I don't know NordicPure but the 20x25x4 size does not fit the Honeywell FC100A 20x25x4 filter housing. He is too thin and especially not big enough. Falls out of the nest. The 20x25x4 filters from Filtrete and of course the Honeywell filters fit perfectly. After measuring the hole in the Honeywell filter housing and looking at the exact dimensions of the NordicPure 20x25x5 filter I decided to give it a try and indeed it fits perfectly. Assuming it is indeed a MERV 12 filter as advertised, the two filter bundle is a great deal.
