  1. 1.0 out of 5 stars

    sizing

    i bought these annually because of their ACTUAL 14x20x1 sizing, were framed with white cardboard and printed 14x20x1 "actual" size. well, last box is brown cardboard framed and NOT marked at all. they now collapse and fall into my duct work. no size marked on box so they are now nominal sized...meaning 13.5 x19.5x1? very weak compared to the white framed so the brown cardboard is less sturdy. i'll buy if i can't find better...but not if i can find Actual sized elsewhere. DISAPPOINTED by DOIT!
