An exhaust unit includes a dirty air intake opening, a clean air output opening and an airflow path defined between the dirty air intake opening and the clean air output opening. The exhaust unit further includes an upstream quenching section and a downstream filtering section along the airflow path. The quenching section has a wetting chamber that includes a reservoir having a fill level for a quenching liquid, and a downtube connected over the dirty air intake opening and opening at its end above, and in opposition to, the plane of the fill level.

The present invention relates to an improved water pipe comprising a chamber containing water in its lower portion, its upper compact cylindrical portion serving as a smoke collection reservoir; a bowl for combusting tobacco or medicinal herbs, the smoke directed through a tube to the water chamber below the water; and a mouth piece for applying suction to the interior of the chamber to inhale the smoke.

An active wet scrubbing filtration system for decontamination of a gas stream comprises components including one or more of: a) a vortexing apparatus which induces a contaminant-bearing gas into a helical flow; b) an initial scrubbing fluid spray section configured so as to project a spray of scrubbing fluid into the contaminant-bearing gas stream; c) an absorption structure; d) a condenser; and e) first and second scrubbing fluid decontamination systems that may be engaged or disengaged independently of each other. In some embodiments, the worksite comprises a clean room or one or more a semiconductor processing tools, which may include photolithography tools or photolithography tool clusters. In some embodiments, the active wet scrubbing filtration system may be useful in cleaning and recycling air or other process gasses for use in clean rooms or semiconductor processing tools.

Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow-establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicle, with or without using flow-establishing devices.

A filtration system for use in connection with a central vacuum system in a hospital or other medical facility. In certain aspects, the filtration system comprises a removable filter for removing contaminants; a fitting adapted for connection to a central vacuum source/system which provides constant suction, which fitting is positioned between the filter and the central vacuum source; a flow control valve positioned between the filter and the fitting; wherein the relative positions of the fitting, flow valve and filter prevent contaminants from being discharged into the central vacuum system. In other aspects, the system provides variable filter life based upon variable flow.

A filter system includes a liquid filter unit, a HEPA filter unit and an air vent cover. The filter system is installed into an in-room air vent and purifies air received from a forced air system prior to its entrance into a room via the in-room air vent. In some embodiments, the filter system further includes a means for controlling a temperature of the air such that users are able to independently control air temperature in each room of a building.
