Great product for people with allergies
Hi there, I have been using this product daily for about 8 months. I have terrible dust mite allergies and wearing this product while I sleep really helps decrease my exposure and improve how I feel. I can notice a difference in how I feel the next day. I would strongly recommend this product for anyone dealing with seasonal or year round allergies. Best part about this product is that there are no side effects. It's something that I feel comfortable using daily long-term. I wouldn't recommend wearing this product on a date or in public, but it works very well against dust, pollen and pollutants.

The perfect way prevent allergies without medicine
First Defense nasal screens are literal a filter embedded in a sticker that covers your nostrils. This keeps pollen and dust out and reduces allergies. They really work as long as you can breath through your nose and aren't sneezing too much. Definitely more comfortable than wearing a face mask. The only issue I have is that they are expensive per use.

I ordered medium. Recieved assorted but all were large. I can’t use them as the wrap around my nose and don’t stick well at all. I wish I could rate lower. I plan to return!

Pretty good
They seem to work if you stick them on right, not easy to do without a mirror. Wish it was one piece to avoid overlapping

They take a little getting use to. I have terrible allergies and like to exercise outdoors so these make it possible. It is a little bit of a problem when it is a little chilly and my nose runs. Seems be working well.

Great for woodworking, lawn mowing and more. Plus if you wear glasses no more fogging.

Worked as advertised
I thought these could be trimmed to fit the nostril, but other than that they worked great for me.
