Still blowing black
after every shift?
Invisible nasal filters that catch dust, fumes, and particles before your lungs do. Wear them under any hood or on their own.
- Seals the nose gap your mask leaves open
- Invisible to your crew. No one knows you're wearing them.
- Works under any welding hood, N95, or half-face respirator
Three steps.
Under a minute.
4 sizes. Check the Sizing Guide. Most start with Medium.
Slide them in. After about 30 seconds, you won't feel them. Weld, grind, cut, lift. They stay put.
End of shift. Pull them out. Look at what they caught. That's what would have been in your lungs.
Think of it like a HEPA filter inside your nose. Your nose has natural defenses: tiny hairs and mucus. They handle normal air fine.
But they were never built for hexavalent chromium from stainless steel, zinc oxide from galvanized, or silica from concrete cutting.
Reskur adds the filter layer your nose is missing.
This is what one shift looks like.
The filter on the right spent 8 hours inside a welder's nose. Everything on it would have gone straight to his lungs.
That black residue is metal fumes, grinding dust, and whatever else was in the air that day.
Now multiply that by 250 working days. Then by 20 years. That's 5,000 shifts worth of metal fumes, silica, and grinding dust.
All going straight to lung tissue that doesn't heal.
Why I built this.
A welder I know showed me the inside of his respirator pre-filter after one day of hard facing. It was black. Clogged.
One day. Then he told me most guys don't wear a respirator at all. Too hot. Fogs the helmet.
Doesn't seal over their beard. So they just breathe it in and blow black into a tissue at the end of every shift. Normal day.
I looked into the data. Welding fumes are classified as a Group 1 carcinogen. Same category as asbestos. Lung cancer rates are 5x higher in retired steelworkers.
Construction workers are getting diagnosed with silicosis in their 30s. And the guys doing this work every day? Most of them have never heard any of this.
The protection exists. Respirators work. But if nobody wears them because they're miserable, they're not protecting anyone.
I built Reskur to fill the gap between a full respirator and nothing. Not a respirator replacement.
An invisible filter that sits inside your nose, seals the gap your mask leaves at the bridge, and actually gets worn because you forget it's there.
Your lungs are the one tool you can't replace. – Marcus T., founderFrequently Asked Questions
Does it really work against pollen?
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.
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?
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.
Is it drug-free? I don't want to rely on antihistamines anymore.
Is it drug-free? I don't want to rely on antihistamines anymore.
Absolutely. Reskur is completely drug-free. There are no medications, sprays, or chemicals involved—just advanced filtration technology. Instead of affecting your body's response to allergens, Reskur helps reduce the amount of pollen and airborne particles entering your nose in the first place.
