Peijiu Medical Technology Limited Company provides comprehensive anti-virus, anti-bacterial and anti-fungal solutions for the public and medical community. Our goal is to use a series of anti-viral, anti-bacterial and anti-fungal materials such as copper oxide nanometer non-woven cloth and cotton woven cloth to develop and produce wound dressings, masks, diapers, sanitary napkins, clothing, protective clothing, bedding and other products. For the present pandemic, we have successfully developed an effective anti-COVID mask--Copper-oxide double impregnated disposable mask. This mask can effectively inactivate virus in direct contact, therefore, leave the least chance for virus staying on the mask. Meanwhile, it keeps all other features such as breathability, convenience and price efficacy as normal masks.
