An air purification device for use in an air management system includes a housing formed from a polymer matrix composite structure and a filter arranged within the housing. The filter is formed from a porous composite structure including a plurality of filter fibers such that air is configured to flow through the filter. Microbes within the air are configured to contact the plurality of filter fibers.

A method for using treated biochar to reduce the overall environmental impact of farming and minimize the carbon footprint of farms is provided. The method comprising engaging in one or more of the following practices: (1) combining treated biochar with feed or using biochar as feed for animals to reduce methane from enteric fermentation and increase animal health and nutrition; (2) combining treated biochar with compost, animal bedding or manure piles to reduce odor and increase nutrient retention; (3) applying treated biochar to lagoons to reduce odor and treat water; (4) applying treated biochar to pastures to increase pasture health; (5) applying treated biochar to crops to increase crop productivity, healthier roots and prevent fertilizer leaching; and (6) using the carbon negativity of a produced biochar to reduce the overall farm or ranch carbon footprint.

An anti-microbial metal coating may be applied to filter membranes for use in actively depressing microbial viability in filtration applications. The anti-microbial metal coating may be applied to substrates that are considered to be sensitive to damage by conventional metal coating techniques or resistant to metal bonding. The coating may be applied from a salt absorbed to the substrate in solution, converted to a reducible form with a conversion agent, and reduced to active metal format through a low temperature plasma treatment.

The invention relates to deodorizing products, and in particular, deodorizing products that find use in toileting. In some aspects, the deodorizing product is a solid substrate that disintegrates when exposed to water such as in a toilet bowl, where the solid substrate has been pre-infused with a scenting agent, for example, an essential oil or a microencapsulated essential oil. The composition can be placed directly into the toilet bowl water prior to toileting, thereby expediting the action of the scenting agent. After toileting, the scenting agent is substantially removed when the toilet is flushed. The invention can also be used as a deodorizing product without deployment in liquid water.

A jacket has a torso portion, a pair of underarm portions adjacent the torso portion, and a pair of arms, one of each of the arms being adjacent one of each of the underarm portions, the cloth defining a first area and a second area. The article further includes a first assembly including one or more scent control materials provided within the first area defined by a cloth and a second assembly including one or more scent control materials provided within the second area defined by the cloth, the second assembly having a different composition than the first assembly. The first assembly and the second assembly together include activated carbon and at least one of carbon treated to adsorb hydrogen sulfide, zeolite, ammonia stone, and carbon treated to adsorb mercaptan.
