    No. NIOSH covers respirators that fully seal the airway. BreatheX does not seal: that is the point. 3M Advanced Electret Media. LMS-tested under modified ANSI/ASHRAE 52.2. For high-silica or other regulated work, layer with your written-program respirator. The honest answer matters more than the technically-impressive answer.

    Nose-only does not cover mouth breathing. When you are arc-welding stainless, breathing heavy through the mouth, or shouting across the shop, the air going past your lips bypasses BreatheX. For those moments, layer with a respirator. BreatheX covers the rest: cleanup, talking, walking, breaks, lighter tasks. That is 60 to 80 percent of the day for most workers.

    Depends on particle size and breathing rate. LMS Technologies (modified ANSI/ASHRAE 52.2) data:

    • 1 micron particles: 40 to 50% capture
    • 5 micron particles: 70 to 85% capture
    • 10 micron particles: 75 to 87% capture
    • Gentler breathing: higher capture

    3M's published data for the underlying media platform: 92 to 99% capture for 1 to 10 micron at typical low-flow airflow. The respirable range (under 5 micron) is the size that reaches the gas-exchange region of the lungs.

    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

    I mean they definitely work. Pic is after less than 3 hours grinding/welding in the shop. They make it a little harder to breathe obviously, it feels like having a stuffy nose. Been using them for a few days now and i just feel like my lungs are a little cleaner. To fit, measure your thumbNAIL, not your whole thumb. I got the size medium and they do fit pretty exactly. Sometimes they collapse to one side while you're wearing it but it's easy enough to pop it out and fix it, or i mean it's still better than not using it at all. I have a nose piercing and the filter definitely fits better right at the entrance to your nostril but it does also work a little further up and seals above the piercing. I might go for a size down next time just because i feel like it stretches my nose out a little. Im enjoying not having a weird nauseous headache from all the metal dust at the end of the day

    I bought these because I've had several sinus infections in the past 5 months due to my job. They seem to do a great job of keeping dust and debris from entering your nose. I do wish that they were more nasal shaped instead of just oval. It would make them easier to breathe out of and more comfortable. The price is a bit outrageous; but they have become a necessity for me so I supposed I'll have to deal.

    After putting it on I totally forgot about the filter, slept with it as well to test the filter against whatever is in the air while sleeping... within 48 hours of wearing it I was surprised by the end results Planning to buy a full year worth of box of filters for a healthier lifestyle and environment

    I cannot believe that this is the stuff that I was breathing in daily. I would have taken at least 30 years of my lifetime. 🤣 I'm currently going through 3 filters per day. Please sponsor me!

    How they work

    INSIDE YOUR NOSE. REPLACES NOTHING.

    1. Find your fit

    4 sizes. Check our Sizing Quiz. Most start with Medium.

    2. Insert and forget

    About 30 seconds in, you stop feeling them. Weld, grind, cut, lift, climb. They hold position.

    3. Check the filter

    End of shift: the white filter membrane will look darker than it went in. That is the proof of what you did not breathe.

    Why electrostatic media matters. Mechanical filters block particles physically, which costs airflow. The 3M Advanced Electret Media uses charged fibers that attract particulate down to sub-micron sizes without compressing airflow. Bonus: in humid environments, a 2.5-micron dry particle takes on water and behaves like a 4.5-micron wet droplet. BreatheX captures more in the worst dust.

    Who wears them

    SMART TRADES WORKERS WEAR PROTECTION.

    Welders between welds. Framers during cleanup. Stone masons after the cut. HVAC techs in the attic and the crawl. Concrete cutters on the walk to the truck.

     

    Between welds. During grinding. When the hood comes off.

    You wear your respirator under the hood for the long bead. The rest of the day is tacking, lighting up, grinding the prep, walking the shop, talking to the apprentice, eating lunch in the same air that just held a half-shift of fume. That is the window. That is why you blow black at end of shift.


