The detection of FFP2 masks, whether it is a European standard or an American standard, is designated to use the American TSI-8130 Automated Filter Testers instrument. The American standard uses the NaCl method for class N, the R class uses the DOP method, and the European standard uses the DOP method.
The TSI-8130 instrument uses the NaCl method: the instrument can automatically generate salt particles, the average diameter of the particles is 0.2μm (aggregate average diameter 0.26μm, arithmetic average diameter 0.07μm) after the sample is set to pass through the sample under a certain flow, the instrument automatically prints out Flow, resistance, transmittance.
In the DOP method, DOP oil is used to generate dust. The particle diameter of DOP oil is 0.33μm in aggregate average particle diameter and 0.20μm in count average diameter. What kind of mask is ffp2? How long does FFP2 mask last? Next, let's take a look at it in detail.
This passage is going to talk about how long does FFP2 mask last:
(1) Introduction to FFP2 mask
(2) Types of FFP2 masks
(3) FFP2 mask replacement
FFP2 masks refer to masks that meet the European (CEEN149:2001) standards. The European standards for protective masks are divided into three levels: FFP1, FFP2, and FFP3. The difference from the American standard is that its detection flow rate is 95L/min and DOP oil is used to generate dust.
Percentage of aerosol filtration: not less than 94%.
Internal leakage rate: 8% maximum. This mask can provide protection in various fields such as glass industry, foundry, construction, pharmaceutical industry and agriculture. It effectively prevents powdered chemicals. This mask can also be used as a protection against respiratory viruses such as avian influenza, COVID-19 or severe acute respiratory syndrome (SARS) associated with coronavirus, as well as against bacterial pneumonic plague and tuberculosis. It is similar to the N95 mask.
1. Disposable anti-particulate mask: alias: "disposable FFP2 mask" This anti-particulate mask is suitable for short-term use in a polluted environment.
2. Half face mask: alias: "FFP2 category mask", "dust mask", "dust mask" with exhalation valve design, reducing heat accumulation, making breathing easier, suitable for long-term use in high temperature and high humidity environments. Non-toxic, Tasteless, non-allergic, non-irritating raw materials. High filtration efficiency, low resistance, adjustable nose clip, make the mask and face more airtight, dust cannot easily leak into the filter layer after electrostatic treatment, effectively filter and absorb very fine harmful industrial dust, prevent silicosis Ultrasonic welding, the elastic band of spandex yarn material more effectively protects the wearer. Applications: construction industry, agriculture and animal husbandry, food processing industry, cement factory, textile factory, cutting dust, heavy metal harmful pollutants, workplaces.
3. Full face mask: alias: dustproof full-face mask, which is used in special environments.
How to wear a mask correctly? How often do you change it?
In order to prevent infection, some people may wear medical masks all day long, but this will weaken the nasal mucosa, lose the original physiological functions of the nasal cavity, and reduce resistance. Therefore, in places with low population density and ventilation, there is no need to wear a mask.
It should be reminded that the protective effect of any type of mask is time-effective and must be replaced regularly. It is recommended to replace the mask every 2 to 4 hours. If the mask is contaminated, it should be replaced as soon as possible.
When not in use, the medical mask should be folded and stored in a zip-lock bag. It is not recommended to take the mask off and put it in your pocket or bag directly. This will easily cause secondary contamination of the medical mask. Be sure to fold it and put it in a clean zip-lock bag, and fold the side that touches the nose and mouth facing inward.
