FILTERFORCE™ Nose Filters
"Willingly getting lung cancer is not tough, it is foolish. Normalize protecting yourself and telling the haters to shove it."
Is this a NIOSH-certified respirator?
Is this a NIOSH-certified respirator?
No. NIOSH covers respirators that fully seal the airway. Our filters don't seal, that's the point.
They're made with 3M Advanced Electret Media, tested under a modified ANSI/ASHRAE 52.2 standard.
For high-silica or regulated work, wear them as a layer inside your respirator, not as a replacement.
The honest answer matters more than the impressive one.
How efficient is the filter?
How efficient is the filter?
Depends on particle size and breathing rate. LMS Technologies data (modified ANSI/ASHRAE 52.2):
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 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.
YOU NEED TO SEE THIS!
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 without FilterForce©.
That black residue is metal fumes, grinding dust, and whatever else floated through the air that shift.
Multiply that by 250 shifts a year. Then by 20 years. That's 5,000 days of that going straight into your lungs.
Lung tissue doesn't grow back.
How to use?
Two steps. Under a minute.
Step 1: Insert and forget
Slide them in. Within 30 seconds you won't feel them. Weld, grind, lift. They stay put all shift.
Step 2: Check the filter
End of shift. Pull them out. See what they caught. That's what would have ended up in your lungs.
Think of it as a HEPA filter built for your nose. Your natural defenses handle everyday air just fine. But they were never designed for metal fumes, silica dust, or grinding particles.
Our filters add the protection layer your nose was never built to provide.
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. FilterForce© captures more in the worst dust.
No BS. Just reviews.

Didn't expect much honestly. But after my first shift I took the filter out of my nose and saw what these things caught. Signed up for the monthly subscription that same night.

Foreman on a job site with 14 guys. Bought a pack to try. Now 11 of them use them every day. Says enough.

Bought these for my husband after watching him cough every single morning for years. He thought it was stupid. He set up a subscription himself the next week.

30 years in a steel mill. Wish someone had told me about these on day one. Better late than never I guess.

I work construction in Phoenix. 110 degrees and these don't make it harder to breathe at all. That was my biggest concern and it was a non issue.

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 FILTERFORCE 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. FILTERFORCE 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 FILTERFORCE 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 FilterForce is for. Not a replacement. The bridge between sealed-airway gear and nothing

Why we built this
My father has been welding for over 30 years. One evening he showed me the inside of his respirator pre-filter after a single day of hard facing. It was completely black after just one shift.
Then he told me something that stuck with me. Most guys on the job don't even bother with a respirator. Too hot. Fogs up the helmet. Won't seal over a beard. So they just breathe it all in and blow black into a tissue at the end of every shift. And nobody thinks twice about it.
I started digging into the numbers. Welding fumes are classified as a Group 1 carcinogen, the same category as asbestos. Lung cancer rates are five times higher in retired steelworkers. Construction workers in their 30s are being diagnosed with silicosis. And the men doing this work every single day? Most of them have never heard any of this.
The protection exists. Respirators work. But a respirator that nobody wears isn't protecting anyone.
I built FilterForce to close that gap. Not to replace your respirator. To be the layer of protection that's always there, invisible, comfortable, and actually worn, for every minute your respirator isn't on.
My father wears them now. Every shift.
Your lungs are the one tool you can't replace.

Your Questions, Our Straight answers.
Is this a respirator replacement?
Is this a respirator replacement?
No. For heavy fume work like galvanized welding or confined spaces, always wear a proper respirator. Our filters go inside your respirator to catch what slips through the nose bridge gap. For lighter dust like grinding or sweeping, they work on their own.
Can I wear these under my welding hood or respirator?
Can I wear these under my welding hood or respirator?
Yes. They sit inside your nostrils and add zero bulk. Wear them under any welding hood, hard hat, or respirator. They catch the particles that slip through where your mask doesn't seal.
Will anyone on the job site know I'm wearing them?
Will anyone on the job site know I'm wearing them?
No. They sit inside your nostrils and are invisible from the outside. No explanation needed. No one knows.
Will they stay in during heavy physical work?
Will they stay in during heavy physical work?
Yes. Built for shop heat and long shifts. Sweat doesn't affect the fit or filtration. They stay put through 12 hours of hard physical work.
Can I breathe normally during heavy work?
Can I breathe normally during heavy work?
Yes. Zero breathing resistance. You breathe normally while welding, grinding, lifting, or climbing. The filter catches particles without restricting airflow.
What about facial hair?
What about facial hair?
Doesn't matter. They sit inside your nostrils, not against your face. Full beard, mustache, three-day stubble. No fit tests. No shaving required.
How long does one pair last?
How long does one pair last?
One pair lasts one full shift, up to 12 hours. Replace daily for best filtration. Your monthly subscription includes 30 pairs.
Is the subscription worth it?
Is the subscription worth it?
$24.95 per month. That's around $0.63 per day. Less than a cup of coffee. Invisible, comfortable, and you'll actually wear them. Free US shipping, cancel anytime.
Do they work for concrete and silica dust?
Do they work for concrete and silica dust?
Yes. For heavy silica exposure like dry cutting concrete, wear them inside your respirator as an extra layer. For general site dust, they work on their own.
