Upgrade airflow with a discreet vent extender

The RXSIAT Sideways Magnetic Vent Extender is a compact two-pack solution designed to sit just under furniture like sofas, dressers, chairs, desks, or beds. It subtly redirects air from floor vents into living spaces, helping you achieve more even comfort around seating areas. This model is patent-pending in the US (Invention Patent Pending US19/390,657).

What it fits and how it works

Designed to work with vents that are 3 to 6 inches wide, the extender slides over an existing vent opening without tools. Six strong neodymium magnets hold the piece in place over metal registers, so you can install quickly and securely. The extender supports 10-inch or 12-inch floor registers and stretches from nine inches to seventeen inches in length, with a modest height of about 1.7 inches.

Benefits you may notice

  • Enhanced air distribution: directs airflow toward seating and living areas for more consistent comfort.
  • Quiet, non-intrusive design: blends under furniture while maintaining airflow.
  • Space-saving and portable: easy to reposition in different rooms as needed.

Durability and ease of use

  • Durable plastic construction that resists wear and maintains shape over time.
  • Tool-free installation via magnets—just slide over the vent opening on metal registers.
  • Includes a practical 2-pack for multi-room setups or replacement in case of relocation.

Practical notes

To ensure proper use, confirm vent registers are metal. The magnets are designed for magnetic metal vents and may not grip non-metallic registers. Use as a supplementary airflow aid to support your existing HVAC system rather than a guaranteed cure for temperature differences.
