Why not?
I flew during flu season Jan 2026 5 times and used this before and during my flights. I truly don’t know if it worked but I did not even get a cold. I was exposed to strep throat and did not pick that up either that same week. Coincidence? Maybe but I don’t care.. I’m all for using this again!!

The best defense against viral threats
This is a fantastic product! I have tried various nasal sprays and this one shines above the rest. First, it's important to consider that this is not a spray to be used after being exposed to airborne viruses. This is a preventative measure before exposure and if used for that purpose, while it is hard to prove effectiveness, I can say that I feel confident it works! I've tried other products that all have limitations,whether it be limited number of sprays or the product causing burning and nasal irritation. This product lasts a reasonable amount of time and causes no discomfort. They also have a very comprehensive set of tests they've shared that support it's effectiveness in protecting against airborne threats. In general, I strongly recommend this product to keep yourself protected in public spaces where wearing a mask is not possible or desirable. Very good product and very good price!

Cold and Flu Defense
I use as directed. Everybody I work with (and that means lots of high school students) seems to be getting sick right now. I’m using it daily right before work and so far so good. I also use it before bed if my husband has been around sick people. I plan to re-order and use at least through March.

Stuffy nose
I suppose this works but while traveling I used it and got a terrible stopped up nose. Thought I was catching a cold but when I stopped using it my nose unstopped and I didn’t have a cold at all, so I’m assuming this was the cause of the stuffy nose.