    ✓ Catches metal fume, grinding dust, hexavalent chromium, zinc oxide.

    ✓ Fits inside any hood, half-face, or full-face respirator. Zero added bulk.

    ✓ MIG, TIG, stick, flux-core, grinding, cutting, gouging.

    Silicosis has no cure. It has prevention.

    Concrete cutting. Core drilling. Demo. Drywall sanding. Mortar. Silica is so fine you cannot see it, and it scars lung tissue every shift. Young stone masons in their 30s are being diagnosed. A recent jury verdict awarded a stone mason 52 million dollars for occupational silica exposure.

    Wear your N95 or P100 for the cut. Wear BreatheX for the rest: the cleanup, the walk to the truck, the end-of-day sweep, the conversation with the foreman.

    ✓ Catches concrete dust, drywall gypsum, respirable silica, lead, mortar.

    ✓ No nose-bridge gap. No chin strap by lunch. No soggy mask.

    ✓ Wear standalone on light-dust days, or layer inside your respirator.

    You mask up for the big cuts. What about the other 50?

    The quick rip. The fast sand before stain. The miter dust you walk through 20 times a day. The MDF you can taste in the back of your throat. The router work in a client's living room with a tarp. You are not putting a respirator on for any of that. BreatheX sits in your nostrils all shift and catches it without you thinking about it.

    ✓ Catches fine sawdust, MDF, oak and hardwood particulate, lacquer overspray.

    ✓ No fogged safety glasses at the table saw.

    ✓ Quiet protection during client-facing work in occupied homes.

    Where BreatheX fits when your respirator is off.

    Your respirator does its job for the cut, the bead, the spray. The rest of the shift (60 to 80% of the day for most workers) is what BreatheX is for. Not a replacement. The bridge between sealed-airway gear and nothing.

    Moment BreatheX Nothing
    Cleanup after the cut, the bead, or the sand Yes No
    Talking with the crew, walking the site, breaks Yes No
    3M Advanced Electret Media, independently lab-tested Yes No
    Catches respirable particles (under 5 micron, the size that reaches gas-exchange tissue) Yes No
    Fits under your welding hood, hard hat, or half-face respirator Yes No
    Wearable for 8 to 12 hours without fogging or chin-strap fatigue Yes No

    Not compared to your N95 or P100 because we are not the same thing. For high-silica, regulated, or other sealed-airway work, wear your written-program respirator. BreatheX is the layer for everything else.

    Why we built this

    FROM A BLACK PRE-FILTER TO A PAIR IN EVERY SHOP DRAWER.

    "A welder showed me his respirator pre-filter after one day of hard facing. It was black. Then he told me most guys do not even wear one. Too hot. Fogs the helmet.

    Will not seal over their beard. I built BreatheX to fill that gap. Not a respirator replacement.

    A 3M-grade filter that sits inside your nose, catches what slips through, and actually gets worn."

    "Your lungs are the one tool you can't replace."

    - Chris, founder

    EVERYTHING ELSE WORTH ASKING.

    Yes. Zero added bulk. Wear under your welding hood, hard hat, half-face, or full-face respirator. The 3M filter layer catches what slips past a nose-bridge seal.

    No. The 3M Advanced Electret Media captures electrostatically. Charged fibers hold particulate without needing dense material. Airflow stays free while filtration stays high.

    No. They sit just inside your nostrils, not against the skin. Full beard, mustache, three-day stubble: none of it changes the fit.

    One shift, up to 12 hours in normal jobsite conditions. About 4 hours in heavy dust. The white filter membrane will look visibly darker at end of shift. Replace daily for best filtration. Your monthly subscription includes 30 pairs.

    Coverage varies by plan. Most HSA/FSA plans cover air filtration items used for occupational respiratory health. Check with your benefits administrator. We can provide a receipt with the relevant product description for your claim.

    We send the right size free. No returns needed. Keep the originals or give them to a coworker.
