A recirculating fan and a ventilation fan are coupled within the filter housing.

One aspect of the present invention relates to a carbonaceous material which has a benzene adsorption of 25 to 40% and a vitamin B12 adsorption of 13.0 to 50.0 mg/g, while having a pore volume of mesopores of 0.070 to 0.150 cm.sup.3/g as calculated from a nitrogen adsorption isotherm by means of a BJH method.

Apparatuses of electrochemical antimicrobial face masks and methods for manufacturing the same are provided. In one embodiment, an electrochemical antimicrobial face mask may include an electrochemical antimicrobial section configured to inactivate microbes that are in contact with the electrochemical antimicrobial section, and a filtration section configured to provide additional protection that prevents a user from breathing in the microbes, and where the electrochemical antimicrobial section is attached to the filtration section. The electrochemical antimicrobial section may include a galvanic corrosion cell membrane configured to generate antimicrobial agents via a galvanic electrochemical reaction, a hydrophilic antimicrobial membrane configured to inactivate microbes using the antimicrobial agents, and a regeneration pad configured to supply materials to the galvanic corrosion cell membrane for generating the antimicrobial agents.

The present disclosure provides a flow-through aerosol capture device that includes a chamber defining an airflow path, and at least one heat-stable aerogel filter, for example a heat-stable polymer aerogel filter, disposed in the airflow path for capturing aerosol particles when an aerosol-containing gas passes through the filter. The flow-through aerosol capture device may be a needle-trap device or a thermal desorption liner with a heat-stable aerogel filter in the lumen of the needle or the liner. The disclosure also provides heat-stable polymer aerogels and methods of making such aerogels.

An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter includes a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium includes a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame includes a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

A smell-proof portable container is provided comprising a portable case and a compartment within the case. The compartment contains a lining comprising an inner layer comprising a non-woven fabric, a middle layer comprising active carbon filtering material, and an outer layer comprising the non-woven fabric. The middle layer adsorbs odor particles and pollutant particles emitted by contents of the compartment. The active carbon filtering material comprises carbon filter fiber with activated carbon. The lining is directed to preventing smells and odors associated with the contents from being externally detectable.

A headrest assembly for supporting a head or face of a user of a treatment device includes a headrest and a filter assembly. The headrest is configured to support the head or face of the user. The filter assembly is coupled to the headrest. The filter assembly includes a filter connector that is selectively coupled to the headrest, and a filter body that extends in a generally downward direction away from the filter connector. The filter body can extend in a generally downward direction away from an inner edge or an outer edge of the filter connector. The filter body includes sides and a base that cooperate to define at least a portion of a filtering cavity that is configured to be positioned substantially directly below the head or face of the user when the head or face of the user is supported by the headrest.

A filtration media with improved filtration, strength, tear resistance and air permeability in the form of a relatively thin and lightweight wet-laid fibrous web that has a wet Mullen ratio of 60% to 80% to ensure that the media is flexible enough to be formed into a fluted structure, and strong enough to retain the fluted structure when wound into a roll and to permit further processing without the media becoming too brittle. The filtration media comprises a blend of cellulose and synthetic fibers having a weight percent of 81 wt % to 87 wt % of a weight of the media and a resin binder having a weight of 13 wt % to 19 wt % (preferably about 16 wt %) of the weight of the media.

The present invention relates to a fabric for purification of water. An object of the present invention is to provide a fabric for purification of liquids which achieves at least 2 log reductions of bacteria, and viruses. It is a further object of the present invention to provide a fabric for purification of liquids which provides high flow rates in gravity fed water purification systems. The present inventors have surprisingly found that a fabric having a matrix of polymer impregnated with organosilane superimposed on a surface of the fibre of a fibrous support not only provides reduction of viruses from a liquid to be purified at low pressure drops but also removes bacteria without using a separate microfiltration membrane and also retains high flow rates.

Disclosed is a storage-type modular data center. The storage-type modular data center includes a box, a dust removing module, an evaporative cooling module, and an air supply module. The box is provided with an air inlet and an air outlet. A server is disposed between the air inlet and the air outlet. The dust removing module is disposed between the server and the air inlet. The evaporative cooling module is disposed between the server and the air inlet, and includes an evaporative media and a water sprinkling tray module. One end of the evaporative media is immersed in liquid contained in the water sprinkling tray module. The air supply module is operative to drive air to flow between the air inlet and the air outlet.
