I did some research. This is a rebrand of the Chinese Ecogaurd masks. The box was renamed Mavina with a "Made in the USA" logo and ugly printed on the mask itself. site. Inspecting the site is a broken site serving as an empty shell! The site is down! You have no items for sale. If you click on their Facebook and Twitter links, you will be directed to another company called FriCare. This is another rebrand from a Chinese manufacturer. This is misleading and unethical. The masks were decent quality but not worth the price you pay. There is no way of knowing whether these tests were legal or not. The company is not honest or transparent about their masks, so I would take anything said here with a grain of salt. Revain should investigate their false claims that they are made in the USA as they are not.
