Disclosed is a fine dust collecting device using a human body based electrostatic energy harvesting element. The fine dust collecting filter device includes an electrostatic energy harvesting element for collecting and generating current; a charging filter connected to the electrostatic energy harvesting element such that the charging filter is electrically charged to have a first polarity and thus electrically charges fine dust particles; a collecting filter connected to the electrostatic energy harvesting element such that the collecting filter is electrically charged to have a second polarity opposite to the first polarity; and a rectifier disposed between and connected to the electrostatic energy harvesting element, and the charging filter and the collecting filter.

A method for reducing dust removal electric field couplings includes the following steps: selecting a ratio between a dust collection area of a dust removal electric field anode and a discharge area of a dust removal electric field cathode to be 1.667:1-1680:1. A dust removal electric field anode and/or dust removal electric field cathode size is selected so that the number of electric field couplings is less than or equal to 3. The number of electric field couplings is reduced, electric field energy consumption is low, electric field coupling consumption for an aerosol, water mist, oil mist and loose smooth particulate matter is reduced, and electric field energy is saved.

An engine emission treatment system incudes at least one out of an air inlet dust removal system (101), a tail gas dust removal system (102), and a tail gas ozone purification system. The tail gas dust removal system (102) has an inlet of the tail gas dust removal system, an outlet of the tail gas dust removal system, and a tail gas electric field device (1021). The tail gas ozone purification system has a reaction field (202), used for mixing an ozone stream and a tail gas stream for reaction. The engine emission treatment system may effectively treat engine emissions, so as to make the engine emissions cleaner.

This new application collects data from indoor and outdoor environments and with that data compiles databases, analyzes that data and finds relationships between pollutants, microbes, matter and diseases in humans, plants and animals. This new application is called the Artificial Intelligence Doctor. The application utilizes artificial intelligence, machine learning and parallel conveyor belts with imbedded microscope slides for the identification and analysis of microbes and matter. The application identifies microbes and matter using static electricity applied to microscope slides imbedded in conveyor belts using light microscopes, electron microscopes, polarized light microscopes, x ray machines, artificial intelligence and machine learning algorithms. The easy transfer conveyor belt system utilizes migration of microbes and microbes from drones and robots for easier identification.

An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) system air filter for a building ventilation system. The HVAC system air filter comprises a supportive frame configured to orient the HVAC system air filter within the building ventilation system. A composite filter medium retained within the supportive frame comprises a cotton gauze portion and an electrostatic portion. The cotton gauze portion is configured for treatment with a filter oil composition to enhance airflow and filtration of air flowing through the composite filter medium. The electrostatic portion is configured to electrostatically attract and agglomerate airborne molecular contaminants and volatile organic compounds (VOCs) as small as 0.001 microns in diameter. In some embodiments, the composite filter medium comprises substances configured to release a fragrance into air passing through the composite filter medium.
