I purchased a subscription for periodic shipments of two 17.5 X 23.5 filters, but when the first shipment came, the filters were marked 18 X 24. OMG, I thought, but included was a note saying the filters were the correct size. And they were! Fit perfectly. Thanks, AirFilterBuy.com! Very convenient-no shopping at different stores for the odd size my A/C units take.

Build a Custom Size
Simply measure the length and width of your filter with a tape measure and choose the closest size
(to 1/8”) in the drop down menu. 1/8” tolerance is standard and should not cause a problem in any
standard filter application.
Please note that the ‘actual’ filter size, ie the size that your tape measure shows, should be used when
creating a filter with this tool, not a nominal filter size. Note that the depths of each filter are
standard, as shown to the right.
