Great product, Poor delivery!

Great product been using them for years. Delivery by UPS however was terrible. Filter came in a box twice its size, all banged up. Top was lose, and the external white pre-filter was completely black. Banged around so much in transit it was covered in a very thick black lawyer of soot, inside and out. As a result its blowing soot all over instead of filtering the air. To large to return. Just hoping it stops blowing soot...
