An ionization chamber is provided with a series of parallel plates spaced from each other and with holes passing therethrough. Alternating plates have either a highest high voltage or a lower high voltage provided thereto, such as through a DC transformer coupled to an electric power source. Holes in alternating plates are preferably offset so that airflow through the plates occurs along curving pathways. The plates are sufficiently highly charged to cause carbon dioxide to be ionized and for carbon ions to become trapped within wells defining lowest regions of electric charge within an electric field inside the ionization chamber. Fans control airflow through the ionization chamber. A dehumidifier is provided upstream of the ionization chamber to reduce moisture content within the incoming gas. After the carbon has collected within the wells, harvesting of the carbon ions as carbon nano particle powder can occur within a carbon cache.

An electrostatic charging air cleaning device having first and second pre-chargers. The first pre-charger is configured to generate a first corona discharge to electrostatically charge PM in the incoming air stream with a first charge to form a first exiting air stream exiting the first pre-charger. The second pre-charger is configured to generate a second corona discharge to electrostatically charge PM in the incoming air stream with a second charge to form a second exiting air stream exiting the second pre-charger. The device also includes a separator having apertures such that PM in the second exiting air stream passes through the separator to agglomerate with PM in the first exiting air stream to form agglomerated particles. The apertures are sized such that the agglomerated particles are larger than the apertures to preclude the agglomerated particles from reentering the second exiting air stream.

Examples are disclosed that relate to cooking systems with internal ventilation systems. One example provides a cooking system comprising a ventilation duct comprising an inlet aperture configured to receive cooking exhaust, a fan disposed within the ventilation duct, the fan being configured to pull the cooking exhaust through the inlet aperture and the ventilation duct, and a particulate removal system positioned within the ventilation duct between the inlet aperture and the fan. In an example, the particulate removal system includes a cyclonic filtration system.

A DC power source operating portable human body carrying potential feedback electronic human breath filtration device is an electronic nose mask with directional ionic air filtration control and is the most ideal alternative to conventional filter paper type nose mask.

Aspects of a sound-reducing air purification unit. In some units, the sound-reducing air purification unit can include a filter, a blower that causes air to flow through the filter and into an inlet of the blower, a sound reduction unit between the filter and an outlet, to absorb sound emitted by the blower, a discharge channel that channels the air expelled from the blower to a discharge grille, sound-reducing media positioned on either side of the discharge channel, to absorb sound emitted by the blower within the discharge channel, and a discharge grille that allows the air to flow from the discharge channel into the outlet.

A system for removing dust from the air includes a dust-removing system inlet, a dust-removing system outlet and an electric field apparatus. The electric field apparatus has an electric field apparatus inlet, an electric field apparatus outlet, a dust-removing electric field cathode and a dust-removing electric field anode. The dust-removing electric field cathode and the dust-removing electric field anode are used to generate an ionizing electric field for dust removal. The system for removing dust from the air can effectively remove particulates in the air.

An exhaust dust removal system includes an electric field device (1021) and a cooling device. The electric field device (1021) has an electric field device inlet, an electric field device outlet, a dust removal electric field cathode (10212), and a dust removal electric field anode (10211).
