O2 Armor Nose Filters for Welders & Allergies - Nose Filter for Dust - Nasal Filters for Welding - Nose Dust Mask for Construction (Sample 4 Pack)

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.

Feels weird the first couple of days, but after a few days, it feels like it boosts the flow through my nose and definitely removes a lot of dust and metal particles from the plant I work in. I got the extra large size based off the thumb measurement size guide and they fit pretty well. It definitely seems like it boosts certain smells. I use them every day at work now instead of the mask option.

A good product, if they fit your nose. They did not fit mine very well, and I had to use a size that was larger than was comfortable in order to get a decent "seal". But, the little filters do work well and definitely made a huge difference for my allergies.

Love the idea, got these for my welding husband. He said the don’t stay in great in any size… could be user error lol

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.

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

I can't get enough air through my nose when wearing. I find myself wanting to mouth breathe, with defeats the purpose. I tried med. I think I'm between med & large. Didn't get a complete seal. It irrates my nose a bit, which makes it run.

I purchased there for my son and even tried them myself. I was shocked to see how much pollen these filtered out. My son came back inside from playing outside, only to find the filters were a bright yellow due to the abundance of pollen collected. He has severe environmental allergies. My only dislike is that there is not an option to buy them in bulk for his size.

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
