Review on Accumulair Titanium 13 5X23 5 Efficiency Reduction by Neil Biondo

I made a mistake ordering this item, I didn't read the item description, without to note that it is an item rather than a combination. That being said I would do a test purchase by going to a local hardware store where I could buy 2 filters instead of one. My fault for not wanting to deal with the spacing advice and thought it would be easier!
