Videos Are Now Being Uploaded Showing Fibers That Squirm Inside COVID Masks

Many videos are now being uploaded to social media showing black fibers that move when coming close to heat sources.

Last November, it was reported that mask companies such as 3M will start using nanotechnology within their masks:

hen the COVID-19 pandemic struck, 3M announced it would boost global production of N95 face masks to more than 1 billion per year. Mask facilities in China also ramped up, increasing their capacity by nearly 12 times.

With less fanfare, several small companies responded to the pandemic by using nanotechnology to develop what they say is a better kind of mask. Using a fiber production technique called electrospinning, these start-ups have developed nanofibers that capture aerosol droplets better while providing additional breathability. Some of them are manufacturing millions of masks per month. But in the absence of funding to scale up output, their products will likely remain niche offerings, at least during this pandemic.

The BBC in 2012 reported on how nanotechnology is a danger similar to asbestos:

Inhaling tiny fibers made by the nanotechnology industry could cause similar health problems to asbestos, say researchers.

Some are similar in shape to asbestos fibers, which have caused lung cancers such as mesothelioma.

Research on mice, published in Toxicology Sciences, suggests the longer nanofibres are more dangerous.
