Wear and Care

Which end is up on Airgami?

The Airgami Infinite-a logo (it looks like an infinity sign made of two letters "a" stem-to-stem) should be on your nose.

Hold Airgami by where the harness attaches. We call them the harnessing lobes. Pull onto your chin first, then your nose, then put the harness on. Look in the mirror to make sure that it's centered. The first crease below each eye and the diagonal crease on each side of the nose that goes to the bridge of the nose should go inward (valley fold), toward the face, touching the skin.

Does facial hair affect Airgami's fit?

This is true for all Filtering Facepiece Respirators (FFR). The Center for Disease Control (CDC) recommends that the skin be clean-shaven where the respirator edge seal contacts the face. Facial hair lifts a respirator's edge seal away from the skin. Even a little bit allows microscopic particles to leak in and be inhaled.

Can Airgami be reused multiple times?


Can I rinse my Airgami in clean tap water?

Yes. After you're done wearing your Airgami, rinse it thorougly in clean, potable water, preferably with a low mineral content. Allow your Airgami to air dry before reuse. This may take several hours, during which you may wish to have a second Airgami handy in case you need it.

If your Airgami is exposed to virus-carrying aerosols or dangerous bacteria, please follow one of our disinfection protocols.

Can Airgami be washed in soap, bleach, or alcohol?

No! Do not wash Airgami in soap, bleach, or alcohol. These chemicals damage the important electrostatic properties of the filter and cause it to lose efficiency.

How do I disinfect my Airgami?

Please carefully follow Airgami disinfection instructions here.

How long will my Airgami last?

Your Airgami can last a month under typical urban-wear conditions. Polluted air fills the filter faster. Breathing resistance will gradually increase to the point where it is noticeable. The filter can withstand up to 50 disinfection cycles and still exceed 95% efficiency.


Do N95 respirators slow the spread of COVID-19?

Yes. Scientists recommend upgrading from cloth masks to N95-grade respirators to slow the spread of COVID-19.

What does Airgami protect me from inhaling?

Airgami is made with an N95-grade PM0.3 filter that captures infected aerosols, air pollution, wildfire smoke, airborne dust, pollen, bacteria, and molds.

Will Airgami protect me from forest-fire smoke?

Yes, Airgami protects you from wildfire smoke as long as the smoke isn't laced with toxic chemicals, like from a chemical fire or burning toxic materials.

Will Airgami protect me from pollen and dust from yard work?

Yes, Airgami protects you from pollen and dust.

Will Airgami protect me from automobile and diesel exhaust particulates?

Yes, Airgami protects you from most particulates emanating from internal combustion engines.

Does Airgami fit children?

Yes. Airgami Small and Medium sizes will fit children aged around 9 years old and older. Please refer to our sizing chart.

Will Airgami protect me from oil-based particulates?

No. Airgami is currently made to filter only non-oil particulates.

Will Airgami protect me if there's no oxygen?

No. Airgami does not supply you with oxygen or air to breathe. Airgami filters out particulates and aerosols in the air so that you won't inhale them. Airgami should not be used in an environment with insufficient oxygen (< 19.5%) or with a high concentration of toxic substances.


What are NIOSH and FDA?

The National Institute of Occupational Safety and Health (NIOSH) and the Food and Drug Administration (FDA) are federal agencies of the United States.

occupational settings, not consumer. NIOSH relies on Nelson Labs and other independent sources to pre-certify new respirator designs by performing exactly the same breathing resistance and particle penetration tests that NIOSH will perform. NIOSH reviews manufacturing procedures, performs on-site factory inspections, and tests respirators purchased on the open market.

A responsibility of the FDA is to certify that already-NIOSH-approved respirators are complaint for use in medical settings, which includes additional testing of splash and flame resistance.

What is a surgical mask?

A surgical mask is a loose-fitting, one-time-use face covering. Surgical masks help block large droplets but do not protect the wearer from infected aerosols or PM0.3 air pollution.

What is a Filtering Facepiece Respirator (FFR)?

A FFR covers the wearer's nose and mouth and creates an air-tight seal around the edges, forcing inhaled air to pass through the filtration layers. FFRs without exhale valves filter on exhale, too.

Airgami is a high-efficiency FFR.

What are NIOSH respirator classes: N, R, and P?

N, R, and P are NIOSH respirator categories:

Rating Detail
N Not resistant to oil. Used when oil particulates are not present.
R Resistant to oil.
P Oil proof.
What are NIOSH respirator numerical classes: 95, 99, 100?

NIOSH numerical classes refer to a respirator's particulate-filtration efficiency:

Rating Detail
95 Removes = 95% of airborne particles.
99 Removes = 99% of airborne particles.
100 Removes = 99.97% of airborne particles.

For example, N95 stands for a respirator that removes a minimum of 95% of non-oil airborne particles.

Do N95 respirators trap particles smaller than 0.3 microns?

Yes. N95 filtration material can capture particles smaller than 0.3 microns in diameter. PM0.3 (0.3 micron diameter particles) are considered the most penetrating particles and are used as the standard particle size to determine a material's filtration efficiency. Filtration efficiency may be higher for different-sized particles.

What are examples of different particle sizes of air-borne pollutants and infectious agents?

Anthrax 1 — 5
Asbestos 0.7 — 90
Athmospheric Dust 0.001 — 40

What is a fit factor?

Fit factor meaures the ratio of the particle concentrations outside a respirator to the particle concentrations inside a respirator. Higher is better. A high fit factor means that a respirator seals tightly against the subject's face without leakage.

What is the Airgami filter made of?

The Airgami filter is a U.S.A-made, N95-grade, electrostatically-charged, melt-blown, polypropylene material. Nelson Labs confirmed that Airgami has > 99.5% filtration efficiency.

How is Airgami tested?

Airgami is constructed according to ISO 9001 standards. Every Airgami is individually inspected prior to shipping. Production samples are tested by Nelson Labs to NIOSH N95 standards and fit-tested in-house to OSHA N95 standards. Full test results are here.

Is Airgami NIOSH and FDA approved?

Not yet. Airgami passes all NIOSH pre-certification tests as performed by Nelson Labs — a critical step towards NIOSH approval.

Uniquely Airgami

What's so special about Airgami?

Fit, breathability, and comfort.

The unique origami design conforms to your face as you breathe, move, and talk, creating an air-tight seal around your mouth and nose without an uncomfortable nose wire.

The origami folds increase Airgami's surface area compared to conventional masks and respirators. This gives Airgami best-in-class breathability.

The adjustable harness makes a comfortable, custom fit.

Is Airgami patented?


Is Airgami a registered trademark?

Yes. Airgami is a registered trademark of Air99 LLC.

Where is Airgami manufactured?

Airgami is manufactured in the USA. All Airgami raw materials are also made in the USA.

Why doesn't Airgami have an exhale valve?

Respirators and masks with exhale valves should not be used during the COVID-19 pandemic as they allow potentially infected aerosols to escape the mask. Airgami has never had exhale valves and doesn't need them.
