You’ve likely used filters on Snapchat and Instagram to enhance your pictures or create funny photos for friends. But have you ever used filters for your underwear? Whether you’re familiar with this invention or not, fart-filtering underwear really does exist and has a very specific purpose – to absorb and neutralize the unwanted aroma of your farts.
Keep reading to learn the science behind fart-filtering underwear, if it really works, and how to use it.
What Is Fart-Filtering Underwear?
As the name suggests, these undergarments are designed to filter your flatulence by capturing odor particles and lessening the blow of your butt bombs. At the time of this writing, one company reigns supreme when it comes to producing fart-filtering underwear – Shreddies. Using a charcoal lining, similar to the filters used on airplanes to filter out offensive odors, this innovative product was launched in the late 2000s by UK product designer Paul O’Leary.
Available for both men and women, the carbon-lined back panel of these boxers and briefs is designed to remove any unpleasant odors that escape your back door. The lining captures and neutralizes foul-smelling fragrances expelled from your body before the particles reach the air and the noses of your neighbors. The flatulence-filtering underwear’s carbon fibers are reactivated after every wash and ready to use again, protecting you and those nearby from embarrassment and exposure to unpleasant odors.
The Design and Invention
O’Leary got the idea for fart-filtering underwear after suffering from stomach issues that made it difficult for him to attend work, socialize, or leave the house. The designer was plagued by constant and foul-smelling farts that were both mortifying and inconvenient. After years of isolation and aggravation, O’Leary decided it was time to develop a solution to his problem.
He started by contacting textile designers from around the world in the hopes of fabricating a material that would achieve his dreams. A team of scientists at DeMontfort University tested the carbon material that O’Leary was proposing and helped the inventor secure the final patent on his one-of-a-kind underwear.
The activated carbon cloth on a pair of Shreddies is nestled comfortably between two layers of soft jersey fabric, creating an inconspicuous barrier between your farts and the outside world. The carbon cloth is so powerful that it was once used in chemical warfare to protect emergency service personnel from harmful toxins and gases. That’s one reason why the gasses expelled from the wearer’s backside are no match for this powerful product.
Fast forward to the present day, and Shreddies produces a variety of products for both men and women and has won several awards. The underwear is wildly popular among those with gastrointestinal issues, including:
- IBS
- Crohn’s Disease
- Colitis
- Gastritis
- Dyspepsia
- Food intolerances
You don’t need a diagnosed intestinal issue to purchase flatulence-filtering underwear or enjoy its benefits. Anyone looking to reduce the offensive odors coming from their rear end can take advantage of these innovative undergarments.
