      The filter keeps our heat pump safe from the dirt/dust/dander of several dogs.

        Comments about Koch Filter Corporation 20" X 30" X 1" MERV 11 Pleated Filter:

        We began ordering these filters when my son, who is an architect, told me about this company. He researched when designing and building his own home that they have many sizes to choose from. They also send me emails to remind me when it is time to change the filter- which is extremely helpful! Other companies will tell you to tape two or three other filters together, and or place them side by side, but this company had the odd size we needed. They are pleated and extremely easy to install, but they are kind of expensive.

            The filter media was fine. The price was right. Some of the filters were damaged when I opened the box. The edges were flatened. Not worth returning them. I repaired with duct tape.

                Equal quality for similar priced products.
                May present problems for some since product runs smaller than any other product we have used in this size.

                  These filters are well constructed and properly sized. Have no air leakage around the filters or whistling noises when the house air blower engages.
