There are provided methods for treating a gas having an undesirable odor. The methods comprise contacting the gas with an acidic aqueous oxidizing composition having a pH of about 2.0 to about 3.0 and comprising at least one cation of a metal; a sequestering agent; and H.sub.2O.sub.2 and submitting the gas and the composition to UV radiation when the gas and the composition are contacting each other, wherein the treatment permits to reduce by at least 60% intensity of the undesirable odor.

A zirconium polymer composition comprising a zirconium polymer selected from the group consisting of polymeric zirconium oxychloride, polymeric zirconium acetate, and polymeric zirconium nitrate and having metal particles thereon is beneficial to aid in the removal of biological contaminants, such as bacteria, virus, yeast, algae, and amoeba, from fluids, including air and water. In this composition, the metal is selected from the group consisting of aluminum (Al), antimony (Sb), arsenic (As), barium (Ba), silicon (Si), boron (B), copper (Cu), gold (Au), lead (Pb), mercury (Hg), nickel (Ni), silver (Ag), thorium (Th), tin (Sn), zinc (Zn), and mixtures thereof, and the metal particles are about 0.001% by weight to about 30% by weight of the composition. These zirconium polymer compositions are used in methods for removing biological contaminants from fluids.

An air scenting system for a vehicle is provided which includes an appliance and a replaceable cartridge installable therein. The replaceable cartridge contains a liquid compound to be aerosolized and has a cartridge outlet through which the aerosolized compound is discharged during operation. A pump is provided to supply air to the replaceable cartridge to generate the aerosolized compound from the liquid compound contained in the replaceable cartridge, and a controller is provided for controlling the pump to supply the air to the replaceable cartridge to generate and discharge the aerosolized compound from the appliance. The appliance is particularly adapted for dispensing scent into the interior space of a vehicle, and includes a form factor particularly well suited for positioning the appliance in a cup holder. Additionally, the appliance is designed for use in vehicles when a driver is present and readily adjustable by the driver to provide a uniform scent experience.

A sterilization cabinet, comprising a top panel, at least two side panels, and a floor panel forming a part of a chamber of the sterilization cabinet; at least one door connected to at least one of the at least two side panels of the sterilization cabinet; a vent formed in at least one of the two side panels; at least one first filter covering the vent and a filter cover configured to hold the first filter against the vent; a drain positioned in the floor panel, wherein the floor panel has a slope configured to cause condensate within the chamber to flow into the drain and wherein the drain is the only outlet for the condensate along the floor panel; and a second filter covering the drain such that condensate flowing into the drain passes through the second filter.

An automated cleaning system is disclosed having a track or rail, and a body having a cylindrical or capsule configuration. The cleaning system further includes a cleaning or disinfectant solution disposed within the body and one or more nozzles secured to one or more sides of the body for dispensing the cleaning solution. The cleaning system also includes one or more wheels or bearings secured to the body, wherein the wheels or bearings are at least partially received within the track. Further, the track can be suspended from overhead within a structure. Here, the cleaning system can be automated and programmed to operate during predefined schedules with little to no human intervention, thereby minimizing the risk associated with cleaning surfaces and open areas, among other advantages.
