As an aerosol scientist and public health doctor, I have been deeply concerned at the lack of availability of high quality face masks for both medical personnel and the general public. To that end, I have specially designed a superb medical grade cloth face mask It’s been tested and retested and scientifically modified and is available to anyone who needs one.
