Don't know your model? Measure instead
Measure the filter itself, not the slot. Round each dimension up to the nearest whole inch — that rounded figure is the nominal size printed on replacement filters.
Nominal vs actual, in one line
A filter labelled 16x25x1 actually measures about 15.5 x 24.5 x 0.75 inches. The label is rounded so the filter slides into the slot without binding. Always order by the nominal (rounded) size.
