A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion above the user's head and a lower portion proximate to and spaced apart from the user's chin, an intake aperture formed in the frame, and an intake air filter covering the intake aperture. The device includes an air mover chamber attached with an air-tight seal to an inside surface of the frame and communicating on one end with the intake air filter and communicating on another end with a filtered air supply inlet inside the device and an air mover disposed within the air mover chamber and configured to draw air through the intake air filter and push air out the filtered air supply inlet. The device also includes an exhaust aperture formed in the frame and an exhaust air filter covering the exhaust aperture. The device further includes a transparent face shield attached with an air-tight seal to a front surface of the frame, the shield providing a space for air between an inside surface of the face shield and the user's face, and a fabric component comprising a first portion that is air permeable configured to cover the frame and filters and a second portion that is air impermeable extending from a back surface of the frame to cover a remaining portion of the user's head and encircle the user's neck.

Methods and systems for conducting batch multi-effect distillation are disclosed. A multi-effect distillation system and one or more isolation devices are provided. A feed stream, consisting of water and a solute, is passed from a feed source into a brine side of the plurality of heat exchangers. The feed source is isolated from the plurality of heat exchangers by closing the one or more isolation devices. A first of the plurality of heat exchangers is heated by the heat source. A steam stream and a brine concentrate stream are produced in all but a last of the plurality of heat exchangers. A condensate stream from the steam stream is produced in all but the first of the plurality of heat exchangers. A warmed feed stream is produced in the last of the plurality of heat exchangers.
