My Buying Guides on First Defence Nasal Screen

When I first heard about the First Defence Nasal Screen, I was curious about how it might help me stay protected during cold and flu season. After trying it out and learning more, I want to share my experience and guide to help you decide if it’s right for you.

What Is First Defence Nasal Screen?

First Defence Nasal Screen is a nasal spray designed to help protect against airborne viruses and bacteria by forming a protective barrier inside your nose. I found it easy to use and appreciated that it’s drug-free, which made me feel comfortable using it regularly.

Why Did I Choose First Defence Nasal Screen?

I wanted something more proactive to reduce my chances of catching colds or the flu, especially during busy seasons or travel. The idea of a barrier that physically blocks viruses before they enter my body appealed to me more than relying solely on hand hygiene or supplements.

Key Features to Consider

  • Non-Medicated Formula: Since it doesn’t contain drugs or chemicals, I felt safer using it multiple times a day without worrying about side effects.
  • Ease of Use: The spray bottle is compact and simple to operate. I could easily carry it in my bag or pocket.
  • Protection Duration: The barrier lasts about 1-3 hours, so I learned to reapply it especially before entering crowded places.
  • Suitable for Adults and Children: It’s marketed for all ages, which was great since I could use it for my kids too.

How I Use First Defence Nasal Screen

I spray once or twice into each nostril whenever I’m about to be in close contact with others, like on public transport or at the office. It’s important to clear your nose before application for best results. The spray feels cool and fresh but doesn’t sting, which I really liked.

Things I Wish I Knew Before Buying

  • Not a Cure or Vaccine: It’s a preventative barrier, so it doesn’t treat or cure infections.
  • Regular Reapplication Needed: Since protection wears off, I had to remember to reapply during extended exposure.
  • Price Consideration: It’s a bit more expensive than typical nasal sprays, but I found the added peace of mind worth it.

Where to Buy and Pricing

I purchased mine online for convenience, but it’s also available in some pharmacies. Prices vary depending on the retailer, so I recommend checking multiple sources to find the best deal.

Final Thoughts

Using First Defence Nasal Screen became part of my routine during flu season, especially when I couldn’t avoid crowded spaces. While it’s not a guaranteed shield, I felt it gave me extra confidence and an added layer of protection. If you’re looking for a non-medicated way to help reduce your exposure to airborne viruses, this product might be worth trying.
