A: I don't know how a filter 1 inch longer would fit the opening, I would suggest tying with a less expensive filter first. If you are purchasing in person just verify you can return if it doesn't fit.
A: Thank you, Jatt, for your recent inquiry with The Home Depot. We apologize, we currently do not offer the Honeywell 17-1/2 x 29-1/2 x 1 Superior Allergen Pleated MERV 11 - FPR 9 Air Filter (203641919). Nor do we offer a filter in 17 in. x 29 in. x 1 in. We appreciate your business and look forward to serving you in the future.
