The Revitalizaire Magnetic Vent Covers include 12 powerful neodymium magnets to ensure a tight seal for all applications.
Floor Registers: Usually no magnets required unless very strong airflows are present. For these cases, 1 magnet per cover, located in the center should do the trick.
Wall or Ceiling Registers: Either 2 or 4 magnets will be required per cover. This will depend on the amount of metal surface area of your register as well as airflows. Sometimes only two magnets are required when they are placed at opposite ends of the covers. When four magnets are required, one should be placed in each corner.
Cover Dimensions: 8″ x 15″ x .04″
Neodymium Magnet Dimensions: 1.3″ x 1.3″ x .08″
Package Includes: three (3) magnetic rubber sheets and twelve (12) neodymium magnets.
If our product fails to maintain a seal on your register, we will refund your purchase in full.
NOTE: Revitalizaire Magnetic Vent Covers are intended for metal registers only. Do not cover more than 50% of your home or office’s vents and do not cover return air intakes. Doing so could cause damage your ventilation system.
Neodymium magnets are brittle by nature. Please be careful when handling these magnificent specimens.
