Publication number: 20190209954Abstract: 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.Type: ApplicationFiled: August 22, 2017Publication date: July 11, 2019Inventors: Andrew R. Fox, Himanshu Jasuja, Bryan L. Gerhardt, Dennis M.

Patent number: 8097067Abstract: Herein are disclosed devices and methods that can be used to provide an indication of the need to change a filter in a small forced air handling unit, based on the actual operating time (runtime) of the unit. The methods rely on the use of at least one vibration sensor that is placed in contact with a surface of an exterior component of the air handling unit and that can determine whether the unit is operating by sensing vibrations of the surface caused by operation of the unit.Type: GrantFiled: May 6, 2009Date of Patent: January 17, 2012Assignee: 3M Innovative Properties CompanyInventors: Andrew R.
