A face mask developed especially for people with MCS. It utilizes the EnviroKlenz patented earth mineral technology which has the ability to chemically dismantle a wide range of undesirable chemical compounds.The fibers of the mask can filter out many common particulates. Reduces exposures to fragrances, VOCs, pollen, dust, dander, odors, and more. It’s light weight, comfortable, reusable, and latex free. I have one here and the mask itself is odor-free.
