摘要： An electrostatic air filter connected to a high voltage source, including an air flow channel, an ion generator, at least one corona electrode and at least one cumulative electrode, the corona electrodes and the cumulative electrodes are configured so that corona discharges occur between the corona electrodes and the cumulative electrodes due to a first potential difference, causing ionization of contaminant particles present in the air flow channel. A separator of contaminant particles is disposed in the air flow channel and includes input and output electrodes that enable the flow of air therethrough in a direction away from the input electrode to the output electrode and further to the channel outlet. During operation, there is a first potential difference between the corona and input electrodes and a second potential difference between the input and output electrodes, so that the electric field strength in the space between the input and output electrodes is directed opposite to that in the space between the ion generator and the input electrode.

摘要： The present invention relates to a respirator without breathing resistance, which has an air inlet duct that passes through an inside and an outside of the respirator and that has asymmetrical electrodes and particle capturing plates formed on an inner surface of the air inlet duct; ozone removing element that removes ozone generated by micro-plasma; and high voltage dc-dc converter that provides high voltage to the asymmetrical electrodes. It employs asymmetrical electrodes and particle capturing plates to filter air without generating breathing resistance. When the respirator according to the present invention is used, safety of a wearer may be maintained in accordance with an environment and breathing may be smoothly performed even while introduction of pathogenic bacteria, viruses, fungi, spores, fine dust, or the like included in air may be effectively blocked. Accordingly, the respirator may be widely utilized to maintain the safety of the wearer in various environments.

摘要： A device for cleaning of indoor air comprising capacitor precipitators, each consisting of two electrode elements or two groups of electrode elements connected to the respective pole of a high voltage source, air transported fans, at least one corona electrode and at least one counter electrode. The corona electrode and the counter electrode are each connected to the respective pole of a high voltage source. The device includes two air flow ducts for the air to be cleaned, which air flow ducts are placed along an axial reference line (AA) at a distance (d) from each other in the direction of the axial reference line (AA). Each air flow duct is associated with a capacitor precipitator and an air moving fan. At least one corona electrode is provided in the space between the air flow ducts. At least one counter electrode is located adjacent to the air flow ducts circumference. The air flow direction through the one air flow duct is diametrically opposite the air flow direction through the second air flow duct, and the air to be cleaned is passed into the space between the air flow ducts.

摘要： We disclose a window blind that includes a capacitor within each slat. Each plate of the capacitor may be connected to one of two batteries. At least one switch may be placed between each capacitor plate and its adjoining battery. When one switch is open, another switch may be closed thereby sending current to only one plate at a time. The plate that receives the current is negatively charged and the remaining plate is positively charged. The switch that is open may be changed to reverse the charges of the plates. This charge reversal may be actuated through a series of pull cord gestures from a user. By creating an electrical charge on the plates, dust is pulled from the air according to the net charge of the dust particles. The window blind therefore functions as an air purifier as well as a traditional window blind.

摘要： An apparatus to purify fresh air contains at least three types of filters such as high efficient particle filter 5, chemical filter 6 and two stage electrostatic filters 2. The filters are secured to fresh air unit 1 that is secured to the wall 4 or window 11 of the building. Particularly, the present invention contains low noise fan 7 to reduce noises entering from outside. The particle filters and chemical filters are either in rolled form or in plate form with protrusions to have effective filtration. More particularly, the present invention relates to an apparatus for purifying freshly supplied air from outdoor environment and recirculates the indoor air by using new type easily installable and serviceable, filters that are environmentally friendly biodegradable filters.

摘要： A filter media and a pleated filter with a first layer of filtration media, a layer of support material and a second layer of filtration media on the opposite side of the support material as the first layer of filter media. All three layers are laminated together and pleated. The support material provides the required stiffness and rigidity for the pleating process. The physical characteristics of the upstream layer of filtration media are contemplated to be different than the characteristics of the downstream layer of filtration media.
