Definitions
- This invention relates to an air cleaning unit, and more particularly to an air cleaning unit which can effectively remove pollutants from the air, is relatively compact, can be powered by a standard electrical socket and which can have other functions as well, such as light illumination and the dispensing of fixed amounts of fragrance into the air.
- Numerous patents have issued in which air cleaning units are taught and described. These teachings are documented in, for example, U.S. Pat. No. 4,376,642 issued March 15, 1983 to Biotech Electronics Ltd. ; U.S. Pat. No. 3,735,560 issued May 29, 1973 to D.C. ellman; U.S. Pat. No. 3,783,588 issued January 8, 1974 to M. Hundis; U.S. Pat. No. 3,861,894 issued January 21, 1975 to R.C. Marsh; U.S. Pat. No. 4,114,082 issued September 19, 1978 to J.H. Newell; U.S. Pat. No. 4,133,653 issued January 9, 1979 to C. . -2-
- No air cleaning unit taught by the prior art can accomplish all of the following tasks: collect particles, sterilize air, act on organic gases including carbon monoxide and remove poisonous gases from the air, in addition to providing light and dispensing fragrance.
- the air cleaning unit of this invention accomplishes all of these tasks effectively. This improvement is achieved by passing air to be purified through a new filtering means in the air cleaning unit which filtering means comprises a means for creating an electromagnetic field".
- the filtering means is adapted to collect particles, namely, dust, pollen, cigarette smoke and other submicron particulate contaminations, and to oxidize and ionize certain substances in the air namely, fumes and pollutants.
- a light source, contained in one embodiment of the unit which has a wide wavelength spectrum (i.e.
- the present invention is directed to providing an air cleaning unit which can effectively remove pollutants from the air, is relatively compact, is powered by a standard electrical socket, and which can have other functions as well, such as light illumination and the dispensing of fixed amounts of fragance into the air.
- the filter means comprising an electromagnetic field created by current flowing along a coiled wire and further comprising a new filter, in combination with a light source, create an environment in a housing, forming a semi-enclosed volume, which effectively filters and purifies air passing through the air cleaning unit by removing particulates and by oxidizing or breaking certain pollutants in the air to less harm pollutants.
- the air is moved across the filter means by a fan means contained within the body of the housing.

- Wire mesh 62 in filter 60 blocks particles. More particles are blocked when the wire mesh has a higher density.
- Wire mesh 62 can be any metal or metal oxide, but is ideally iron, zinc oxide or copper oxide.
- Sponge-like material 66 on top of filter 60 is designed to collect fine particles and to contain a color indicator means which tells the user when filter 60 needs to be replaced. The purification of air by filter 60 is enhanced by induced current in the wire mesh caused by the electromagnetic field creating means and also by heat emitted from the light source. .
- the induced current in wire mesh 62 improves the ability of activated carbon 64 to react with gases.
- certain UV radiation wavelengths emitted by light source 84 kill microorganisms.
- Heat in chamber 32 generated by light source 84 increases the efficiency of the UV wavelengths on microorgan- isms.
- UV wavelengths and heat catalyze oxidation and other chemical reactions in the air cleaning unit. For instance, the following reaction -10-
- the current flowing through coiled wire 82 causes an electromagnetic field around the coil.
- the electromagnetic field causes ionization of gases.
- the electromagnetic field causes current to be induced in wire mesh 62 of filter 60. That is, the current flowing through coiled wire 82, by induction, causes induced current to flow in wire mesh 62 of filter 60.
- Ionization caused in chamber 32 and at and around filter 60 have at least two major purposes: 1) ionization per se causes the breakdown of certain harmful pollutants and 2) ionization of gases increases the rate of oxidation.
- the efficiency of the air cleaning unit can be increased by increasing the frequency of the current (such as by chopping " AC voltage) . This is so because increased current causes an increase in the electromagnetic field, thereby increasing ionization of air.
- air purification occurs in two stages — at chamber 24 which contains * filter 60 and at chamber 32. The purified air is forced out of the housing through perforations 42.
- Figure 4 depicts one of many possible filters that can be used with the air cleaning unit, this filter being a preferred filter.

- the indicator means may be located in any location within the housing of the air cleaning unit or it can even be attached to the outside structure of the housing.
- Sponge-like material 66 has electrical isolated properties and is covered with casing 69 made of nonconductive isolated fibers.
- Figure 5 depicts another possible filter comprising a wire mesh 62 and activated carbon 64 contained therein, all encased in a screen net of metal fibers 68.
- filter 60 can consist of activated carbon 64 attached to acrylic fibers, said acrylic fibers being in a shape similar to wire mesh 62.
