"I recently moved to a new place and was surprised that the HVAC system used non-standard sized filters.
I admit that I carefully measured the filter sized that we needed and found that it was even different than what was supplied with the unit. I order the custom sized filters, they were shipped and received on time as promised.
I immediately installed one of the the filters and it fit perfectly!"
