Good product wrong size

Comments:

Although my filter stated 18" x18" x1" in actuality it measured 18"x14"x1", leaving an overhang by 4". Too large for the filyer to fit tight..

BOTTOM LINE: Yes, I recommend this product

18x18 permanent filter

Comments:

The filter looks good. Arrived very slightly damaged - not enough to affect function, and appearance doesnt matter - filter goes inside furnace, out of sight. Damage is shippers responsibility, not Discount Filters. discount Filters.

BOTTOM LINE: Yes, I recommend this product
