Be sure you have measured your existing filter before placing an order, some manufacturers undercut filters so you should never base it off the label. Exact/custom filters are not eligible for returns or exchanges. Manufacturing tolerances of plus 0, minus 1/8" will be observed on overall width and length of filter. Picture is used as a reference, sizes will vary. Filters larger than 25x30x1 are considered a double filter where there is additional strength down the middle of the filter. It's our policy to list the smallest dimension first. When the filters arrive the label will be displayed as such, this will not impact compatibility - it's just a matter of how you hold the filter.
