“I fly transatlantic twice a month and NasalGuard is now part of my travel routine. A small amount around the outside of my nostrils and above the upper lip, and you genuinely cannot see it. An easy barrier step before a crowded flight.”

An invisible, drug-free gel barrier you apply around the outside of your nose before boarding. Built on our positive ion barrier technology, NasalGuard For Air Travelers goes on in seconds and helps block airborne dust, mold, and other particles in recycled cabin air, an easy addition to your routine before every flight, train ride, or trip through a crowded airport.
NasalGuard For Air Travelers is a drug-free gel that goes on invisibly and starts working immediately: no waiting, no residue, no interruption to your travel routine.
Creates a positive ion field around the nostrils that helps trap and hold airborne dust, mold spores, and other microparticles before they reach your nose.
The 3g tube is sized for carry-ons and clears airport security easily, so it’s ready whenever your trip is.
Zero known interactions with medications. Non-drowsy and non-irritating. Safe for adults and children. Applied externally around the nose, so nothing is inhaled or absorbed.
Glycerin, hydroxyethyl cellulose, deionized water USP, dimethicone, also contains non toxic, cosmetic-grade preservatives and emulsifiers.
NasalGuard is built on one idea: an invisible barrier that fits into the moment you actually need it. Positive ion barrier technology sits externally, around the outside of the nostrils and above the upper lip, designed to help reduce inhalation of everyday airborne particles like dust, pollen, and pet dander.
We keep the formula drug-free and the application simple: a small amount, applied in seconds, ready before your commute, your flight, or your next visit somewhere dusty. No deep-nasal insertion, no complicated routine, just a barrier step you can carry anywhere.

“We flew Denver to London with two kids. There's no smell and it's invisible, so the kids didn't mind it at all. A simple, drug-free barrier step for shared-air travel.”

“During pollen season I add NasalGuard before my morning walk. I like that it's a drug-free barrier I apply around the outside of my nose — a simple step for time outdoors.”

“What sold me is how simple it is. Place a small amount on a fingertip, spread it between thumb and finger, and apply around the outside of the nostrils and above the upper lip. Completely invisible once it's on.”
