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.

I was highly skeptical about this product but I thought I'd give it a chance. My allergies are so bad that I'll try just about anything. I should have trusted my instincts. First Defense is supposed to help alleviate the itchy nose one gets from pollen. Ironically, these bandaid-like patches actually make your nose itch. In other words, the cure is as bad as the illness. I attached these goofy little suckers to my nostrils and hoped for the best. For the first hour the only effect I noticed was a bit more difficulty in inhaling through my nose. Into the second hour my nose started to itch, not from allergens but the nasal screens themselves. Imagine having a sticky piece of plastic attached to your nose. After awhile the plastic expands or contracts and your nose flesh is pulled this way and that. It's not dramatic, but enough to be really irritating. It started to drive me nuts so I removed the nasal screens and felt immediate relief. So if you want a distraction from your allergies, buy these. They'll take your mind off the pollen and focus it on the itchy plastic stuff on your nose.

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!

These adhesive nasal filters eliminate my allergy sysmtoms while I'm wearing them. The filter is an oval shaped, paper thin, gauze-like screen with a band-aid type adhesive ring around the outside. The adhesive ring is applied to the outside of each nostril and forms an airtight seal that stays in place while active.They are kind of tricky to get on just right and you want to try to get them on correctly with your first try. Otherwise, if you need to re-position them, they loose some of the stickiness and don't stay on as well. I tried to reuse them once and they just loose too much adhesion to use effectively a second time.In my opinion, they are way too expensive for what they appear to be, basically a small, breathable, circular band-aid. However, they work extremely well for their intended use, so I compromised. I only use these filters when I will be outside for a long period of time or in very high pollen/dusty areas. All other times I use the WoodyKnows Ultra Breathable removable nasal filter that fits just inside your nostrils.Here is my comparison of the two types of nasal filters:- These adhesive screens take a mirror to get on, every time. The removable filters are easy (with a few days practice/experimentation) to pop in and out and come with a small, plastic container.- I use the removable filters whenever I'm going outside for a smaller amount of time (ride a bike, water the garden, play with the kids) because they only take me 10 seconds to put in and position. These adhesive screens take several minutes and a mirror to do right. However, if I am going to be outside for over an hour, cutting/trimming the grass or in a high pollen/allergen area, I'll use the adhesive screens because they filter 100% and stay in place, as long as they are on. The removable filters, in my experience, filter about 70%, on average, since they move around and need to be adjusted back into place sometimes, so unfiltered air gets through in small amounts.- These adhesive filters stay in place and are always sealed to the outside of your nose, so there are never any gaps or question about whether they are letting in any unfiltered air. It is hard to tell if you have the removable filters in place correctly to filter all of the air coming into your nose. There are times when it feels right and I look in the mirror an there is a gap on one of the sides.- I also use the removable filters when I'm going out in public, since they are not as noticeable as these adhesive filters, which are very obvious and look really weird.- The price of the removable filters, compared to these adhesive filters, is MUCH cheaper per use. So I try to use these adhesive filters sparingly, when I need the "heavy duty" protection and the removables in most other situations.- These adhesive filters are only a single use, though I tried to reuse them once. The adhesive looses it's grip after being worn once and does not seal well the second time. I figure you get about a month's use with the removable filters (by taking care of them and washing them per the instructions).- Both filters feel strange to have on, even after getting used to them. They are not uncomfortable, but you know that they are there.- The removable filters that I use let more air through, so breathing is completely normal. These adhesive screens let in less air, which is probably a combination of finer screen and an airtight seal. However with both types of filters, I never felt the need to breath through my mouth due to lack of airflow through the filters, even while running or biking.I am very pleased with the filters themselves. The sizing instructions worked for me and they fit nicely. They are not the complete solution to my allergies but are one of the pieces that keep me feeling good from April to October. I've also used them while woodworking and they are much nicer to use than a mask for dust. I will probably keep buying them, even though I feel the pricing is high. Hopefully some good alternative will appear and help drive the price down to something more in line with what you are actually getting, specialized band-aids.
