Not what I expected
In ordering a case of 4" filters I was never informed that it would take a Month or so to receive my order. I know there is a supply problem in the country but a heads-up would have been nice and understandable. The the filters were delivered while I was away visiting my family and I was lucky that I had a covered entrance that kept the filters from being rained on. The filters, while a nominal 24x24x4 were listed as an actual size of 23.375 x 23.375, what I received was 23.25 x 23.25. The end result was poor communication and no quality control.
