Large Size - 7-Sets Per Pack

Bad part: They're too expensive, go through them too fast because there are only seven in a pack, and it's ten dollars a pack. If you're using them on any regular basis, it's going to add up fast. For how small and simple they seem, you should get many more for the price. I use two pairs on the days when I clean. So they only last about three days. That's not long enough in my opinion.I still gave five stars though because the product does work wonderfully for me. I have problems with dust. Any time I go to clean the house, I can't stop sneezing and the nose runs constantly. Makes cleaning miserable. I have to wear these when I'm dusting and cleaning the house. They really work for me. I bought them because of how well they work, but I'm not happy with the price. I would like to have a lot more stored up, but they're just not affordable for regular basis wear. They do look strange, but since I only use them around the house, it's okay. First Defense, you need to put at least triple amount in the package, or lower the prices, and sell them in the stores. At least thank you for making something that works though, and that I don't have to insert into my nose! I read a lot of reviews about how difficult they are to put on. I had no issues putting them on. Just stand in front of a mirror and it's easy.

Not helpful nor does the job it supposed to. I felt irritating after putting them on and its not with the hype.

As a person with a compromised immune system, the idea of being on a plane is frightening. After not flying for years, now I have to. Before I started traveling abroad in August 2011, I did some research as to the alternatives and I came across this screens. [..]I ordered them here and have been at ease every time I fly. I am traveling USA-Ecuador via Panama, with the longest flight being 6.5 hrs (COPA flight Panama/Las Vegas). So far, I can say I have not gotten sick after flying. They do work! I used them regardless of the time of the flight. They are never a waist, even on a short 1.5 hrs flight (Las Vegas-Albuquerque).Know they take some getting used to, as you do not breathe as normal. You do have to get used to deeper slower breathing. I suggest you try a pair while at home, so you do not panic at the airport. Plus, that way you will know how to put them on the right way. I usually place them on my nose as soon as they start announcing the boarding of the plane to get used to the breathing.Safe travels!

I bought these filters mostly for work because I deal with people who smoke, but still carry that smoke on their bodies and I can smell them a mile away. I saw these filters on Shark Tank and thought ok, not bad, but it occurred to me that our nostrils are black..not tan color?? These filters are claimed to be unnoticeable from a far distance, but up close, you will look weird. I think I rather wear a face mask instead. I think these filters would have been great if the maker made the filter black color with tan edging to blend in with the nose, now that would be not noticeable too much. Make the filter look like our nose hairs or something, not neccesarily sticking out of our noses. Also maybe make these filters like a dome shape where you can stick the elevated part into your nose. But they should be black regardless. Just look in the mirror right now and see what your nostrils look like....black right?? I am not going to be wearing these filters for work. I tried them out here at home and noticed that they actually lose their filtering power after a few hours of use. When you first use them you have trouble breathing, but I mean you get use to it or at least I think you do otherwise maybe its the fact that the filter material is losing its power. After a few hours it felt like I wasn't wearing them at all then I tried sniffing some clorox and could smell it...when I first put the filters on I couldn't smell the clorox bleach. The filters look very thin too. I want the makers of these to really consider making these black with tan trim and maybe a bit more thicker too. The tape is fine..it stuck on very well. I saw some other filters for the nose that actually go inside your nose and it has a little plastic thing that wraps under your nose and it doesn't look noticeable much, but the filter they use is like mesh stainless steel or something...doesn't look like they would work for smoke. Good try First defense, but your color is way off!!! Make these in black with tan trimming and I think we have a winner. And maybe make tape tan too not just clear. Hurry up please! I am dying of second hand smoke here.

These work great by keeping floating air particles from getting in your nose.
