{"title":"PerfectO2","description":"\u003ch1\u003ePerfectO2 Filters \u0026amp; Oxygen Concentrator Parts\u003c\/h1\u003e\n\u003cp\u003eKeeping an oxygen concentrator running cleanly and quietly comes down to one often-overlooked detail: the filter. The PerfectO2 line from Sunset Healthcare provides replacement filters engineered to fit Invacare Perfect O2 concentrators, so patients and caregivers can maintain proper airflow and consistent oxygen output without hunting for exact-match parts.\u003c\/p\u003e\n\n\u003cp\u003eAt the center of this collection is the \u003cstrong\u003eSunset Healthcare PerfectO2 Cabinet Filter (OF9004)\u003c\/strong\u003e, a foam cabinet filter measuring 1\/2 x 3-3\/4 x 6-7\/8 inches and sized specifically for the Invacare Perfect O2. The cabinet filter is the first line of defense against dust, lint, and airborne particles being drawn into the unit. When it clogs, the concentrator works harder, runs warmer, and can struggle to hold its purity level — which is why routine replacement matters more than most people realize.\u003c\/p\u003e\n\n\u003cp\u003eHow often should you swap it out? Most cabinet foam filters should be checked weekly, rinsed and dried if reusable per the manufacturer's guidance, and replaced when they become discolored, brittle, or difficult to clean. Homes with pets, dust, or heavy daily use will go through them faster. Keeping a spare on hand means you're never forced to run the machine on a dirty filter while you wait for a shipment.\u003c\/p\u003e\n\n\u003cp\u003eBecause this is a fit-specific foam filter, confirm your concentrator is an Invacare Perfect O2 model before ordering — the OF9004 is designed for that unit's cabinet housing.
