Quick and easy. The order at which I had to process my information seemed a little like it could have me go down a rabbit hole of getting regular deliveries if I wasn't careful.... as changing my filter varies greatly depending on the work being done in this warehouse. So replacement can be unpredictable.
On the website, I searched for York 5" filters, found what you listed as York filters and purchased them. The were too long and too thick (5 1/4"). York filters are 4 7/8" max. Filters appear cheaply made after I purchased Nordic Pure brand.
We recently replaced the Merv 13 Lennox replacement filter in our furnace. I've got to say, it sure does a great job cleaning the air we breathe in the house when you look at how filthy the filter was after 6 months! It made a believer out of us to always use a high Merv rated filter in the future.
