First Defense Nasal Screens (FDNS) are self-adhering nasal filters designed to help filter and reduce contaminates (allergens, airborne germs, noxious particles) inhaled by the user. They can be worn over the nostrils for up to 24 hours and are self-cleaning “so they will not clog” and seal 100% of the nasal passage. The latex-free, hypo-allergenic, non-visible product can be worn in the hot and cold and are one-size-fits-all.

When FDNS was pitched on Shark Tank in 2011 (Mark Cuban’s first season), FDNS inventor Joe Moore turned down a $4 million offer for the whole company from Robert Herjavec. Instead, Moore agreed to a deal with Cuban, Daymond John, and Kevin O’Leary — $750,000 for 30 percent equity and 10 percent royalty. But after the episode, the deal was not finalized.
[First Defense Nasal Screens are available online. One pack (a weekly supply of 7 sets) of First Defense Nasal Screens costs $9.98. A 12-pack (84 sets) sells for $99. FDNS is also available on Amazon but can be shipped only in the U.S.]
