This stuff works, thought I would try ,have an auto immune disease. Haven’t been sick at all since using daily and I’m around grandkids who get sick often .Would recommend!

The best , keep me free of germs

It work good in clearing my nose. Easy to use

Hard to know if it works, but easy to use..and so far so good! Doesn’t sting or leave lasting taste or smell.

I don’t know if this works but as a frequent traveler, I like using this when I’m flying.

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!

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.

Very easy to use, not uncomfortable or anything. I don't like nasal sprays--I have pretty bad allergies and even though all my doctors told me to use nasal sprays, I just can't do it. I hate the ones for migraines too; they're just likely to make me vomit sooner. So, when I say that this is comfortable and easy to use... that means a lot for me lol. I can't really prove whether this prevented covid, but I used it religiously on a cruise and did not get sick. Of course I'm up to date on my boosters, masked in busy areas, used CPC mouthwash, etc. too.
