Consumables · UK stock
A fresh cannula each month. A fresh filter every six months. Both held in UK stock, both delivered free the next working day. Your daily practice carries on without a pause.
The small parts
A hydrogen machine is a quietly simple thing. The generator does its work for years. The only parts you replace are the two that sit in the path of the gas: the nasal cannula you wear, and the filter inside the machine.
A fresh cannula once a month. A fresh filter every six months. Both held in UK stock, both delivered free the next working day, both fitted for every H2 Pure Life machine we sell.
Two small parts. A simple rhythm. Nothing more to think about.
Lasts four months
Silicone · pack of four
£30
Four silicone replacement cannulas in a single box — enough to keep your daily practice fresh for four months. Soft, skin-friendly silicone, the comfortable under-ear loop, and the standard connector that fits every H2 Pure Life machine.
Lasts ten months
Latex-free · pack of ten
£35
Ten replacement cannulas made without latex, for anyone with a known sensitivity or a simple preference to avoid it. Same soft feel, same standard connector, same fit. Roughly ten months of daily practice in one parcel.
Lasts one year
Filter · pack of two
£50
The internal filter is a quiet workhorse — it sits inside the machine and keeps the air clean before electrolysis begins. One filter fits every H2 Pure Life machine. Replaced every six months, a pack of two is simply a year's supply, quietly put away until you need it.
When to replace
The two parts run to different rhythms. The cannula, which sits against the skin, is refreshed monthly. The filter, tucked inside the machine, is refreshed every six months. Gentle cues to keep in the back of your mind — nothing more.

The daily practice
The beauty of a hydrogen practice is that it asks very little of you. A reliable machine. A soft cannula. A working filter. A comfortable chair. Everything else — the reading, the working, the slow cup of something — is already yours.
The year's supply
Three packs of four silicone cannulas and one pack of two replacement filters, delivered together — a full year of consumables in a single parcel.
£120
A small saving — but mostly, one less thing to remember.
Frequently asked
Once a month. Daily use gradually softens the tubing and the fit relaxes a little. The pack of four covers four months in one parcel, and the latex-free pack of ten covers roughly ten — both quietly put away in a drawer until the first of each month.
Yes. The same standard connector fits the Hydro Gen, the Hydro Nova, and the Hydro Medic. There is one cannula type and one filter type across the whole range — by design, to keep ordering simple.
Gentle wiping between sessions is fine and we'd encourage it. The cannula is designed as a consumable, though — think of it like a toothbrush head. The fit, the surface, and the experience of a fresh one are all noticeably better.
Order by 2pm on a working day and it usually arrives the next working day, free anywhere in the UK. Held in UK stock — no three-week waits from overseas marketplaces.
Two reasons. The first is fit — generic cannulas and filters from third-party marketplaces vary in connector size, tubing softness, and material spec, and a poor fit is the difference between a comfortable session and a fiddly one. The second is provenance. Our consumables are sourced to a single specification, held in UK stock, and shipped from the UK with full support behind them. If something isn't right, you have a UK team to call.
It is supplied clean and individually sealed. It isn't sterilised in the medical sense — it doesn't need to be, as it sits at the nostrils and against the skin rather than inside the body. Wipe gently before first use if you'd like to.
Silicone is the default standard option and what most owners use. The latex-free pack exists for anyone with a known latex sensitivity, or simply a preference to avoid it. Fit and comfort are equivalent — the difference is in the material.
It takes about a minute and requires no tools. Every machine ships with a short video showing the exact steps, and the UK team is happy to walk you through it on the phone if you'd rather see it done together the first time.
Unopened packs can be returned within 30 days for a full refund. Once a hygiene seal has been broken, the pack can't go back into stock — but if anything is wrong with the product itself, contact the UK team and we'll put it right.
A note from Phil
Three years in, I still notice the difference the morning after I swap to a new cannula. It's not dramatic. It's not life-changing. It's just that the fit settles back into place, the tubing doesn't remember the shape of yesterday, and the whole session feels a fraction cleaner than the one before it.
That's why we hold them in UK stock, ship them free, and — when you'd rather not think about it at all — put twelve of them in a single box with the year's filters alongside. We don't sell singles, because a single doesn't quite cover the way the practice actually works. A small thing, looked after properly.
