They work
I am a mechanic and work on big trucks outdoors. This has helped a lot with my outdoor allergies and allergies from dust/dirt from working breaks dust and what not. I have big nostrils and these fit perfect and get the job done.filters very well.

Welders/grinders/everyone. Must have.
As a welder these are a must need especially if you know you have to be in a confined area or space and need to filter out the small particles, usually changed them after lunch and it would last until the end of the day! The breathing is easy but definitely something to get used to the thickness of the filter was perfect too. The appearance is almost none if someone isn’t looking too hard. It’s light and somewhat durable as long as you aren’t trying dig for gold. It’s definitely worth its value for money. Overall good product

stupid purchase
this was one of the dumbest things I ever purchased. My son is a welder, I thought this would be a good filter, however, they are like tampons you stick in your nose. I am not sure how you breath through them, but he laughed his butt off at how stupid I was for purchasing these things

They could be better
I think that they’re great in concept but in execution they’re lacking. There needs to be a separate piece of plastic inside where the filter faces inward because I found that I ended up breathing in small bits of the cotton barrier, and that can’t be good for you. If they were more rigid and could be sold with just the cotton pieces that could be replaced that would be top tier. Just some food for thought.

Sinus saver!!
These are great! I do a lot of pasture mowing. This stirs up a lot of dust and weed debris. It is so great to come inside after wearing these and have clear breathing plus no cough for the next couple of days. You do have to get them in properly or it interferes with your breathing.

Comfy. Flexible. Pleasant. Nearly invisible.
I used this variety pack to determine which size I would need for my nose. I have the most average white boy nose you can think of. Not long, not short, not wide, not narrow, not big, not small. I work as an AC Ductwork installer and I plan on using these while in attics where I'm swimming in fiberglass. For this application, medium fits me the best, and large will still work properly (even if they stretch my nostrils out). Extra large is *very* difficult to fit into my nostrils and are incredibly uncomfortable. They also fold the filter significantly. Will update the review if I notice they don't do their job at blocking fiberglass (my throat gets itchy) extra small and small seem like they're exclusively for kids and I do

A Must-Have for Every Welder!
Title: A Must-Have for Every Welder! As an avid welder, I can confidently say the O2 Armor Nose Filters are an absolute game-changer. I’ve tried other solutions to reduce exposure to fumes and debris, but nothing has come close to the comfort and effectiveness of these filters. They fit snugly in your nose without being uncomfortable or intrusive, and they don’t interfere with wearing a welding mask at all. Most importantly, they do an excellent job filtering out the harmful particles and fumes that come with welding. Since I started using these, I’ve noticed a significant improvement in how I feel after long welding sessions—no more irritated sinuses or that heavy feeling in my chest. The filters are lightweight, discreet, and easy to use. You don’t even notice you’re wearing them after a few minutes. Plus, they’re durable enough to last through extended work periods. If you’re serious about welding and your health, these are a must-have. They provide an extra layer of protection that’s worth every penny. Highly recommend them to any welder out there!

Wish they would have worked better
I really wanted these to work well, but they kinda don't. Working in a fab shop in summer, it's kind of unbearable to wear a mask, so I had high hopes for these. Im pretty sure I got the correct size as I actually measured my nostrils and they fit securely, but they were very difficult to breath through. I actually found myself mouth breathing (yuck) so it just completely negates to whole point of wearing the nose filter. Great product idea that there is a real need for, but with how fine of a filter is needed to filter out the finer dust particles, definitely restricts air flow.

Medir bien su talla
Me equivoqué de talla, soy mujer y con nariz mediana. Pese a la medida me hubiera quedado mejor la talla S (pedí M) porque me ensancha la nariz . Esas son como para hombre

Save your lungs!
I used these when going to the range, it fits nicely and is hardly noticeable when wearing it. It's a game changer because I noticed how the nose filter collected a lot of the gunpowder residue and a big difference afterwards in terms of breathing. The only con about this is that it's one size fit all so naturally everyone's nose size is different, mine slides down after I let off a few rounds and I would have to nudge it back up. So in essence you will not get a 100% fit. Other that I'm definitely going to get me some more! Update: Added pictures of before and after the range. The amount of dirt/gunpowder/lead accumulated in the filter is a pretty indication that these do work! Save your lungs!
