BESWEL Air Vent Extender for Under Furniture – Magnetic Floor Vent Deflector (17–48 in, 12 in Wide, 1.5 mm Thick)

Rethink airflow under furniture with BESWEL

The BESWEL Air Vent Extender helps you manage the flow of conditioned air from vents that sit beneath sofas, beds, or cabinets. Rather than letting drafts escape or air pool in one corner, you can guide a balanced stream along the floor where it matters most. The result is a more even room feel and a cleaner aesthetic that blends with your decor, without requiring dramatic changes to your HVAC setup.

Designed to adapt to real rooms, the extender stretches from 17 to 48 inches in length and works with vents up to 12 inches wide. Its slim 12-inch width keeps a low profile while still providing meaningful coverage to influence airflow direction. The 1.5 mm thick PET plastic offers both clarity and stiffness, helping maintain shape after repositioning and seasonal layout changes.

Key benefits

• Effortlessly reroute airflow from vents tucked under furniture for more even heating or cooling.
• Adjustable length from 17 to 48 inches and up to 12 inches wide fit many spaces and layouts.
• Clear, durable PET plastic blends with most decors while staying near invisible from eye level.
• Three strong neodymium magnets provide quick, tool-free attachment to metal vent registers.
• 1.5 mm thick construction adds stiffness and durability for repeated use and seasonal changes.

Beyond function, the BESWEL extender is designed to feel integrated into your room. The translucent plastic offers a barely-there presence, letting your furniture and flooring take center stage. It’s simple to remove or reposition, making it a practical option when rearranging a living room or guest space. This flexible solution aligns with everyday life, not a fixed fixture.
