Although TRAVEL ITCH RADIO rarely promotes a particular product, NasalGuard is a notable exception. An airborne particle blocker that is non-invasive, drug-free, and easy to use, NasalGuard protects against allergies and airborne contaminants, both indoor and outdoor. Inventor Kanika Wahi, an engineer working in concert with her father Ashok, explains more when she visits the show Thursday, August 20, at 8p EDT. Listen live on iTunes or BlogTalkRadio.com as Dan Schlossberg and Maryellen Nugent-Lee conduct a live interview in the 380th episode of TRAVEL ITCH RADIO. Or check out the archived show later on the TRAVEL ITCH RADIO Facebook page.
