What does it mean that a team from Zhejiang University has developed a mask that can kill 99% of the new coronavirus?

If this mask can really kill 99% of viruses as advertised, it means that wearing this mask, there is almost no risk of infection when going in and out of any place.

It is said that this mask developed by a team from Zhejiang University can not only isolate viruses but also kill them. The main difference compared to other mask products is that it has two more layers of copper-based zeolite gauze, which is a key part of the anti-virus effect. Not only can it kill viruses, it can also kill viruses efficiently. According to laboratory testing, it can kill 99% of viruses in one minute. Compared with traditional masks that can only physically block, the advantage of new masks is that they will not retain viruses and will not become a source of transmission. As long as it is not washed with water, the anti-virus ability will not be lost.

But don’t be happy too early, things are not that simple. At this stage, the experimental results are only obtained by contacting the virus stock solution with the mask. There are no tests on airborne transmission and aerosol transmission. At the experimental level, this mask is immature. Moreover, the research and development team does not know enough about the anti-virus mechanism of the copper-based zeolite gauze layer, and the technology is not perfect enough. It cannot be put into production and use immediately, so don't expect to use it soon.

I personally think that even if this kind of mask is on the market, it will not be of great significance. First, because my country has controlled the epidemic very well and there are almost no new cases in the country, the masks produced have no domestic use and can only be used for export and foreign aid. The second reason is that under the above circumstances, ordinary medical masks can meet daily needs: ordinary medical masks can isolate most viruses, and better N95 masks can almost completely isolate viruses. Third, because new masks will definitely be more expensive, in the above two cases, there should be very few people choosing new masks.

Although the new mask means better results in prevention and control, it is no longer applicable in our country. Our energy is to develop vaccines to achieve herd immunity. If the new mask is successfully developed, it can be put into use in other countries with severe epidemics.
