Powerful Magnetic Vent Covers 2-Pack for 7.25in-8in x 15.25in-16in

Our review finds these magnetic vent covers best for homeowners and renters who need a fast, reversible way to seal unused floor, wall or ceiling registers. The main reason to buy is the upgraded design: hidden rare earth magnets and a backside pocket that hold the cover firmly over screws and dampers, so the covers "never fall off" even on ceiling vents. The pack is aimed at people who want to block unwanted drafts, noise and odors without cutting or permanently altering registers.

Key Features

• Size guidance: Choose from 26 sizes and colors and use the provided size chart to ensure a correct fit so the cover functions as intended.
• Patent-pending magnetic system: Hidden rare earth magnets provide a strong hold and keep the cover secure on vertical or overhead vents.
• Backside pocket design: A tailored pocket fits over screws and dampers to create a snug seal that resists slipping.
• Blocks airflow, noise and odors: The cover prevents unwanted hot or cold air, reduces noise transfer and helps minimize neighbor odors in apartments.
• Quick installation: The two-pack installs in minutes and can be removed and stored in the included box when not in use.
• Non-destructive use: The product is intended to be used without cutting or altering the cover to preserve magnet performance.

Who It's For

These magnetic vent covers suit apartment dwellers and homeowners who want a temporary, non-permanent way to block registers in unused rooms, basements or garages. They are particularly useful for anyone seeking to redirect HVAC airflow to occupied areas or to reduce drafts from ceiling vents.

They are not appropriate for non-magnetic vent materials or for vents outside the specified size range; do not cut the cover to make it fit. If a vent is larger or smaller than the 7.25in-8in width and 15.25in-16in length ranges, buy a different size from the available options instead.
