Comments about Koch Filter Corporation 12" X 36" X 1" MERV 13 Pleated Filter:

I was happy to find that discountfilters.com stocked the correct size for my oddly shaped main filter intake duct. Their price for filters of a comparable Merv rating saved quite a bit over the normal big box home store products that i normally buy, even with shipping. My big problem with the store-bought filters, aside form the inflated pricing, was that i had to buy three 12x12s because they don't carry the 12x36 that i need-that's annoying. Shipping from discountfilters.com was quick and the products arrived in good shape. My only concern is that the filter's physical dimensions did not completely cover the opening and were short approximately 1/2 an inch. This gap generated a whistle. I fixed the issue with some weatherstripping, and while it would be nice for the filter to fit perfectly without it, the fact that i can get a quality filter in my (somewhat) correct size and for a great price is worth it.
