FILTERFORCE™ Nose Filters
FILTERFORCE™ Nose Filters
Invisible nasal filters that protect you the moment your respirator comes off.
That's 60 to 80% of your shift spent breathing in dust, fumes, and particles your lungs were never built to handle. And none of it comes back out.

FILTERFORCE™ Nose Filters
"Willingly getting COPD isn't tough, it's foolish. Normalize protecting yourself and tell the haters to shove it."
Is this a NIOSH-certified respirator?
Is this a NIOSH-certified respirator?
No. NIOSH certifies respirators that fully seal the airway. FilterForce doesn't seal, that's the point.
Your respirator is on for maybe 20 to 40% of your shift. The rest of the time you're between tasks, on a break, or doing lighter work where most guys don't bother masking up. Dust doesn't leave the air when your respirator comes off. FilterForce covers that time.
The media is 3M Advanced Electret Media, independently tested under a modified ANSI/ASHRAE 52.2 standard. For high-silica or regulated environments, use them as an added layer inside your respirator.
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 ONE SHIFT inside a welder's nose. 8 hours.
That black residue is metal fumes, iron oxide, manganese dust, and fine particulate matter from grinding. Every single particle on that filter would have gone straight into his lungs without FilterForce.
This is what causes COPD.
This is what causes occupational lung cancer.
This is the reason tradesmen end up on oxygen.
Not bad luck. Not genetics. This.
Shift after shift, year after year, until the damage is done and the doctor tells you it's permanent.
Lung tissue does not heal. It does not grow back. What's gone is gone.
Now multiply that one filter by 250 shifts a year. By 20 years on the job.
That is 5,000 shifts of this going directly into your airways while you kept your head down and did the work.
Most tradesmen find out too late what they're breathing in...
No BS. All Facts. Read for yourself

Foreman on a job site with 14 guys. Bought a pack to try. Now 11 of them use them every day. How these filters look after the our shift says enough.

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.
By the way here is what it caught.

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 after seeing what these things caught

30 years in a steel mill. After seeing what these catch, I wish someone had told me about them on day one. Better late than never.

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.

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.
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

Your Questions, Our Straight answers.
Is this a respirator replacement?
Is this a respirator replacement?
No. For heavy fume work always wear your respirator. FilterForce is for the 60 to 80 percent of your shift when that respirator comes off. Between passes, during grinding, during cleanup. That's when these work.
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, zero bulk. Wear them under any hood, hard hat or respirator. They do the work during the 60 to 80 percent of your shift when your respirator is off.
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.
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.
