Sizes are incorrectly labeled

Ordered 12x24x1 but then when it arrives the"actual size" is like 1/4" smaller. Just make it the correct size or indicate "actual size" before I buy. Waste of time

I have very odd and small size return air grills in a condo in Miami Beach. NOBODY has a filter available but Filterbuy comes through every time with high quality and high MERV custom built filters. Keep up the good work!

I have an odd size HVAC return and they fit perfectly. One of our kids has asthma and the monthly delivery makes it impossible to overlook the filter change.
