An ionization device may be configured to be portable, and to rest on a surface such as a floor or desk top. The ionization device includes an air-intake port, an ion generator, an ozone catalyst for removing at least some ozone from air, and an air discharge. Air enters the device through the air-intake port, and at least some of the air is ionized to remove particulates. The air is then moved past or through the ozone catalyst to remove at least some of the ozone from the air. A controller may be used to monitor particulates, temperature, humidity, and/or other relevant factors and/or to adjust the ionization level.

The invention relates to a modular, portable, air purifier device capable of supplying filtered or otherwise conditioned airflow to an individual. More specifically, the present invention provides an air purification system that allows for the remote detection and analysis of local ambient air quality and transmit that information to wirelessly connected devices.

An apparatus and method for treating air. A housing can enclose a heating zone and an oxidizing zone positioned downstream of the heating zone with respect to a flow direction of the air being treated. A catalyst in the oxidizing zone oxidizes contaminants from the air, and an air mover positioned is configured to move air from an air inlet through the housing to an air outlet. An air treatment cycle can include an air cleaning mode at a high air flow and a self-cleaning mode at a lower air flow. A heater is operated during the self cleaning mode to oxidize contaminants that on the catalyst from the air cleaning mode.

A portable or handhold air purification system, whose air flow pipeline made of highly reflective and low absorptive material for UVC or UVB light acts also as a UV light waveguide, is invented. The system is based on the design concept of maximizing UV light exposure dosage to deactivate all the pollutants in the air flow going through to allow the system to use UVC and/or UVB LED. The system also has some features around the middle point of the air flow path to either further increase light exposure, or clean the air flow through the interaction between the specially designed nano particles and incoming UV light. Moreover, an ozone filter and an air heating devices, with energy either from the heat sink of LED's TEC or a device based on plasmonic resonance induced photothermal effects, are placed near the air outlet of the system for further enhancement. The system is very useful for travelers in the closed environment such as in a airplane, or on a train. It can also use in office during flu season as well as provide cleaned air supply to its users against the hay-fever.

An inkjet printing apparatus includes a first stage on which a substrate is disposed, an ink storage portion including ink and a plurality of pollutant adsorption balls dispersed in the ink, a head portion including a nozzle configured to eject the ink supplied from the ink storage portion to the substrate, and a gas discharging portion disposed on a side of the ink storage portion.

An apparatus for the inactivation of airborne pathogens and pathogens on the surface of an object. The apparatus including a housing with an intake region and an exhaust region and an airflow path disposed between the intake and exhaust regions. The apparatus also includes a space within the housing for placement of the object as well as an intake fan and an oxidant generator proximate the intake fan. The apparatus includes an air filter disposed in the airflow path for removing particulates and pathogens and passes the intake air through either or both of an activated carbon filter and a catalyst to convert the oxidant into oxygen.

Devices, systems and methods for using photosynthetic biomass to purify water, reduce indoor air pollution, remove greenhouse gases including CO.sub.2 from outdoor atmospheric air, and produce biofuel, food products, and fertilizer are provided herein. Also provided herein are systems and methods for enhancing growth of a photosynthetic biomass in a greenhouse.

A built-in apparatus and method for treating air including a housing with an air inlet and an air outlet. An air mover positioned near the air outlet is configured to draw the air through the air inlet. The housing encloses an air treatment zone, such as including an oxidizing zone, and an ozone removal zone positioned downstream of the air treatment zone and oxidizing zone. The air treatment zone includes UV light and/or ozone that partially oxidizes the chemical contaminants in the air treatment zone. A catalyst in the oxidizing zone oxidizes elements within the air treatment zone. The ozone removal zone includes a second, different catalyst material. A UV bulb that may or may not generate ozone is positioned within or downstream of the first and/or second catalyst materials to assist catalyst oxidation and/or self-clean the apparatus.
