O2 Armor Nose Filters for Welders & Allergies - Nose Filter for Dust - Nasal Filters for Welding - Nose Dust Mask for Construction (10 Pack, Size Medium)

These are exactly what they say they were, but I have a hard time using them and so did my boyfriend. We couldn’t get past the weird feeling of something stuck right there in your nose. I will say for the short amount of time that I was able to wear them they did collect a lot of dust and particles. The sample set was great and really gave us an idea of the sizes that we would need to order if we could get past the weird feeling. Their design great they fit great and you can breathe through them.

So I've never seen these until I saw this on Amazon and I was curious on how it actually worked. And yes, just like the photo it just goes up your nose and basically turns your nose into an instant filter. In fact it might be better than a face mask because it actually filters particles right at the opening. As opposed to a face mask, the air around the gaps of the mask still gets sucked in unfiltered and straight into your nose. The drawback is that these are so small that if you run into any heavy particles it will just clog it up and you'll end up breathing through your mouth. I see these as more of an emergency filter, small enough to keep in your pocket, bag, or purse. I put it on in my workshop where I do woodworking and it gets the wood dust that doesn't get sucked into my vacuums. So I know it works well. But now I'm paranoid at how much wood dust I actually have been breathing in. Overall very impressed with these.

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.

Not wide enough for any kind of use. They take forever to line up proper in your mouth and you better not talk or they'll slide sideways in your nose canal. 0/10 will continue using simple foam nose plugs.

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 ❌

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!

We are loving these for spring mowing.

Didn't fit my nostrils well, but perhaps it's just me. Gave an extra star because maybe the fit is ok for others. I took a larger one to try because I wanted to know if the filtering was good when a tight seal was formed. No it didn't work in preventing my dust allergies.

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!

Works so great. I use them all the time. You wouldn’t believe how much dust they catch

Works fantastic

My first order of the large nasal filters was perfect, no defects, no oblong filters. Super happy with the protection from most* of the coal dust where I work. Just having something other than a half mask is great. My second order has been mostly misses. I have had a LOT of filters that were odd shapes that didnt really do the job. One nostril would have black boogers and the other would be a little Grey. If it was just a few that were a little messed up I wouldnt be bothered, but I would say half have been weird shapes that just slip into the nostril or just let everything by. Its as if they are too skinny even though they are large.

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
