A filter material composing a ceramic clay having an interconnected network of pores formed from cellulose fiber combustion is useful for removing chemical and biological contaminants from a water supply. Coating the ceramic clay with lanthanum enhances the removal of anionic species of As(V), As(III), Cr(VI), microbes and virus.

The present invention relates to personal protective equipment, specifically to a filtering device for the protection of the respiratory tract, which can be worn on the face of a user. In particular, the present invention relates to a wearable filtering mask comprising said filtering device (filtering means) for the protection of the respiratory tract and, furthermore, it relates to said filtering device (filtering means), preferably in the form of multilayer filtering means. Lastly, the present invention relates to a face mask that can be worn and configured to filter air.

The invention relates to a respiratory protection mask made of polyvinylidene fluoride and to a method for manufacturing said mask. The invention also relates to a method for reconditioning said mask. The invention also relates to a method for recycling this respiratory protection mask.

Provided are antimicrobial nonwovens comprising antimicrobial chemical treated fibers and untreated binder fibers. 0.0003-0.1 wt. % of one or more silver containing antimicrobial chemicals are used in nonwovens to provide an excellent antimicrobial/antiviral property. Exemplary applications and methods of manufacturing antimicrobial products such as a facial covering, a mattress cover, a surface cover and an air filter are provided.

The present application relates generally to filter media useful for manufacturing air filters for residential and commercial office's Heating, Ventilation, and Air Conditioning (HVAC), particularly to filters and filter media comprising soybean-based materials. The present invention provides an inexpensive, effective, environmentally friendly, and sustainable media for manufacturing HVAC air filters for residential and commercial buildings.

The invention relates to a method for producing a respiratory protection mask (1) comprising a filter material piece (2) made of an air-permeable material, comprising the steps of: providing a first non-woven material; compacting the first non-woven material in regions; bonding the first non-woven material to a second non-woven material in the compacted region.

The invention relates to a vacuum cleaner filter bag comprising a wall which is made of an air-permeable material and surrounds an inner space, and an inlet opening introduced into the wall, wherein the air-permeable material comprises at least one layer made of a non-woven and/or a layer made of a fiber web, said non-woven and/or a fiber web comprising fibers or consisting thereof, which are made from a recycled plastic or a plurality of recycled plastics, wherein the recycled plastic or the plurality of recycled plastics comprise or are chemically recycled polypropylene.

A shaped cross-section composite fiber for an intake filter is manufactured from a single material of polypropylene, without separate binder processing by using the single material of polypropylene as a filter material. The shaped cross-section composite fiber includes: a sheath comprising a reformed polypropylene resin; and a core comprising a polypropylene resin, where the sheath and the core are combined to provide a sheath-core structure.

A textile and a method of making the same comprising a microplastic collection layer, a microplastic capture layer, and a water resistant protection layer. The microplastic collection outer layer includes a plurality of openings therein for collecting microplastics from a body of water. The microplastic attraction and capture middle layer attracts and captures the microplastics collected by the microplastic collection outer layer. The water resistant protection layer protects a wearer's skin against the microplastics captured by the microplastic attraction and capture middle layer.
