Seems OK, but can't prove it
The form and fit were good.  The delivery was prompt.  The only concern was that there was no MERV 11 marking on the filters.  Other filters that I have bought from my HVAC contractor have a MERV 11 certification on the filter.  The only thing that stated MERV 11 compliance was on the external shipping box label, so who knows what the MERV level of the actual contents really were.
