Frequently Asked Questions

How do I assemble the idMask?

Watch our instructional video below:

How do I know which size fits my face?

The easiest way to measure your face for the right sized idMASK is to do the following:

1. Get any credit, bank or door access card. Holding it vertically, align the top edge of the card with the middle of your eye level. 

2. Note which part of your face the lower edge of your card now aligns with. 

  • If it aligns with your lower lip or above, you need a Large
  • If it aligns with your mid chin to your lower lip, you need a Medium.
  • If it aligns with the bottom of your chin or lower, then you need a Kid size. 

If in doubt, we recommend that you choose the larger size.

Does the idMASK protect against Covid19?

idMASKs use the same electrostatic filter media as N95 masks. Our filters are able to capture the same particulates as the N95, while our silicone seal ensures an airtight fit, eliminating the leakage problem with the disposable N95 mask. idMASKs have not been specifically tested against Covid-19, but these tests are currently not available.

How long do the electrostatic filters last, and how often do we have to replace it?

Our filters last 7 days for air pollution, and you’ll see it start to turn grey. For the virus, we suggest you rotate the filters daily, but rotate the used filter back in after some time to let any possible viruses die. Please also wash the other parts of the mask in soapy water after use.


How long does the mask itself last?

These masks were built to last. We still have users wearing their original idMASK from 2014.


Will the plastic break if there’s an accident?

The plastics are shatter-resistant, so they will bend but not crack or shatter from impact. We had a user send us pictures after an accident on a bike. The mask actually saved his face from pavement burns.


Can I wear glasses with the mask? Will they fog up?

Most glasses frames should fit! There are cases with some face shapes and some glasses frames that are the exception, however. Because the mask's seal is airtight, your glasses should not fog up while breathing.


Are there any facial shapes that make it hard for the silicone piece to create an airtight seal?

We’ve had thousands of users since 2014, and no complaints regarding the seal with the exception of people with beards. Thick beards make it difficult for the silicone to create a seal on your skin.


Is the strap length adjustable?

The straps are both adjustable and elastic. They can be worn 2 different ways for comfort (both straps under the ears) or maximum support (one strap above and one below the ears). Please refer to the instructional video above for strap examples.


Why don’t you make disposable N95 masks? 

Our company was founded to address the problem of leakage with disposable masks. For years, we wanted our users to have airtight and more environmentally friendly options. Now, we realize that disposables are necessary for medical use, so we are developing an airtight disposable mask soon.


What is KN90, and how is it different from N95 masks?

The KN standard was just approved by the FDA. It’s almost identical to the requirements for the NIOSH American masks rating system. We are applying for the N95 rating, but it will take some time for the testing to happen.


Where is my tracking number? Is my order coming?

We are currently using a freight forwarder, and they usually take 2-3 days to give us a tracking number. Please check back on your order after a few days and it should be available then.

How do I choose a good mask and what are the benefits of each type of masks?

The benefits and limitations of each and every type of face mask:



Cloth masks are affordable and easy to make. They can stop large particles such as dust and sand, but they do very little to filter micro particles like viruses and smog. During viral outbreaks, cloth masks can help protect people by limiting how far coughs and sneezes can travel. In other words, they protect other people from the person wearing the mask.

Benefit: cheap, easy to make, available.
Limitations: lack of filtration, leakage, requires cleaning.



 Surgical masks were mainly designed to prevent a doctor from sneezing onto a patient. They do offer splatter-proof barrier for droplets but they are not very effective in terms of filtration of micro particles such as viruses and smog. They work similarly to cloth masks in their ability to limit how far coughs and sneezes can travel to other people. Surgical masks protect other people from the person wearing the mask.

Benefit: cheap, compact.

Limitations: lack of filtration, leakage.



N95’s have become the gold standard in times of viral outbreaks. They can filter 95% of micro particulates. Unlike the masks above, N95 masks protect both the person wearing the mask from other people and other people from the mask's user. These masks are certified as N95 in the USA, KN95 in China, or FFP2 in Europe. Correct fit is key for these masks, because they can leak from improper contact with the face. Different models work better for different facial shapes and sizes. Most consumers wear these masks without properly fitting them. If worn properly, N95 masks make it a bit difficult to breathe.

Benefit: good filtration, affordable, compact.

Limitations: leakage, uncomfortable, difficult to breathe.



These masks are quite new to the market. If made properly, they are a small air purifier worn on the face. The consumer needs to do research on the type of filtration material they use. These masks can also be heavy, and require frequent charging or battery changes. Attention also needs to be paid to where the fan is in relation to the filter. Fans placed behind the filter can result in micro particles inhaled due to the fan itself. As of now, we do not recommend electronic masks.



idMASKs filter micro particles much like the N95 mask with an added feature of an airtight silicone seal. The seal stops the leakage of contaminated air from entering the mask, and forces all the air inhaled through the filter.

Benefits: good filtration, airtight seal, changeable filters.
Limitations: not as compact, more expensive, requires cleaning.

What are micro particles, and how dangerous are they?

The dangers of particulate matter.

Micro particles are tiny pieces of natural and/or man made objects floating in the air invisible to the human eye. We inhale millions of these particles every minute. They consist of viruses, bacteria, mold, pollen, cement, metal dust, smog, smoke, etc. Even when we vacuum or fluff a pillow, we are releasing particulates into the air.

According to the World Health Organization (WHO) and The International Agency for Research on Cancer (IARC), particulate matter is the deadliest component in polluted air. They are designated as a Group 1 Carcinogen. These tiny particulates are suspended in the air, and when inhaled, penetrate deep into the lungs and bloodstreams causing:

  • Permanent DNA mutations
  • Birth Defects
  • Asthma
  • Strokes
  • Heart Attacks
  • Lung Cancer
  • Premature Death


What can we do to limit exposure of particulate matter?

None of us can prevent being exposed, but there are ways of limiting the exposure for personal health.

  •  Close your window when driving on the highway
  • Use a vacuum cleaner with HEPA filters
  • Use a HEPA grade air purifier indoors, particularly in the bedroom
  • Wear a mask when outdoors or in high particle environments
  • Limit the use of candles, incense, and fireplaces
  • Never smoke indoors
