Abstract: An air filtering mask is disclosed which includes a rigid component and a flexible component. The rigid component and the flexible component combine to form a space over a user's mouth and nostrils, to form a seal therearound and to maintain the mask in place. The mask also includes an exhaust port with an exhaust filter and an intake port with an intake filter. The mask further includes an air mover pulling exhaust air out the exhaust port, thereby drawing intake air through the intake port.

Abstract: 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.
