BYEWIRE Magnetic Vent Extender for Under Furniture - 10-12in Wide, Adjustable 17-33in

Bring precision airflow to rooms where air distribution often feels uneven. The BYEWIRE Magnetic Vent Extender is designed to vanish the gaps between your floor vent and the living area above. When placed under sofas, beds, desks, or near window sills, it gently redirects warm or cool air to where you notice the difference—creating a balanced feel without altering your room's decor. The result is a more even temperature with fewer drafts near seating areas, and the setup remains easy to reposition as your space evolves.

How it works

The extender uses a trapezoidal profile that directs air toward living spaces while minimizing visible gaps. It attaches securely to metal registers with strong neodymium magnets and a durable 1.5 mm thick material that holds its shape, even with temperature shifts. The design prioritizes steady airflow without bending or sagging over time.
