Fujitsu Mini Split & Ductless Air Filters

Genuine OEM replacement filters for Fujitsu Halcyon and Airstage mini splits — wall-mounted ASU, ASUA, ASUB, ASUG and ASUH units, AGU floor consoles, and ABU and AUU ceiling and cassette units. Choose from washable main filters, Apple Catechin and deodorizing filters, and annual filter bundles. Every listing names the exact indoor unit models it fits.

Find your model number on the nameplate sticker on your indoor unit, typically on the right-hand side of the unit or on the bottom edge facing the floor, then search it above. Not sure? Send us your model number or a nameplate photo and we'll match the right part.

Most in-stock orders ship within 1 business day, and replacement filters are backed by our Compatibility Guarantee. Also see our mini split filter buying guide and the Fujitsu Airstage UTY-TFSXH4 WiFi adapter.
