Living with IBS, Crohn's disease, colitis, or any condition that causes excessive wind isn't just physically uncomfortable — the social anxiety it creates can be just as debilitating. Avoiding restaurants, dreading meetings, worrying on public transport, thinking twice before every social situation. It shouldn't have to be like that.
The Shreddies Carbonana is a discreet, portable flatulence filtering cushion that uses the same activated carbon technology originally developed for chemical warfare protection suits — now applied to give people with bowel and digestive conditions their freedom back.
It fits discreetly between the buttocks, works the moment you sit down, and neutralises odours before they can escape. Nobody knows you're wearing it. You stop worrying. You get on with your day.
The technology behind it
Shreddies' patented activated carbon cloth is cutting-edge textile technology. Due to the carbon's highly porous nature, foul-smelling gases that pass through it become trapped and neutralised on contact. The cloth reactivates every time it is washed, remaining effective for the life of the product.
This isn't a deodorant mask or a fragrance cover-up. It eliminates odour at source.
The evidence backs it up. Research published in The American Journal of Gastroenterology found activated carbon underwear to be the most effective method of removing flatulence odours. Independent testing by De Montfort University, presented at the 86th Textile Institute World Conference, found that the fabric:
"The fabric was found to remove sulphide and ethyl mercaptan so effectively that it can filter odours 200 times the strength of the average flatus emission."
— De Montfort University, 86th Textile Institute World Conference
Two hundred times. That's not a marginal improvement — that's complete, reliable odour elimination for even the most severe symptoms.
Who it is for
Excessive, malodorous wind is a common and deeply distressing symptom of many conditions. The Carbonana is designed specifically for people living with:
- Irritable Bowel Syndrome (IBS)
- Crohn's disease
- Ulcerative colitis
- Coeliac disease
- Diverticular disease
- Dyspepsia and gastritis
- Food intolerances — lactose, gluten, and others
- Post-bowel surgery digestive changes
- Gastric bypass and bariatric surgery
- Any digestive disorder causing excessive or malodorous wind
It is also worth knowing that anxiety itself can make symptoms worse — the chemical changes stress creates in the body directly affect digestion and can exacerbate any existing condition. Simply knowing you are protected can break that cycle. In many cases, not having to worry about wind is as beneficial as the filtration itself.
How to use the Carbonana
The Carbonana's ergonomic banana shape — 20cm x 3cm x 5cm — is designed to sit comfortably between the buttocks, positioning the activated carbon panel exactly where it needs to be. Once in place, flatulence passes through the carbon cloth before it can escape, eliminating odour instantly and completely.
For best results, ensure the cushion sits snugly without gaps. When sitting, keep knees together so that gas passes through the carbon panel rather than escaping around it.

- On public transport — sit with confidence, no repositioning, no adjusting, no anxiety
- In social situations — restaurants, cinemas, meetings — wherever you've previously felt anxious, the Carbonana removes the worry entirely
