The special feature of this mask is that it is inlaid with 18K gold and diamonds, made by an Israeli jeweler and owned by a businessman in Los Angeles, and equipped with N99 filter according to his requirements. This mask is called the most expensive and luxurious mask. The global epidemic is very serious, so it is necessary to wear a mask. However, it is the first time 1 that we have seen such an expensive mask.
This diamond mask contains 3040 diamonds and was designed by Jack Bao, a private luxury watch and jewelry manufacturer based in Manhattan. Although the mask style is the shape of a real medical mask, its function is decorative rather than protective.
Mask type
1 disposable medical mask
Daily use. The bacterial filtration efficiency (BFE) of disposable medical masks is ≥ 95%, and the ventilation resistance should not be greater than 49Pa/cm2. This mask is suitable for ordinary people to use when they are not in contact with patients with fever, cough and other symptoms. Generally, it is enough to wear when going out to take the bus.
2. Medical surgical masks
It is ok to go to the hospital. The bacterial filtration efficiency (BFE) of medical surgical masks is ≥ 95%, the pressure difference between the two sides (equivalent to ventilation resistance) is not more than 49Pa/cm2, and the particle filtration efficiency (PFE) is ≥ 30% (non-oily particles). It is also necessary to pass the synthetic blood penetration test (2mL synthetic blood 16.0kPa, internal impermeability), that is, to check whether the mask can be penetrated by spattered blood, droplets ejected by sneezing, etc.
This kind of mask is suitable for hospital environment, and has a long-distance contact of more than 3 meters for patients with fever, cough and other symptoms. It is recommended to wear it when going to the hospital or visiting patients.
3, medical protective mask
Use when contacting patients. Medical protective mask can filter most microorganisms, resist splashing of blood and body fluids to a certain extent, and its outer surface is waterproof and highly sealed. Its particle filtration efficiency is greater than or equal to 95% (non-oily particles), and it has a certain surface moisture-proof performance through a higher standard synthetic blood permeability test (2mL synthetic blood is 10.7kPa, and the inside is impermeable).
This kind of mask has a good protective effect, but it is uncomfortable, which will make users feel poor breathing. It is generally used when professionals come into contact with patients with respiratory infectious diseases.
