thickness, since nominal door sizes can vary, and follow the selected product's cutout instructions.
