Oxygen Concentrator Parts & Accessoris

What Needs Cleaning and Replacing, and How Often

The filters are the part to pay attention to. They are what stands between the compressor and a lungful of household dust, and they are the single biggest factor in how long a concentrator lasts. The P2-TOC uses two different felts on two different schedules — felt 1 sits outermost and takes the brunt, so it needs the more frequent attention of the pair, while felt 2 catches what gets through and is easy to forget precisely because it stays cleaner. The P2-E models use a single felt of their own, which is not interchangeable with either.

Filters are rinsed, dried completely and refitted — never put a damp filter back into the machine. Cannulas are replaced rather than washed. Batteries and sieve beds both carry a twelve-month warranty; if oxygen purity alerts start appearing, that is a conversation to have with us rather than a part to order.

None of this is onerous — a concentrator asks far less maintenance than most people expect. But it is worth keeping one spare of each consumable in the cupboard rather than ordering when you run out, particularly if you are travelling.

Just bought a P2-E? It ships with a single nasal cannula, which is roughly a month's use. The P2-TOC comes with twelve. Worth adding a supply now rather than in four weeks.

Finding the Right Part

Some Kingon parts are shared across the range and some are not, and the intake filters are the ones that catch people out. The P2-E, P2-E6 and P2-E7 all take the same single filter felt, CP2FF5. The larger P2-TOC takes two different felts, FI-T001 and FI-T002, and neither is interchangeable with the P2-E part.

Cannulas and tubing use standard connectors and fit across the range. Batteries are model-specific — check yours before ordering.

Your model number is printed on the label on the base of the machine, and filtering this page by model is the quickest way to narrow things down. If you are buying for someone else and cannot get to the label, ring us. Sending the wrong filter helps nobody, and it takes thirty seconds to confirm.

Frequently Asked Questions

Can I use a generic nasal cannula?

Standard cannulas share a common connector and will physically fit, but length and internal bore both affect delivered oxygen — particularly on a pulse dose machine, where the device is timing a burst to your breath. If you use a longer cannula or add extension tubing, tell your prescriber, because it can change what actually reaches you.

How do I know when the intake filter needs changing?

Go by the schedule in the table first — on the P2-TOC that is six months for felt 1 and twelve for felt 2 — but bring it forward if it looks like it needs it. A filter that has gone grey or grey-brown, or that no longer springs back when pressed, has done its job regardless of the calendar. Check more often if you have pets, run the machine in a dusty environment, or notice the concentrator sounding like it is working harder than usual.

Can I use a P2-TOC filter in a P2-E, or the other way around?

No. The P2-E, P2-E6 and P2-E7 share one filter felt (CP2FF5) between them, and the P2-TOC uses two entirely different ones (FI-T001 and FI-T002). They are not interchangeable in either direction. Running a concentrator with the wrong filter, or none at all, lets dust reach the compressor and the sieve beds — which is the expensive end of the machine.

Do I need a spare battery?

Every Kingon concentrator ships with two, which for most people covers a normal day out. A third is worth having if you regularly spend long days away from power, or if your prescribed setting is at the upper end of the range — runtime falls steeply as the setting rises, so a setting of 5 or above eats batteries considerably faster than a setting of 1.

Are these parts covered by warranty?

Batteries and sieve beds carry a twelve-month warranty. Consumables such as cannulas, filters and tubing are wear items and are not covered, which is as it should be — they are designed to be replaced. Full details are in our warranty policy.
