FAQ

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 Certified for CE Mark Personal Protective Equipment - filtering half masks for particles, against EN 149:2001 + A1:2009 .  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.

Functional description

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 in air pollution.
  • The mask can also help reduce exposures to airborne biological particles such as mold.
  • Intended for general public use

Certain limitations apply to the use of the Vogmask product:

  • 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 high particle concentrations.
  • Do not use Vogmask 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.

 Intended use

 Vogmask is for general use to protect from particles such as PM 2.5, pollen, dust, and other airborne contaminants.  The carbon filter layer provides deodorization.  Recent research indicates that low cost carbon filters have effectiveness in protecting from ozone.

 

 

What size should I order?

Weight based Size Recommendations:

Small 25-50 lbs / 11-22 kg

Medium 51-130 lbs / 23-58 k

Large 130-200+ lbs / 59-90 kg

 Please contact us if the mask you ordered is not the proper size.

 

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 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.  

 

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. 

 

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

Test Article   Result

      1                   8.8

      2                   7.6

      3                   8.0
