Shreddies Flatulence Filtering underwear is manufactured with love in the UK using the best materials to ensure the highest standards. 

How do they work? 

Shreddies flatulence filtering underwear features a ‘Zorflex’ activated carbon back panel that absorbs all flatulence odours. Due to its highly porous nature, the odour vapours become trapped and neutralised by the cloth, which is then reactivated by simply washing the garment. Previous research published in The American Journal of Gastroenterology found activated carbon underwear to be the most effective method of removing flatulence odors. The underwear has gone through rigorous testing, and findings from research by De Montfort University were presented at the 86th Textile Institute World Conference; the fabric “was found to remove sulphide and ethyl mercaptan so effectively that it can filter odors 200 times the strength of the average flatus emission." The fabric remains effective for the life of the garment (2 - 3 years) providing the care instructions are followed correctly. The Shreddies motto is ‘Fart with confidence’ and our underwear ensures just that.

Who are Shreddies For?

Shreddies can be worn by anyone but they offer a perfect solution for sufferers of IBS (irritable bowel syndrome), gastritis, Crohn’s disease, Dyspepsia and Colitis as well as food intolerances and many other bowel and digestive disorders. Anybody that suffers from excessive flatulence will know of the social issues that it can cause and Shreddies not only improves the physical symptoms but also helps reduce the anxiety associated with this condition.

In many cases, simply not having to worry about flatulence can help improve a persons condition. Anxiety can create chemical changes in your body which can affect your digestive system, exacerbating a person’s condition. Here at Shreddies we believe that everybody should own a pair of these amazing undies. The average person passes wind 14 times per day so whether you’re a sufferer of a digestive disorder or just have flatulence, Shreddies can help. Our underwear is discreet, offering the wearer added assurance that nobody will be able to tell you are wearing anything other than regular underwear.

Shreddies have activated carbon cloth (called Zorflex) sandwiched between layers of regular fabric. The specialty layer absorbs and traps the odor before it can make its way out into the open.



Shreddies underwear are not magic, they work for a reason. If flatulence passes through the carbon filter all odour will be removed. How you stand or sit and how you pass flatulence all need consideration to get the most out of your underwear. Ensure there are no gaps around the waistband or leg openings and the fit is taut against the skin. 

To avoid flatulence escaping around the filter we recommend that you stand with your legs together and try to let your wind out slowly. When sitting, keep your knees together so that flatulence escapes through the rear panel. If your Shreddies fit correctly and you ensure that your flatulence passes through the rear panel all odour will be removed.
