The filters are ok , quality is very good, the only problem that I have is that the filter that my furnace uses is 16x25x4 the ones I received are smaller. Still working but I have to do some adjustments.

Do not send me anymore filters unless I call you. I let my repairman order and he ordered incorrectly.

They seem to work fine,, for the all of two weeks they have been installed. No complaints except for the constant asks for a review on a product not fully used yet
