Fart-filtering underwear converts odor-causing gas (and other unwanted scents) into odorless salts as it passes through the fabric. The underwear uses an innovative embedded electrostatic odor-neutralizing treatment that targets the molecules responsible for foul odors. A quick wash re-reverses the electrostatic charge to renew the fabric for more keister coughs.

Shinesty’s fart-blocking underwear were co-developed with Swiss scientists at Livinguard Technologies who spent five years developing the odor-control technology. Its performance has been 3rd party verified by Intertek to neutralize up to 99% of odor.

The Science Behind The Black Magic

How your fart-proof undies stay fresh for up to 40 washes.

Step 1: Let You Bottom Burp Out Slow. You want contact with the fabric so the electrostatic attraction can take place.

Step 2: The Science Begins. Our tech creates an electrostatic charge that actively hunts down stink molecules and pulls them in. Think bug zapper. But for fart smells. ⚡️

Step 3: The Transformation Takes Place. Once trapped, those odor molecules don’t just hang around. They’re neutralized through a chemical reaction that converts them into odorless salts.

Step 4: Rinse & Repeat. A normal wash releases the neutralized salts and re-exposes the positive charges in the fabric so you can release in peace over and over and over again.

Gone are the days of masking your farts with charcoal filter underwear. These fart filters don’t need carbon filter pads, or frumpy activated carbon filter inserts in order to work. Our fart-filtering underwear uses electrostatic attraction to neutralize up to 99% of your fart’s odor.
