Pretty good!
I’m terrible at wearing a mask while spray painting or sanding. These do help!? Can still smell the spray paint a little bit.

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

Effective while they last
I am a welder in a mining truck fabrication and production facility. I bought these to prevent or at least reduce the amount of metal dust I was breathing in. Prior to using these I would spent 20-30 min each night when I got home blowing, picking, and flushing crazy amounts of black gunk from my nose. When I finally decided there had to be a product out there to deal with this problem I was super excited when I found these. Now before I go further I want to be clear that the filter did work as far as filtering the metal dust, but it didn’t really matter how well it worked when they also absorbed all the “liquid” in my nose with in a short amount of time. I was having to change to a new pair ever 20-30 min when working in the cold weather and when working in warm weather the would absorb any and all natural moisture in my nose drying out the inside of my nose. Even then I thought “these problems are still better than breathing in all this metal dust” , but it quickly became to expensive going through so many per shift and i decided to search out a better option. For a person using them to go for a walk durning pollen season or maybe with a less demanding job in a not so harsh environment they may work out better but for me and the 4 co workers that tried them out it was not what we hoped or needed. Also I don’t know where they come up with the nostril sizes but neither myself or any of the other 4 guys had luck with a good fit. We all had different nose and nostril shape but all experienced the either a little to big or a little to small.

Effective but Limited Fit Options
Armour Filters are Great for persons with Allergies, Welders, Doctors and others. Easy to use. Just takes a bit of getting used to **Pros:** ✅ **Strong Protection**: Blocks welding fumes, dust, and pollen effectively. Noticeably easier breathing. ✅ **Comfortable Seal**: Silicone sits securely without irritation during 4-hour welding sessions. ✅ **Reusable & Washable**: Holds up well after rinsing (used 10+ times, no degradation). **Cons:** ⚠️ **One-Size-Fits-Most? Not Quite**: - Only **one slotted shape** included. My round nostrils didn’t get a full seal until I pressed them deeper. - Armour lacks customisation. **Round nostrils may struggle.** ⚠️ **No Multi-Size Kits**: - Armour forces you to gamble on a single shape. **Verdict:** *"Armour delivers solid protection for welders and allergy sufferers, but its ‘universal’ design is a weak spot. If your nostrils match the slotted shape, they’re affordable and durable. **Tips**: - Test while moving/jaw-talking—if they dislodge, return them. - Ideal if: You’ve never tried similar oval filters successfully. - **Armour**: 1 shape, reusable ✅, no size options ❌

These work actually really good
These little sinus nasal filters actually work pretty good, except if your in a real dusty environment like I am, then you’ll be changing these a couple or more times a day, but they do work really good for nose breathing in the shop instead of mouth breathing in the shop…. I might try different sizes, because I just guessed at the size of my nostrils and they do fit pretty good, and when they are getting clogged you’ll definitely know because you’ll literally breathe them out of your nose because they are clogged up enough that just normal breathing pushes them out of your nose.. The thing is there is t a clear instruction on how to use them properly, so figuring out which side is which is a little difficult to figure out, but again they do clog up pretty fast so they aren’t suitable for a really dirty environment because the surface area of the nasal filters are so small, they can’t take too much dirt in the air before you hey clog up.. but for moderate environment they will work great and saves having to use a half face or full face respirator

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!

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!

The best dust prevention for all type of work.
Works so great. I use them all the time. You wouldn’t believe how much dust they catch

Can't breathe through your nose
If I could give it 0 stars I would, product make breathing from your nose very difficult, forcing you to become a mouth breather. Filter clogs in about 10 minutes and for the price of them, replacing every hour is unfathomable. Also not at all comfortable to wear
