Introduction to the use of FFP2 disposable masks

This FFP2 disposable mask can effectively filter dust and pollutants in the air, and it is not washable and can be used within the effective time.


Introduction of FFP2 Disposable Mask

First, see if the mask has FFP2 certification. FFP masks refer to masks that meet European standards. The standards of European protective masks are divided into three levels: FFP1, FFP2, and FFP3. The difference from the American standard is that its detection flow is 95L/min. This disposable FFP2 mask has a high dust blocking efficiency. The dust blocking efficiency of a mask is based on its dust blocking efficiency against fine dust, especially for respiratory dust below 5 um. The dust blocking principle of general gauze masks is mechanical filtration, that is, when the dust collides with the gauze, some large particles of dust are blocked in the gauze through layers of barriers. However, fine dust, especially dust less than 5 um, will pass through the mesh of the gauze and enter the respiratory system. The filter material of this disposable FFP2 mask is composed of fibers charged with permanent static electricity. During the process of passing through the filter material, those respirable dust less than 5 um will be attracted by static electricity and adsorbed on the filter material. Play a role in preventing dust.


Cleaning of FFP2 masks

The outer layer of FFP2 masks often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt contaminated by the outer layer will be directly When it is close to the face, it is inhaled into the human body and becomes a source of infection. When the mask is not worn, it should be folded and placed in a clean envelope, and the side close to the nose and mouth should be folded inward. Do not stuff it into your pocket or hang it around your neck.

This is a disposable mask, so it cannot be washed. Because wetting will cause electrostatic discharge of the mask, it cannot absorb dust with a diameter of less than 5um. High-temperature steam disinfection is similar to cleaning, and water vapor can also cause electrostatic discharge, causing the mask to fail. If there is an ultraviolet lamp at home, you can consider using an ultraviolet lamp to sterilize the surface of the mask to prevent accidental contact with the surface of the mask and cause pollution. High temperature can also sterilize, but masks are usually made of flammable materials. High temperature may also cause masks to burn and cause safety hazards. It is not recommended to use ovens and other facilities for high-temperature disinfection.

Use of FFP2 masks

This mask is comfortable to wear, and the mask fits well to the face and can fit the face completely. Effectively prevent dust in the air from entering the respiratory tract from the gap. At the same time, when wearing this mask, the breathing resistance is also very small, whether it is a child or an adult with poor breathing conditions, it can be worn with confidence. This mask is lightweight and should be placed properly when worn for a period of time. Do not come into contact with bacterial dust on the mask.

So how often does this disposable mask need to be replaced? In order to prevent infection, some people may wear masks all day, but this will cause the nasal mucosa to become fragile, lose the original physiological function of the nasal cavity, reduce the resistance, and make it easier to contract the virus. Therefore, in places with low population density and smooth ventilation, it is not necessary to wear masks. The actual effect of the mask cannot actually last for a day. The effective time of this FFP2 protective mask is 2 to 4 hours. If the mask is contaminated, it must be replaced as soon as possible.

When not in use, fold the medical mask and store it in a ziplock bag. It is not recommended to take off the mask and put it directly in the pocket or bag. This will easily cause secondary pollution of the medical mask. It must be folded and placed in a clean ziplock bag, and the side that touches the nose and mouth should be folded inward for storage.
