My issue is fit. I bought 16" wide and these are almost a quarter inch more and I had to force the filter in the furnace holder. Not a good fit. Quality seems ok.
The filters are only 3/4 of inch. All the filters I have bought from different brands the filter was 7/8 of inch or greater. This concerns me . Since you say it's one inch and it's not. Why is this? You do have nice filters, I do want thicker filters. What is thickness of a 2-in filter?
