These are clear PET sheets with nano adhesive backing that stick over wall, floor, ceiling or RV vents to block airflow from unused registers. The transparent material keeps the vent looking close to normal, and the sheets can be trimmed with scissors to fit odd sizes. They suit renters and RV owners who want to shut off a vent without tools or permanent changes. Against magnetic vent covers, they stick to wood, plastic and aluminum frames that magnets won't hold, but they are adhesive-only and not reusable the way magnetic covers are.

These clear vent covers block off unused air vents. They are made from transparent PET, which resists tearing and abrasion during repeated daily use. The clear look blends in with indoor decor.
Each cover has a nano adhesive backing, so it attaches to smooth surfaces without tools or hardware. The sheet can be repositioned during installation to fine-tune alignment. The soft, bendable sheet can be trimmed to fit irregular or non-standard vent sizes.
Covering an unused vent redirects cool air and heat to the spaces you use more. It also helps keep odors such as cooking fumes and cigarette smoke from spreading between rooms. The covers work on wall, floor and ceiling vents in homes and in RV ventilation systems, and fit wood, plastic, iron and aluminum vent frames.
