The present disclosure provides a filtration media for filtering one or more airborne particles. The filtration media may comprise a membrane comprising one or more polymeric layers to filter the airborne particles. The filtration media may have high filtration efficiency and high breathability. Additionally, the present disclosure provides devices (e.g., face masks) comprising the filtration media which may be used to filter airborne particles (e.g., bacteria, viruses) and to protect the wearer (e.g., from infection).

A filter is disclosed. The filter of the present disclosure includes: a support layer; and a filter layer coupled to the support layer, wherein the filter layer is formed by a melt blown method with, as a melt, a thermoplastic resin-including first base and a first antibacterial agent, wherein the first antibacterial agent includes an antibacterial metal or antibacterial metal oxide.

The invention disclosed herein relates to an odor control system including features to allow a media scrubber to function to treat a humid, or saturated, or superheated exhaust stream. In some embodiments, the system disclosed herein can capture a humid, or saturated, or superheated exhaust stream, such as from a kettle vent, and dilute the exhaust with fresh air to lower the temperature of the combined air flow below its dew point. Water is drained from the system as it condenses in the system. The combined air flow can be further diluted and/or treated according to embodiments disclosed herein such that the exhaust stream, after having excess water removed, will have a relative humidity (RH) value enabling it to be run through a media scrubber.

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 assembly for filtering toilet bowl odors including a first housing respectively disposed in spaced relation to and in fluid communication with the toilet bowl. A conduit connects interiors of the first and second housings in fluid communication with one another. A fan assembly is mounted within said first housing in fluid communicating relation with second housing, via the conduit, and is disposed and structured to define a path of fluid flow extending from an inlet of said second housing, through said conduit and a filter assembly, disposed in the first housing and/or second housing, to the exterior of said first housing, concurrent to activation of the fan assembly.

An adhesive device is capable of releasing fragrances, specifically scent patches. The adhesive device is used in the treatment of side effects associated with incontinence or an ileostomy.
