Abstract
A portable air purifier for reducing pollutants in the passenger cabin of a vehicle to concentrations at least as low as the US-EPA National Ambient Air Quality Standards for: carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide, lead, and particulate matter; plus benzene to a European ambient air standard. The purifier includes an air inlet and air outlet in communication with the vehicle cabin, with air circulation provided by a DC electric motor/blower attachable to a vehicle power plug. The filter assembly includes a specified series of filter media packets and a HEPA filter. The machine's preferred location is in the center of a rear seat where it can serve as an armrest/console and be secured by a seat belt.
Claims38
An air purifier for the reduction of specific air pollutants within motor vehicle cabins and similar enclosed structures comprising:
- a portable housing having an air inlet in communication with the cabin of a vehicle and similar enclosed structures, a filter assembly in communication with the air inlet and air outlet and selected filter media to remove specific pollutants from air flowing through the filter assembly, an air outlet in communication with the cabin of a vehicle, a motorized fan operable to draw air into the air inlet, through the filter assembly and through the air outlet;
- the motorized fan operable from a readily accessible power source;
- the air purifier functionally independent of but also operable in conjunction with any heating, ventilation or air conditioning system in a motor vehicle and other similar apparatus;
- the housing removably attachable to at least one preselected surface within or on a motor vehicle or other enclosed structure;
- and
- the air purifier adapted to accept for purification only that air which is contained within said cabin or similar enclosed structure, to the exclusion of immediate connection to air entering said cabin or similar enclosed structure from areas external thereto.
A method of reducing specific pollutants from air within a motor vehicle cabin or similar enclosed structure, comprising the steps of:
- removably attaching an air purifier that is operable by power onto a surface within said cabin or similar enclosed structure;
- said air purifier including an air inlet and an air outlet, both of said air inlet and air outlet being in direct fluid connection with the interior of said motor vehicle cabin or similar enclosed structure while having no direct fluid connection to any HVAC or other ventilation system that enters into said motor vehicle cabin or similar enclosed structure from the exterior thereof;
- connecting to said air purifier a proximal end of a power line adapted to transmit DC power;
- and
- connecting a distal end of said power line to a source of power that is accessible from within said cabin or similar enclosed structure.
An air purifier for the reduction of specific pollutants from the cabin of a vehicle and similar enclosed structures, comprising:
- a housing including an air conduit extending through said housing, said housing having on at least part of the exterior thereof an upholstery cover or other cushioning substance;
- an air inlet in fluid connection with a first end of said air conduit;
- an air outlet hole in fluid connection with a second end of said air conduit;
- a multiplicity of filter locations disposed within said air conduit, at least one of said filter locations being adapted to receive a filter media packet within said air conduit;
- at least one filter media packet disposed within one of said multiplicity of filter locations and selected to capture at least one predetermined air pollutant from air passing through said air conduit;
- a blower in fluid connection with said air conduit and adapted to draw air into said air conduit through said air inlet and discharge air out of said air conduit through said air outlet hole;
- and
- a connector for connecting to a power source for operating said blower.
An air purifier operable to reduce concentration levels of specific pollutants in the passenger cabin of a vehicle and similar enclosed structures, to levels at least as low as the following US-EPA National Ambient Air Quality Standards for at least one of the following:
- Carbon Monoxide-20 parts per million, Ozone-80 parts per billion, Nitrogen Dioxide-250 parts per billion, Sulfur Dioxide-636 parts per billion, Lead-1.5 micrograms per cubic meter, Particulate Matter 10 micrometers and less in diameter-150 micrograms per cubic meter, Particulate Matter 2.5 micrometers and less in diameter-65 micrograms per cubic meter;
- and
- reducing Benzene to levels at least as low as an ambient air quality standard in Europe of 10 micrograms per cubic meter (or 3 parts per billion);
- the air purifier comprising:
- a housing including and air inlet, and air outlet, a filter assembly disposed between the inlet and the outlet, and a blower for drawing an air flow from the interior of the vehicle and similar enclosed structures into the air inlet, through the filter assembly and through the air outlet into the interior of the vehicle and similar enclosed structures.
