Reskur – PDP Benefits
Lung Protection Pollen Defense Fits Under PPE All-Day Comfort Lab-Tested

3M Advanced Electret Media

Lab-grade filtration.
Inside your nose.
All day.

Reskur sits invisibly in your nostrils and pulls dust, fume and pollen out of the air you breathe — up to 99% capture of 1–10 micron particles, independently lab-tested, with airflow left wide open and your face completely free. On the jobsite or through allergy season.

Reskur

Why it works

Independently lab-tested

Up to 99% capture

3M Advanced Electret Media, independently lab-tested, captures up to 99% of 1–10 micron particles at typical breathing airflow.

Stops the deep stuff

Catches respirable particles under 5 micron — the size small enough to reach the gas-exchange tissue deep in your lungs.

Pollen, drug-free

Intercepts grass, birch and ragweed pollen at the nostril — before it triggers the sneezing. No pills, no drowsiness, no rebound spray.

Breathe wide open

Charged fibers attract particulate instead of blocking it. No dense, suffocating mesh — airflow stays free while filtration stays high.

Invisible under any PPE

Zero added bulk under a hood, hard hat or respirator — and unseen on the train or at the desk. Beard or stubble, the fit doesn't change.

8–12 hours, forgotten

About 30 seconds in, you stop feeling it. Four sizes (S–XL) for a real seal. No fogged glasses. No chin-strap fatigue.

Drag to compare
Reskur in the nostril — after Bare nose — before Before After

Invisible once it's in. Nobody sees it but you.

Built for allergy season too

Pollen never reaches
the trigger zone.

Your sneezing, runny nose and watery eyes start the moment pollen lands on your nasal lining. Reskur stops it one step earlier — catching grass, birch and ragweed pollen right at the entrance, before your body ever reacts. No antihistamine fog. No spray you get hooked on. Just breathe and go outside again.

Drug-free No drowsiness No daily pill Invisible to wear

Reskur – How It Works

How They Work

Inside your nose.
Replaces nothing.

1. Find your fit

4 sizes. Choose your right size.

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 Filter Media Matters

Most filters block particles by force — and that restricts airflow. Reskur uses charged electrostatic fibers that attract fine particles without compressing your breath. Cleaner air in, full airflow out.

Reskur – Who Wears Them

Who Wears Them

Smart trade 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.

Welder

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.
Construction worker

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. Wear your N95 or P100 for the cut. Wear Reskur 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.
Woodworker

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. Reskur 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.
Allergy sufferer

Pollen season shouldn't stop your day.

Every spring, the same story: itchy eyes, constant sneezing, a nose that runs all day. Most solutions either make you drowsy, or you forget to take them. Reskur works differently — it intercepts pollen before it ever reaches your nasal lining. No pills. No spray. Just breathe.

Filters grass, birch, and ragweed pollen at the point of entry — your nose. Invisible during wear. No one sees it. Nothing changes except your symptoms. Drug-free. No drowsiness. No daily pill to remember. Clinical studies on nasal filters show significant reduction in sneezing, runny nose, and watery eyes during peak pollen season.
Reskur – PPE Stack

Where Reskur 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 Reskur is for. Not a replacement. The bridge between sealed-airway gear and nothing.

Moment Reskur Nothing
Cleanup after the cut, the bead, or the sand Yes No
Talking with the crew, walking the site, breaks Yes No
Advanced electrostatic filter media, independently 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 — we are not the same thing. For high-silica, regulated, or other sealed-airway work, wear your written-program respirator. Reskur is the layer for everything else.

Reskur – Founder

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 Reskur to fill that gap. Not a respirator replacement.

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

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

– Marcus T., founder

Trustpilot reviews

Excellent 4.8 / 5

  • "Been doing drywall sanding for 6 years. Always told myself the dust wasn't that bad. Then I tried Reskur and saw the filter after one day. That changed my mind fast. Wish I'd had these years ago."

    Tom A.

  • I work in a client's home a lot — can't walk around in a full respirator. Reskur is invisible and I forget it's there. My sinuses have been so much cleaner since I started using them."

    Kevin S.

  • "Fit is perfect with the large size. Stays in all day — no shifting, no falling out. I was worried about comfort but honestly after 10 minutes you stop noticing it completely."

    Emely B.

  • "I couldn't run outside from April to June without suffering for hours after. Now I just put Reskur in before I head out and I'm fine. Finally enjoying spring again."

    Anna L.

  • "I was embarrassed to try these at first. But no one at work even noticed I was wearing them. My sneezing went from constant to basically zero on high pollen days. I tell everyone about them now."

    James R.

  • "I was skeptical at first. But after one shift I blew my nose and saw what came out. Or rather — what didn't get in. I wear these every day now. No more black boogers at end of shift."

    Frequently Asked Questions

    Will it stay in place? I’m moving all day.

    Yes.The four available sizes (S, M, L, XL) help ensure a secure fit. It stays comfortably in place during welding, grinding, climbing, lifting, and other physically demanding tasks. Most users forget they're wearing it after about 30 seconds.

    Does it really capture fine dust like silica and metal fumes?

    Reskur uses advanced electrostatic filter media with charged fibers designed to attract and capture airborne particles that can bypass your body's natural defenses. Unlike traditional mechanical filters that rely solely on physical blockage and can restrict airflow, Reskur's electrostatic technology helps trap more particles while maintaining comfortable, natural breathing.

    This means you get powerful filtration performance without the heavy, restricted feeling often associated with conventional filters—making it easier to stay protected and comfortable throughout your workday.

    Can I wear it under my welding helmet or respirator?

    Yes. Reskur sits completely inside the nostrils and adds virtually no bulk. It fits comfortably under welding helmets, half-face respirators, and full-face respirators without affecting visibility, comfort, or the respirator’s seal. This allows you to add an extra layer of filtration while maintaining the fit and performance of your existing protective equipment.

    Does it really work against pollen?

    Yes. Reskur is designed to help reduce exposure to airborne pollen by capturing particles directly at the point of entry—the nose. By helping block common allergens such as grass, tree, and weed pollen before they reach the nasal passages, Reskur can help you stay more comfortable during allergy season and outdoor activities.

    Is it visible? I want to wear it at work and outdoors.

    Reskur sits discreetly inside the nostrils and is barely noticeable from the outside. Most users report that friends, coworkers, and family members don't even realize they're wearing it, making it ideal for daily use at work, outdoors, or while commuting.

    How long does a filter last, and when should I replace it?

    Each filter is designed for a full day of use or approximately 8–12 hours of wear, depending on conditions. In environments with very high pollen levels, dust, or airborne particles, replacement may be needed sooner. For optimal performance and hygiene, a fresh filter is recommended each day.

    ★★★★★Great for being outside

    I spend a lot of time outdoors and pollen usually ruins it for me. With Reskur my nose feels calmer and breathing feels smoother. Easy to pop in and carry on.

    ★★★★★Finally something I'll actually keep using

    I've tried sprays, tablets and strips. These are different because there's no dose to remember and no side effects. Not a miracle cure, but they genuinely cut the irritation when I'm out and about.

    Pollen season used to start my day with sneezing and a blocked nose. I put them in before I leave and I'm good to go. Day-to-day life is noticeably easier, especially commuting.

    Big stress reducer. I don't like feeling drowsy from tablets, so I wanted something drug-free. These make me feel more in control when pollen is high, especially in the mornings.

    ★★★★★Good, but you need a routine

    Once you get into the routine of fitting them properly they're genuinely useful. Being outside feels easier and less irritating. Knocked a star off only because I wish the first-time fit guide was clearer.
