  • Publication number: 20190209954
    Abstract: The present disclosure relates generally to improved room air purifiers and filtration media for use in room air purifiers. In some embodiments, the room air purifiers and media exhibit excellent filtration of cigarette smoke and/or formaldehyde. Some embodiments include a multilayer filtration media, comprising: a fluorinated electret layer; a sorbent layer adjacent to the fluorinated electret layer; and an optional backing layer having a Gurley stiffness of at least about 200 mg; where the backing layer is not present, at least one of the fluorinated electret layer, the sorbent layer, or the combination of the two layers has a Gurley stiffness of at least about 200 mg. In some embodiments, the filtration media is pleated.
