SEAL360 Magnetic Vent Covers 2-Pack - Complete Seal for 7.5 x 16 in

Our review of the SEAL360 Magnetic Vent Covers focuses on homeowners and RV owners looking to control HVAC airflow without tools or permanent changes. The bottom line: these magnetic covers create a tight, gap-free seal against steel vent faces so you can block air in unused rooms or boost flow to occupied spaces, helping reduce heating and cooling waste. Installation is simple, and the magnet strength means the covers stay put while still being removable, which makes them a practical, low-effort way to save energy.

Key Features

• Complete seal: The cover conforms to the vent damper and creates no air gaps, preventing unwanted airflow through closed vents.
• Magnetic fit: Strong magnets adhere to steel vent faces so the cover stays in place on walls, floors, or ceilings without hardware.
• Size specific: Designed for steel vent faces sized 7.5 to 7.75 in wide and 15.5 to 16 in long to ensure a secure fit when measured correctly.
• Energy control: By blocking air in unoccupied rooms and boosting flow to others, the covers help reduce heating and cooling costs.
• Removable and adjustable: Covers are easy to install, remove, and trim for a better fit around registers or obstructions.

Who It's For

These vent covers are best for people with steel HVAC registers in homes, apartments, or RVs who want a nonpermanent way to redirect or stop airflow. They suit renters who cannot alter ducts, homeowners who want quick seasonal control, and RV owners seeking simple climate management without tools.

Those who should look elsewhere include owners of plastic or nonmagnetic vent faces and anyone with vents outside the stated size range; measuring the vent face is essential before ordering to ensure the seal works as intended.

Pros & Cons

Pros

• Strong magnets provide a secure hold and make installation painless.
• The cover conforms to the vent damper, delivering a true complete seal rather than a loose cover.
• Effective at reducing airflow to unused rooms, which can lower energy use when used correctly.
• Durable construction that can be trimmed for a customized fit and repeated use.

Cons

• Only works on steel vent faces within the 7.5 to 7.75 by 15.5 to 16 in size range, so measuring is mandatory.
• Not compatible with nonmetallic or very ornate vent grilles where magnets will not stick.
