The Filter Slot Seal is ideal for any furnace, air conditioner or air cleaner filter. Based on recommendations by the Department of Energy, you should cover and seal your filter slots in order to prevent air leaks. In addition to preventing air leakage from around the filter, it also prevents dangerous chemicals, particulates, allergens, carbon monoxide and other contaminants from bypassing the filter. This product includes two overlapping pieces of flexible vinyl. It uses magnets to form an attachment to the metal ducts around the filter. Reusable, the Slot Seal allows the filter to work efficiently. Your indoor air remains cleaner and healthier when you apply this tight-fitting and secure product. For greater efficiency and protection, use Slot Seal on your furnace, air conditioner and air cleaner filters.

Save Your Furnace Tip #3:
Did you know that the nominal size of your air filter is probably not the same as the actual size? Just like measurements on lumber, the actual size of an air filter is usually slightly smaller than the nominal size.
