Title: Buyer Beware
Review: This product is about the same as a CHEAP furnace filter that you could purchase from Home Depot or Lowes for much less. If you're like me you purchased your Filtrete Air Purifier for almost HEPA properties. Make sure that when you order, you order Genuine 3M replacement and not "Aftermarket"...if you do order this aftermarket product, you will not be satisfied as it only has maybe 25% to 30% of the filter media as the 3M.
