[0060] The primary filter is an air filter used to filter large particles in the air.

[0066] After entering the rectangular box 1, the air continues to flow after being treated by the pre-filter. It flows through a strong electric field and is subjected to a series of composite electro-purification effects. The strong electric field ionizes and oxidizes harmful gases, thereby generating harmless substances such as carbon dioxide and water. At the same time, the electrostatic field optimizes the air effect by electrostatic dust collection. The treated air flows through the circular tube 3024 and is released from the opening of the upper cover 3022. The air is purified and filtered.

[0067] Polarization and adsorption: When air passes through the space between coaxial electrodes, particulate matter in the air is adsorbed onto electrodes with opposite polarity, thus achieving the adsorption and filtration functions of particles.

[0068] Electrochemical action: The high-voltage electric field between the electrodes has a strong electrochemical effect, which can decompose and reduce complex compound molecules in the air to generate harmless substances such as carbon dioxide and water. This action can effectively remove benzene, aldehydes, alcohols, hydrocarbons and other substances from the air and remove odors.

[0069] The inactivation effect of interelectrode radiation: There is strong ionizing radiation between the high-voltage electrodes. When viruses and bacteria pass through, they are affected by this radiation and lose their activity.

[0070] This invention is connected to a building ventilation duct. Air is supplied to the duct unit's purification single-tube, where a high-voltage electric field generated by a high-voltage transformer ionizes and oxidizes harmful gases. Simultaneously, an electrostatic field collects dust to optimize air quality, achieving the most suitable air environment at the lowest cost. This invention provides a comprehensive and multi-faceted air optimization solution, going beyond simple filtration and ventilation. It avoids filter component failures or secondary pollution due to quality issues. This invention is suitable for air purification and disinfection in industrial and civil building ventilation systems such as government offices, schools, clean rooms, restaurants, airports, and train stations.

[0073] The polarity wire 2021 exits through the slot of the upper cover 3022. The cap 3025 is inserted into the slot and pressed down to secure the polarity wire 2021 to the upper cover. The cap 3025 keeps the polarity wire 2021 stable.

[0074] Pre-filters are used to filter large particles in the air. They are available in pre-filter, medium-efficiency filter, and high-efficiency filter types. Installing a pre-filter improves the purification effect of the equipment and extends its service life. Pre-filters are purchased externally.
