Important Note: When it comes to buying 18x24x1 MERV 11 air filter, measure your filter dimensions to find the correct size filter. The size labeled on the filter packages is the ‘nominal’ size, which is a bit greater than the actual size. Example, if the ‘nominal’ size of the filter is 18x24x1, then the ‘actual’ size is 17.5×23.5×0.75
