A filter module and an air purifier according to an aspect of the present disclosure include a supply roller and a recovery roller, a filter wound and installed on the supply roller and the recovery roller, so that it can be used without replacing and cleaning the filter module for a long period of time by allowing a section used in the filter to be recovered in the recovery roller, and also a section not used in the filter to be supplied from the supply roller.

Provided is a cartridge assembly having first and second cartridges sealed by an interface member having a first sealing member along a radially outer surface thereof having a non-planar geometry around the outer surface and a second sealing member along the radially outer surface having a non-planar geometry around the outer surface. The sealing members may each have a repeating, undulating, non-planar geometry around the outer surface. The cartridges have ends with matching geometries to allow the cartridges to engage in surface-to-surface relation around their entire extents to create with the interface member an air tight seal.

A filter cartridge for an air cleaner assembly is disclosed. The filter cartridge can include a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter. The filter cartridge can also include a circumferential shell surrounding at least a portion of the media pack outer perimeter. A radial flange extending from the circumferential shell proximate the media pack inlet end can also be provided. The flange can define a plurality of openings that are configured to receive protrusions on a housing body of the air cleaner assembly. The interaction between the protrusions and openings operates to ensure a secure seal between the housing body and the seal member.

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 apparatus for storing a mask includes a main body comprising a first region and a second region, the first region having a plurality of mask containers, a gas supply pipe having an outer portion outside of the main body, a fan in the first region to propel the gas from the second region to the first region, a filter disposed at a front end and/or a rear end of the fan, a heat exchanger in the second region and configured to exchange heat with the flowing gas, a Peltier element at the outer portion of the gas supply pipe, a first sensor installed in the gas supply pipe upstream of the Peltier element, a second sensor installed in the second region in a lower position to the heat exchanger, and a controller connected to the first and second sensors and the Peltier element.

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 housing main part of a filter housing has an element receiving space and an adapter chamber. A filter element is inserted into or removed from the element receiving space through a lateral mounting opening. A pre-separator module and the filter element are arranged behind each other along the main flow axis of the fluid to separate an outlet from an inlet of the filter housing. The adapter chamber accommodates the pre-separator module and/or the filter element. The adapter chamber is arranged at an axial end face of the housing main part and is open axially toward the element receiving space and, axially opposed thereto, toward the environment. The mounting opening is surrounded by a cover receiving rim that extends across the adapter chamber. A part of a connecting device within the housing main part is used to attach the pre-separator module to the housing main part.

A waste gas scrubbing tower includes a tower body unit, a filtration unit arranged in the tower body unit, a washing unit that introduces water from an external supply into the tower body unit. The tower body unit includes division boards that define a plurality of channels through which waste gas flows, the tower body unit including a waste gas inlet opening and a waste gas outlet opening. The filtration unit includes a plurality of filter members, which are arranged in the channels. The washing unit is operable to generate water mist curtains in the channels to wash the waste gas so that the waste gas that enters the waste gas scrubbing tower is subjected to multiple times of washing and filtration and purification.

An air filter arrangement is disclosed. The air filter arrangement includes media comprising corrugated media secured to facing media and defining a media pack having opposite flow faces. Media pack arrangements including such media are described. Also described are filter cartridges including such media packs and air cleaners including the filter cartridges. Advantageous housing seal arrangements having a pinch seal member and forming a trough are described. Methods of assembly and use are also provided. Also, systems of use are described.
