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!

Useless: all sizes lay flat against septum, will not plug airway
These look like a good idea, but are too thin in depth to stay in place , with the filter covering the airway into nostril. Instead, each filter, of all 4 sizes, simply folds flat up against the septum , blocking little incoming air. These seem like a scam to steal $ from all the allergy sufferers who try this. The company makes a few dollars from maybe thousands of 1 time sales, as no one would buy these twice. It seems clear these were never tested on Real People. Maybe these could stay in the correct part of my nose if the center, connecting plastic string were longer. i didn't try to cut the connecter and find placement for the little filters one at a time, because I didn't want to try to dig them out after. Perhaps, if each tiny filter had a small "string" that just allowed a grip for removal, leaving 2 little "tails" to grab? Bet, that length is going to be different on different people. If they had a wider, more plug-like shape, they might stay in place, but as is, they just fold up against the septum. I feel ripped off. Checking refund policy after posting, but wanted to warn others not to waste timme and money first.

They work but need half sizes
They do work, but I wish they had half sizes. Medium is just a touch too small, so they kinda slip out if I'm breathing kinda hard. The large stay in my nose and don't restrict my breathing as much, but are uncomfortable as they stretch my nostrils out. The mediums make me feel like I have a stuffed nose and I end up mouth breathing more.

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 ❌

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

Great for welders and safety breathing
Fast shipping and the quality it’s good , I order this product for my son that work as a welder and I didn’t know that this kind of product was available to used as a protective gear for him , so far he really like the product, and comfort it doesn’t bother him the durability it’s good and the appearance of the product it’s good , the value of this it’s on the pricey point but for the safety of my son it’s worth it, the are adjustable so first buy the try out bundle so you can get the correct size

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!
