Review: ممتاز جدا للأمانة و ينقي الهواء مناسب لي بما ان عندي حساسية جيوب أنفية فادني بشكل كبير
Review: I ordered Air by #M and the First Defense product. My daughter and I both suffer from allergies and while taking medication helps, it doesn't make all of our symptoms go away. While wearing a face mask is often done in other countries, I wasn't comfortable with doing that. So I thought I'd try these more discreet products. The nasal screens by First Defense were my next trial. These were much easier to install (actually you just apply them gently to the outside of the nose. No pain! Yeah! I managed to get them off just right the first time. While some say you can't feel them at all, I could but only as much as you would expect from a thin soft bandaid on your face. After about 30 minutes, I forgot they were there. Hours later I went to my daughter's school to pick her up. Then the fun began! She's 12 and was horrified that I was outside the house with "bandaids" on my nose. Well you know how overly dramatic pre-teens can be. :) As we were going out for a after-school snack in a restaurant, I decided to take them off. I did worry that this part would be painful as after all it is attached like a bandaid is. Well I gently and slowly took one off at a time and .... no pain. Wouldn't say it felt good to take it off but it certainly didn't hurt. When we got home, I had to talk my daughter into trying them on. She is the one in the family with the worst allergies. We have pets (one dog and one cat) and she has to take allergy pills every day all year long. (PLEASE KNOW THAT I'M NOT A BAD OR UNCARING MOTHER. SHE CRIES WHENEVER I SUGGEST WE GET RID OF ONE OF THE OTHER PET.). Well I don't like her taking medication every day, so I was really hopefully that one of these two products would work. I explained that she would only be wearing them in the house. And if after a few days, she didn't notice any difference, then I'd let her "off the hook" and she wouldn't have to wear them anymore. She tried the nasal screens by First Defense and made a bit of a fuss at first. But an hour later, the doorbell rang. She sprung to her feet hoping it was her best friend who lives across the street. It was the UPS man and she just politely took the package from him. About an hour later she realized that she'd answered the door with "those things" on her nose. She was mortified! Oh the drama! As the evening wore on, she did have to take them off a few time to blow her nose. But she wasn't sneezing. She always sneezes, but not that evening. Also, she was able to put the same pair back on 3 times. The sticky part probably was getting less effective but they stayed on just fine. She even slept in them (again she'd forgotten they were there). In the morning, miraculously one was still in place! Remember she'd taken the same pair off and put them back on about 4 times (last removal was to wash her face before bed) by the time she went to bed - and she's a wiggly worm in bed. Bed time is usually the hardest for her allergies as both pets sleep with her. The normal situation is she sneezes and sneezes, blows her nose about 10 times before she finally gets to sleep. This night, no sneezing and no nose blowing! Success?!?! The next day, she just put them on after school (no fuss), again had to take them off a few times to blow her nose (probably from allergens that she inhaled during the day when she wasn't wearing the First Defense screens. Within 2 hours of getting home, no runny nose, no sneezing - even at bed time! Flash forward a few days - my (adult) experience: I wear the First Defense product while at home but do take them off when I leave the house as they are easy to see and in our culture, people just don't go out in public with things on our nose or masks. I sleep in them. There is no pain or discomfort and they really do tremendously help my allergies. Flash forward - my drama queen 12 year old daughter with serious allergy problems: She happily applies them when she gets home. Sleeps in them (they now stay on just fine as she isn't having to remove them multiple times to blow her nose anymore). And ... drum roll..... her allergies have gone from about an 8 (10 being worst and 1 being best) all the way down to a 2!!!! And she isn't taking allergy pills every day anymore! Now she should just need allergy medications during seasonal allergy times (as she understandably won't wear the nasal screens to school). So while I can't completely get her off allergy medication, she will only have to take them a few months out of the year rather than 365 days/year! Air by 3M: We also tried Air by 3M nasal screens. I was hopeful when it arrived and immediately opened tried one on. Ouch!!! It is made for people with very large nostrils. It was painful to get it and once it was in it was extremely comfortable. It actually felt like it was going to make my nose raw. I'm not a sissy but I kept dealing with the pain/discomfort thinking that it would get better. I couldn't take it for more than 5 minutes. Seriously! The piece that goes in your nose has two ridges (I guess they think they are there to hold it in place) but it was so large it certainly wasn't going anywhere. And those ridges just down-right hurt! Then when I went to take it out, they made taking it out even more painful than getting it in. It was such a terrible experience that I just threw out the box. I'm a grown female adult with a normal sized nose and nostrils. I certainly wasn't going to try his on my 12 year old daughter! I'd actually give this product zero stars if I could as not only was it useless but it was painful! Conclusion regarding First Defense nasal screens: 5 stars Conclusion regarding Air by 3M: 0 stars - too large and painful to even get to use

## Questions & Answers

**Q: What happens when you sneeze?**
A: Hi.  I can only tell you my personal experiences.  These screens prevent me from sneezing.  Just be sure to clear the mess inside the nasal passages first.  
Now, my nose sometimes can get a little runny because the membranes are cooling inside...I just remove them blow my nose and reapply the same pair...They do re-stick with no problems...
I've been using these screens for a few years since Shark Tank.  It took a few sets at first to get comfortable and understand their practicality but now you couldn't ever change my mind.
These screens prevent sneezing so long as person clears out their nasal passages first...
I don't know how, but when allergies or smoke is really bad and I know this going into work or outdoors I do step #1 (clearing out my nasal passages) and then #2 turn them sideways (fits my nose better) #3 put them on before entering whatever environment I'm about to enter and that's it.
Remember that the screens are a preventative...They won't treat your symptoms but they will prevent them from ever occurring...
If you do your part, they'll do theirs...No sneezing at all...
I'm a BIG believer in these screens... 
Skeptical at first but they proved themselves to me for the past few years...
Hope this helps and thank you for asking...

**Q: Can they be re-use after only wearing them for 10-30 minutes around relatively clean air? I just can't stand strong odor from cleaning products.**
A: The filter part will most likely be okay, but the adhesive may not stick when applied the second time. I tried to adjust one after wearing for about a half hour, and it didn't feel secure. I don't believe it will filter strong odors, just particulates in the air. Good luck. Hope this helps.

**Q: How do you know what size to order?**
A: These come in 3 sizes Small, Medium & Large. Most people know if they have Smaller or Larger nostrils than an average adult. All others should use the Medium.

**Q: How many nasal filters comes in this multi pack?**
A: It says on the pig, but so small it's hard to read. There are 7 sets per pkg.
