Hong Kong has learned from the 2003 SARS coronavirus that, MASKS HELP. Even cloth masks are proven to be good protection. For example, the HK Mask, created by a Hong Kong chemist Dr. K Kwong, was lab tested on its filtration efficiency at MPPS (0.3 micron particle size) standard. Two layers of kitchen papers as filter can provide up to 91.3% filtration efficiency! Details👉🏻diymask.site
As the governments are easing their lockdown restrictions, UNIVERSAL MASKING allows us to get back to our social lives while protecting each other. We never want the second wave of Covid-19 to happen.
For those countries that are still battling hard with the virus, please consider wearing masks. It is useful protection, and a CIVIL RESPONSIBILITY. Universal masking helps contain the virus, so that we can get back to normal lives sooner.
Please spread this life-saving message to the world.
Save our lives, wear a mask.
We will conquer this virus together 🧡
