New filter design began production for models sold starting in 2018 and should fit all the new 4375W / 3500W model # 63962 and 63963. I *strongly* recommend you physically inspect filter prior to ordering to see what Harbor Freight used in your model.
Filter measures approximately 4.25" x 4.25" and 20mm thick.
