I purchased 4 of these last year but didn't create an acct. I didn't pay close attention but I thought the pleats were evenly spaced. These, that I purchased this year are not. The one that measured range from a1/2" to 1-1/2'. and they are placed in the frame crooked. I have an old flip phone and cannot provide you with pictures nor video. otherwise, a GREAT filter!!
