An improved cartridge, typically in cylindrical or panel form that can be used in a dry or wet/dry vacuum cleaner. The cartridge is cleanable using a stream of service water, or by rapping on a solid object, or by using a compressed gas stream, but can provide exceptional filtering properties even for submicron particulate in the household or industrial environment. The cartridge has a combination of nanofiber filtration layer on a substrate. The nanofiber and substrate are engineered to obtain a maximum efficiency at reasonable pressure drop and permeability. The improved cartridge constitutes at least a substrate material and at least a layer including a non-woven, fine fiber separation layer.

An artificial cigarette, inhaler or other nebulizer device may include a housing, an air passage into the housing, a fog generator chamber within the housing connected to the air passage, a liquid source connected to the fog generating chamber, and a fog generator within the fog generating chamber for receiving liquid from the liquid source and creating an aerosol. The fog generator may be an ultrasonic nebulizer and/or a pneumatic nebulizer.

The invention provides a catalyzed soot filter formed on a wall flow substrate having internal walls coated with catalyst compositions. The soot filter maintains a homogeneous flow of the exhaust gases through the internal walls of the substrate along the length of the filter due to the coating design. Both the efficiency and the durability of the catalytic function are increased over conventionally designed catalyzed soot filters. The catalyzed soot filter provides an integrated function for simultaneously treating the gaseous components of the exhaust (e.g., CO and HC) and the particulate matter deposited in the filter.

A cyclonic vacuum cleaner includes a body portion, a nozzle portion and a dirt cup which is removable from the body portion. The dirt cup collects dirt and other debris separated by a cyclone and a cyclone slinger portion in the body portion. A main filter may be housed in a transparent filter door downstream of the cyclone. The dirt cup may be inserted into and sealingly held within the body portion by using a rotational camming structure.

The present invention provides an amine functionalised adsorbent for use in dry scrubbing process. The adsorbent comprises amine functionalised mesoporous silica in which the amine groups are present at or near the surface of the silica, including within the pore walls and channels of the silica. The present invention further provides methods of preparing the adsorbent and of using the adsorbent for the adsorption of CO₂ and/or other acid gases.
