Profi™ Nasal Immune Spray – Cleansing Gel Layer for Airborne Exposure, Up to 8 Hours, Drug-Free Nasal Spray for Everyday Use, Travel, Work & Crowded Spaces (90 Sprays)

Work with kindergarten and first graders every day Monday through Friday (heavy germ carriers)- Use every morning on my way to work - and when going to be in large crowds during flu season. I also use it before getting on an airplane. Seems to have worked well for me, keeping me from getting sick. Will continue to use it.

I like this spray. While it's hard to prove that it prevents colds, it seemed to help me avoid them this year and shorten the one I had. I will order it again and use it regularly. It produces no unpleasant smell or taste, so it's easy and quick to use. I have a lung ailment that requires me to be careful of respiratory illness. The product gives me confidence about going out and interacting with people.

I'm going to say this works. After getting sick twice within a month or two at the beginning of the school year and having to miss a trip because of it, I was ready to declare war on respiratory illnesses. I started using this spray whenever I was going to be close to a lot of people for more than a few minutes (like at church). I also started taking zinc, vitamin D, and sometimes Elderberry or garlic 1-2 times per day at the tiniest sign I might be coming down with something. It's now April, and I haven't gotten sick again. I think the spray has allowed fewer viruses to get in, and the supplements have taken care of what escapes the spray and tries to start an infection. I keep the bottle in my purse so I'm less likely to forget to use it. The greasy/slippery feel of it is not overwhelming and is actually kind of nice during the dry winter months. You're not supposed to breathe it in (it's only supposed to coat the insides of your nostrils), but when I do happen to have some go down my throat, it does not taste good. That said, the taste is not nearly as bad as my decongestant nasal spray. Also, of note, the bottle says to spray every 4 hours, but the description says it lasts up to 8 hours. I don't know how those statements can be reconciled. I just used the spray based on a 4-hour duration.

Bought this on a recommendation from a friend before a trip to Italy. Didn't miss a single day of the trip nor the return home due to illness or feeling under the weather. I now use it when going to any high-density event. Easy to spray and doesn't have a weird taste or throat drip. Worked for me!

The product is great and I believe it works. I’ve used it in large crowds, around others who have been sick and I thankfully have not gotten sick. I’ve just bought my 2nd bottle of this because I think it’s great, but unfortunately Amazon shipped this to me in one of those plastic envelopes and it got squished and half of the bottle spilled. This item isn’t able to get replaced through Amazon or refunded so be mindful of that. It arrived already with the plastic sticker cut open.

I used this on a cruise I took in March 2026!. Let me tell you, this is a game changer! I used it on the plane (before take-off), and then twice a day while I was on the cruise, and while the rest of the people in my group all got sick, I am happy to say, I did not. There is no smell to the product, and while it coats your nose from airborne virus, the inside of my nose didnt feel like it was coated in any film. I will not vacation again without using it.!

I was flying to Paris, and I was afraid of getting sick on the LOOOOONG flight there, which it takes me 2 flights to get there in total. I did wear a mask on the plane, but I also used this spray each day of my trip - flying, taking the metro where we were packed in like sardines, at the Louvre, which was packed, and all the places I visited in a busy city. And I did not get sick! Even on the way home on a 10 and a half hour flight where the woman next to me was coughing up a lung for the majority of the flight as well as blowing her nose and trying to touch anything the flight attendant gave to me (this woman did not sanitize or mask or anything either), and I didn't get sick. I attribute it to this stuff - expensive, but I am a believer!

I’ve used it for two trips now - a cruise with multiple flights to get there and a trip to England. Stayed healthy during and after both trips when normal for me is to get a respiratory infection after a flight, so I’m comfortable saying that this spray is great!
