Important Note: Almost ALL furnace filters have a different “actual size” than the nominal size printed on the air filter. With 4″ and 5″ air filters, there is often a wider variance depending on the manufacturer. Nordic Pure Honeywell Replacement MERV 10 filters are traditional 5″ filters with an actual depth of 4 3/8″. Always measure your current filter or housing to ensure the actual size matches the filter you are ordering. Proper sizing is crucial for optimal HVAC performance.
