Please DO NOT PURCHASE to cut the cover if your vent falls out of our size ranges (it will damage the cover’s features and will not work).

☑️🧲 INNOVATIVE DESIGN WITH EXTREMELY STRONG MAGNETS – New & innovative *Patent pending* magnetic vent covers (3 pack) – The only covers on the market that will never fall off, even on ceiling vents with maximum possible airflow! We engineered a special design with powerful hidden “Rare Earth” neodymium magnets and a unique backside pocket that will cover the vent screws and dampers perfectly. Once installed, this cover will never move, shift or fall off of your vent.

☑️⛔🧊 COMPLETELY BLOCK COLD/HOT AIRFLOW IN SPECIFIC ROOMS OR AREAS – At last, a magnetic vent cover that actually works! It completely prevents hot or cold airflow in specific rooms (where the dampers do not work properly or don’t exist). No more freezing rooms with really cold air blowing at you while sleeping and no more hot rooms that feel like a sauna. In addition, it will also help with annoying noises (like loud music) or unwanted smells (like smoking or cooking) from neighbors in apartment buildings.

☑️ 🏠 🌡️ IT IS SUPER EASY TO INSTALL & WILL BOOST THE AIRFLOW IN OTHER ROOMS – Once the magnetic vent covers are installed in unoccupied rooms (like basements), the airflow in other rooms will significantly increase. This is a simple and cost-effective solution that takes minutes. Simply follow our step-by-step included instructions and use the sturdy box to store covers that are not currently in use. The magnetic covers will work on any vent that matches the cover size ranges.

📏 PLEASE CONFIRM YOUR VENT SIZE & CHECK MAGNETISM – Unlike other flimsy one-size-fit all magnetic vent covers, we have created a unique cover design for each vent size. Each cover is designed with a different backside pocket feature and specific locations of hidden magnets. First, check that your vent is magnetic. Second, this cover WILL ONLY work on vents with a width between the range of 7.25” to 8” and length between the range of 13.25” to 14”.
