Filters you can trust
Replaceable filters tested to the KN95 standard — 95%+ of particles down to 0.3 microns.

| Size | Face length (nose bridge to chin) | Best fit |
|---|---|---|
| M | Up to 5.1" (13 cm) | Most adults |
| L | Over 5.1" (13 cm) | Wider or longer faces |
Measure from the top of your nose bridge to the bottom of your chin. If you're between sizes, the adjustable nose wire and soft ear loops give each size a wide range. [Confirm size chart with supplier before launch.] Wrong size? We swap it free.
Certified filtration, a fit that seals, and a design you keep — not throw away.
Certified Filtration
Replaceable filters tested to the KN95 standard — 95%+ of particles down to 0.3 microns.
See the science →Sealed Comfort
Moulded nose foam, an adjustable wire and dual exhale valves — comfortable all day.
Why the seal matters →Reusable Design
Machine-washable skin and filters that last up to 28 days — one mask, whole season.
Read reviews →It's not just cloth. Each replaceable filter stacks a fine electrostatic layer over an activated-carbon core — independently tested to the KN95 standard at over 99% filtration of ultrafine particles down to PM0.1, while the carbon layer adsorbs the exhaust fumes, VOCs and odours that plain fabric lets straight through.
Filter material independently tested against the KN95 benchmark — over 99% filtration efficiency for ultrafine particles down to PM0.1 under lab conditions.
Shared for education. The BodyFont Air Mask is not a medical device and is not a substitute for medical-grade respiratory protection.
Lab testing to the KN95 standard shows over 99% capture of ultrafine particles down to PM0.1 — the fraction in smoke, smog and emissions that travels deepest into the lungs.
The activated-carbon core adsorbs volatile organic compounds, solvents and everyday smells — so city air feels, and smells, cleaner through a full day of wear.

I ride through downtown traffic twice a day. With the valves I can actually breathe hard on the climbs, and the carbon layer takes the exhaust smell right out.
Twelve-hour shifts and my disposables always dug in behind my ears. The loops on this one are actually soft, and I just swap the filter instead of tossing a mask a day.
Sanding hardwood all weekend used to leave me congested for days. Wear this in the shop now — fine dust doesn't stand a chance and it never fogs my glasses.
Pollen season used to run my life. This is the first spring in years I've gardened without paying for it after. Sealed fit makes all the difference.
Demo days are full of drywall dust and who knows what. It seals properly, breathes through the valves, and the skin washes clean every week.
I'm on planes twice a month. It's comfortable enough to wear gate to gate, and recycled cabin air doesn't bother me anymore.
Breathing resistance was my problem with every mask — hard efforts felt like sucking through a straw. The dual valves fix exactly that.
On my feet at the salon all day around sprays and product fumes. The carbon layer genuinely kills the chemical smell. Slim enough that clients don't blink.
Spray finishing without a bulky respirator: this handles the overspray smell and fine particles, and I can actually talk to customers wearing it.
Mowing and blowing leaves all day — dust, pollen, two-stroke exhaust. One filter lasts me about a month of full-time yard work.
When the smoke rolls in every August, the whole valley smells like a campfire. This is the only mask that made the air feel — and smell — clean.
Fumes at the shop all day. It seals under my helmet, the steel valves vent the heat, and it doesn't turn into a swamp by noon.
Bus then subway every morning. It's comfortable the whole commute and I stopped burning through boxes of disposables — one filter a month.
Hair clippings and product in the air all shift. Comfortable, easy to talk through, and the washable skin means it never gets gross.
I keep one in my classroom bag for flu season. Soft loops, no fog on my glasses, and I can teach a full day in it without thinking about it.
Sawdust is constant in my line of work. The seal around the nose actually holds when I'm bent over a bench all day.
My doctors want me careful in crowds. This one filters better than the disposables I was using and it's comfortable enough that I actually keep it on.
Running along the main road at rush hour felt counterproductive. Now the exhaust doesn't reach me and the valves keep the airflow easy on tempo days.
