Air conditioning and heaters use up a huge amount of energy. Most families’ heating and cooling expenses make up for about half of their total energy costs. During the summer and winter months, lots of people start looking for alternatives to their expensive heating and cooling units. Some people prefer fans or space heaters and others opt to close off some vents in closets or unused rooms. However, simply closing a vent doesn’t always stop the air flow completely. This is where magnetic vent covers step in to do the extra work.

By covering heat and air conditioner vents in unused rooms, you may be able to cut down on high electricity bills. Magnets cling to non-aluminum ducts vent covers, blocking 99% of the air flow. Standard Magnets work well for floor vents and wall vents while we recommend high energy magnets for ceiling vents. With a wide variety of colors and options available, vent covers can be customized to match your room and remain discrete.

Magnetic vent covers are available in many sizes, colors and materials, but you can save money by buying larger magnets and cutting them to size yourself. The magnetic sheeting cuts easily with scissors or a craft knife. Custom fit the magnets by cutting around vent control arms and mounting screws. More magnet surface in contact with the steel vent cover translates to more clinging power and greater efficiency with a better seal.

Standard magnets don’t work for ceiling vents due to the pressure created by the fan motor and the weight of the magnet itself. High energy flexible magnets are made with stontium ferrite powder which has twice the magnetic pull as standard flexible magnets found in sign shops and box stores.
