Joe Moore faced the sharks in Season 2, Episode 2 in the episode that aired March 25, 2011, bringing their New Port Richey, FL business with them. First Defense Nasal Screen, the health and well-being, pitched in the Health & Wellness category, one of 70 health & wellness businesses to brave the Tank across all 17 seasons.
They came in asking $500,000 in exchange for 10% equity, putting a $5M valuation on the business.
Mark Cuban, Robert Herjavec and Daymond John teamed up at $750,000 for 30% equity. That priced the company at $2.5M, a haircut from the $5M the founders walked in asking for, which is how negotiations in the Tank usually go. The structure included a royalty component.
Across Season 2, 19 of 36 pitches ended in a handshake. In the Health & Wellness category overall, roughly 59% of pitches have landed a shark across the show's history.
The full story
Everything to know about First Defense Nasal Screen
First Defense Nasal Screen is a small, self-adhesive filter that sticks over the nostrils to block a large share of airborne particles like pollen, dust, dander, and other allergens before they are inhaled. Founder Joe Moore, based in New Port Richey, Florida, built the product for allergy sufferers and people in dusty or high-exposure environments who wanted a non-inserted, hypoallergenic barrier they could wear discreetly.
Moore's Season 2 appearance became one of the show's most talked-about negotiations. The sharks recognized the size of the potential market, and the bidding escalated quickly, including a headline-grabbing offer for the whole business that Moore countered for even more before that shark stepped away. Several of the remaining sharks ultimately teamed up on a joint offer that combined a cash investment for equity with an ongoing royalty.
The episode is remembered for how far Moore pushed the room. Walking away from one of the largest single offers the show had produced at the time was a bold move, and it cemented the segment as a classic. The product's simplicity, a tiny filter over the nose, paired with a huge addressable audience made the high-stakes haggling feel justified.
Where First Defense Nasal Screen is now
The exposure pushed First Defense Nasal Screen onto a global stage, helping the brand expand distribution and build out international relationships, including overseas distributor arrangements. The dramatic on-air bidding war kept the product in conversation long after the episode aired, which is exactly the kind of attention a niche health item rarely gets.
As of 2026 the company is still operating, with Moore continuing to lead it, and the product remains available through its official channel at filteryourlife.com. The screens are sold in multiple nostril sizes, and the brand holds patents on the design. It stands as one of the show's enduring health-product success stories.
