What is the classification and intended use for Vogmask?
Vogmask is designed as Filtering half masks to protect against particles.
Our product is Korean Ministry of Food and Drug Safety Certified KF-94, GB2626-2006 Personal Protective Equipment Certified KN95, and in assessment for CE Mark Personal Protective Equipment - filtering half masks for particles, against EN 149:2001 + A1:2009 for EU market. Vogmask conforms to NIOSH N99 filter efficiency as stated in 42 CFR Part 84.181.
Vogmask is NOT classified as Masks to prevent disease – Regulated under CDRH/FDA as Class II medical devices subject to premarket notification 510(k), classified as surgical mask 21 CFR 878.4040. Surgical masks are not PPE, they protect the patient and the surgical area from contamination. Surgical masks prevent droplets being expelled into the environment by the wearer and protect patients in surgery from these being transferred to the operative site.
What size should I order?
Weight based Size Recommendations:
Small 25-50 lbs / 11-22 kg
Medium 51-145 lbs / 23-64 kg
Large 146-200+ lbs / 65-90+ kg
Extra check measurements:
What should I do if the ear loops tug on my ears and bend my ears forward?
Try stretching the ear loops to maximum length two or three times, and then try the mask on again for size and comfort. If this does not work, contact us for replacement size procedure.
What if the faceblank does not extend beneath my chin?
Once you position the side up with the aluminum noseband formed over the bridge of your nose, a properly fitting mask should reach below your chin. If it does not comfortably reach below your chin, the mask is too small to get a good seal. Try first positioning the noseband lower on your nose bridge. If that does not work, please contact us for the next size larger.
What should I do if the mask fogs my glasses?
Follow fitting instructions carefully. Make sure the side up is the side with the noseband for forming over the bridge of the nose. Form the aluminum noseband carefully on the gaps between the nose bridge and the cheeks. Your exhale should exit the mask through the exhalation valve and not out the gaps between the cheeks and nose bridge.
What is the useful life of Vogmask?
The mask can be weared for 4 to 5 months depending on the average air quality and the frequency of using the mask.
The useful life depends on the environmental conditions the mask in which the mask is worn. The mask may be reused until the Use by Date marked on the packaging. The obsolescence date is three (3) years from the date of manufacture.
Vogmask is certified as a Reusable mask product. Once the middle layer particle filtering textile is clogged with microscopic particles, there is an increase in breathing resistance and the mask should be replaced.
If any part or assembly of the mask is damaged, or if a good seal is not achievable, discard the mask.
Where is the filter and can it be replaced?
The particle filtering textile and the carbon filter are sewn into the middle layers of the mask and are the same dimension as the outer faceblank. The filter is not replaceable. After the useful life of the mask, the entire mask has to be replaced.
What is the disk on the side of the mask?
The disk on the side of the mask is a one-way exhalation valve designed to add comfort to the wearer by the free exit of moisture and CO2 of the exhale. Valved respirators protect the wearer from airborne hazardous contaminants. The one way exhalation valve is a simple ABS Resin valve with a silicone stopper to allow the exit of moisture and CO2 ffrom exhale. Depending on the ambient temperature the mask is worn in, there is always some breathing resistance in a mask, and moisture buildup but our product is certified for product safety and rated highly on comfort in comparison to paper disposable masks. The valve undergoes several Quality checkpoints in the manufacturing process from samping of raw materials to three visual and leakage tests before the individual mask is approved to be packaged and exported.
It is highly unlikely that the valve stopper is not functioning properly as the exhale opens the stopper and the inhale closes it (to prevent inward leakage).
As is indicated in the User Instructions, the valve can be checked by blowing on it from the inside of the mask to make sure the air exits through the valve. If it does, this is the proper functioning of the valve. If it doesn't, the mask should be discarded and replaced.
Does the exhalation valve filter the exhalation of the wearer?
No, the exhalation valve is made of three parts: a valve base, a silicone membrane (stopper), and a valve cover. The silicone stopper opens with the pressure of exhalation, and returns to closed position to prevent inward leakage. Valved respirators do not protect others from the wearer's exhalation. For mask use where protection from the wearer's exhale and from inhaled particles, choose a mask without an exhalation valve.
What about the filter-layers?
There are two filter layers sewn into the middel layers of the mask. One is 99% efficient for particles over .3 microns, the other is a carbon bonded to textile for deodorization.
Is there latex in the spandex trim and ear loops?
