Abstract

A method for eliminating airborne microorganisms in an air duct comprises placing a device containing at least one light emitting diode (LED) in the air duct so that the air flow passes through the beam emitted by the LED.

Claims

1. A method for the destruction of airborne microorganisms, comprising:

installing in an air duct a device having an enclosure and at least one unidirectional light emitting diode (LED) disposed so as to emit light from the enclosure, so that light emitted by the LED is aimed to a flow of air in the air duct.

2. The method of claim 1, wherein the emitted light is ultra-violet.

3. The method of claim 1, wherein the source of light emitted is from an aluminum gallium arsenide crystal.

4. The method of claim 1, wherein the device has a rechargeable power source.

5. The method of claim 1, wherein the device is installed in a heating duct.

6. The method of claim 1, wherein the device is installed in an air-conditioning duct.

7. The method of claim 1, further comprising the step of placing a fan inside the air duct to force air past the beam emitted by the LED.
