Description
The Sunset PerfectO2 Foam Cabinet Filter is the foam cabinet filter for the Invacare PerfectO2 oxygen concentrator, cut to the machine's cabinet size of 7 in by 3 3/4 in by 1/2 in. It matches Invacare OEM number 1143492, so the replacement drops into the cabinet the machine was built with.
- Cut to Cabinet Size – The foam is sized 7 in x 3 3/4 in x 1/2 in for the PerfectO2 cabinet, with no trimming to fit.
- OEM Number Match – It corresponds to Invacare OEM 1143492, the cabinet filter the machine specifies.
- Foam Intake Filtration – The foam filter screens the air entering the concentrator cabinet, the first filter in the machine's air path.
The Cabinet Filter the PerfectO2 Was Built With
Concentrator maintenance starts at the cabinet filter, because it is the screen every litre of intake air crosses before the machine does its work. This foam filter is cut to the PerfectO2's cabinet dimensions, 7 in by 3 3/4 in by 1/2 in, so it seats in the cabinet recess as the original did. Sunset publishes the Invacare OEM reference 1143492 for the OF9004, which lets biomed and home-care providers cross the part directly against the machine's documentation. Cabinet filters are a scheduled replacement on concentrator service, and a foam filter at this size is a quick swap during routine maintenance. For providers running PerfectO2 fleets, stocking the cabinet filter by its OEM number keeps the right part on the shelf.

Why the Cabinet Filter Is a Scheduled Part
Intake air is unfiltered room air until this foam screen stops it, and a loaded cabinet filter makes the whole machine work harder. A cut-to-size replacement keeps that maintenance to a quick swap.
- Exact Cabinet Cut – The foam matches the PerfectO2 cabinet dimensions – it seats without trimming – filter changes take moments.
- OEM Cross on Record – The 1143492 reference is published by Sunset – the part crosses directly to the machine's documentation – ordering errors drop.
- First Screen in the Path – Cabinet filtration screens intake air first – the machine's internals stay cleaner – service intervals hold their rhythm.