There is NO latex in the spandex trim and ear loops.
Can the valve be taken off for washing?
No, the valve is permanently heat sealed to the mask. It is fine to get it wet, This will clear it of microscopic dust and particles. If the valve on your mask falls apart, do not use the mask. Contact us for a replacement.
What are the maintenance and washing instructions?
Mildly rinse outer and inner layer with water, add a small drop of liquid soap (like dishwashing liquid), rinse again and hang dry. Store in a clean dry place free of dust. Do not store in plastic bag unless fully dried.
Is it normal to feel resistance when inhaling through a mask?
Yes, there is breathing resistance in any high efficiency particle filtering face mask. For most people, once you are not thinking about it, the resistance is not an issue. The inhalation resistance on our product is well within the acceptable range specified by NIOSH:
Test Procedure(s): Standard Test Protocol (STP) Number: STP0145 Rev 03
The inhalation resistance criteria as stated in 42 CFR Part 84.180 is an initial inhalation not exceeding 35 mm water column height pressure . The test articles submitted by the sponsor conform to this NIOSH criterion for airflow resistance.
Results: Inhalation Resistance

The carbon bonded to textile filter layer is for odors. Please take note that the charcoal for this filter layer is derived from burned coconut shells (in case that will cause a problem).
Vogmask protects from some but not all particles in second hand cirgarette smoke. Vogmask's certified N99 filter filters 99% of airborne particles of MMD (Mass Mean Diameter) 0.3 microns.
No half face piece filterting respirator will protect you from all of the chemicals and gases in second hand smoke. You would need a powered respirator for that.
Here is research on MMD (Mass Mean Diameter of particles in cigarette smoke:
The size distribution parameters obtained were similar for all cigarettes tested, with an average CMD of 0.1 micron, a MMD of 0.38 micron, and a GSD of 2.0. The MMD found using the EAA is similar to that previously reported, but the CMD is distinctly smaller and the GSD larger, indicating the presence of many more ultrafine particles. These results may explain the disparity of CMD values found in existing data. Ultrafine particles are of toxicologic importance because their respiratory tract deposition is significantly higher than for particles 0.3 to 0.5 micron and because their large surface area facilitates adsorption and delivery of potentially toxic gases to the lung.
Also Vogmaskis designed to protect from non oil airborne contaminants, but does not address the gases associated with second hand smoke. That said, many of our customers can feel immediate benefit from mask use for this purpose.
Vogmask is highly efficient at protecting from many of the particles in smoke. That is why people who wear a mask around cigarette smoke feel the mask is helpful in this environment.
Respirators are PPE and are designed and used to reduce the potential exposure of the wearer to airborne hazardous contaminants.
The following is a functional description of the Vogmask and its intended use:
- Particle filtering half mask to reduce exposures to airborne particulate matter.
- Helps to protect from non-oil airborne particles such as dust, pollen, shavings, and particles found
- Intended for general public use.
- Follow fitting instructions carefully; filtering efficiency depends on proper fitting.
- Do not use Vogmask for chemicals gases, vapors, oils, aerosols, oil based particles, or extremely
- Do not use in oxygen deficient or explosive atmospheres.
- Does not eliminate the risk of illness, diseases, or infection.
- Leakage will occur if facial hair passes under the face seal.
- This product does not guarantee protection from illness or any harmful substance.
A valved or unvalved respirator of the same class (EN 149:2001 FFP1, FFP2 or FFP3)
will offer the same level of protection to the wearer.
No respirator is 100% efficient, as there will be leakage around the face seal, around
the valve (if applicable) and through filter penetration.
Both valved and unvalved respirators are designed to help reduce the wearer’s
exposure to airborne particles.
Protection from inhaled airborne contaminants
Making people aware of the urgent need for cleaning up the air we breathe
Vogmask has been dedicated to environmental activism and raising awareness of the challenges and hazards of poor air quality. Last year Vogmask participated in a campaign with World Wildlife Fund called Clear the Haze by providing custom Vogmasks featuring this message. We have worked with many environmental groups and support the educational efforts of such NGO's as Clean Air Asia and Help Delhi Breathe. We have made people aware of the hazards of pollution and provided a simple tool to protect people while the public voice demands public policy in protection of the environment.
Vogmask is for general use to protect from inhaled particles such as PM 2.5, pollen, dust, and other airborne contaminants. The carbon filter layer provides deodorization.
