NasalGuard Inventor was Inspired to Prevent Daughter's Cat Allergies

About 20 years ago, New Jersey resident Ashok Wahi's daughter Aikta frequently suffered from allergies after exposure to her friend's cat. He wanted her to be relieved from the constant sneezing, runny nose, and congestion without taking drugs. When conventional over-the-counter remedies made her sleepy at school, he was motivated to create a drug-free solution for his daughter's cat allergies that would not cause drowsiness and other side effects.

The project's goal was to prevent the inhalation of allergens rather than treating the allergy symptoms after the fact.

With this in mind, Wahi put his engineering skills to work and developed a unique gel that blocks allergens on contact, therefore alleviating allergy symptoms causes by pet dander (cat dander, dog dander, and other animal dander). Hence the birth of NasalGuard ® Technology. And NasalGuard AllergieBLOCK Gel has been clinically proven to block not only pet dander, but also other airborne allergens like pollen, ragweed, dust mites and house dust.
