Genuine Daikin 1597259 Dust Collecting Element Frame is the frame that holds the dust-collecting element which traps fine dust electrostatically as air moves through the indoor unit. A cracked or distorted frame stops the element seating and sealing as it should, letting dust bypass. The genuine frame matches the unit exactly, holding the element square where a generic part can sit loose. Supplied as the frame only — the dust-collecting filter element is not included.
