## Abstract

A multichannel air purification device comprising a plurality of adjacent air channels in fluid communication with one another having a UV-C light source illuminate at least one air flow chamber, an air input means for allowing air into the channels, an air output means for allowing the air to exit the channels, openings between the channels for allowing air to pass from one channel to another channel, and a fan for drawing air through the device.

## Claims

### Claim 1

A multichannel air purification device comprising
a plurality of adjacent air channels in fluid communication with one another having a UV-C light source illuminate at least one air flow chamber,
an air input means for allowing air into the channels, an air output means for allowing the air to exit the channels, openings between said channels for allowing air to pass from one channel to another channel, and a fan for drawing air through the device;
communications controls for controlling an amount of UV-C light dosage administered by varying the speed of the fan as well as varying the intensity of UVC light sources wherein said communication controls are selected from wired communication and wireless communication;
a cloud storage based database;
a series of sensors that measure and record to the cloud storage based database air flow velocity and UVC intensity as sensed data,
a gateway configured to initiate a log of the sensed data, at a predetermined time interval by communicating said sensed data to a cellular antenna or wired connection through said communication controls,
wherein said communication controls is in communication with the cloud storage based database, for storing the sensed data, and
wherein said cloud storage based service is configured for storing and monitoring the sensed data thereby enabling real time tracking of device energy consumption, device performance, and device lifespan.

### Claim 2 (depends on 1)

The air purification device of claim 1 wherein said air channels have side walls and first and second ends, and said openings between said channels are located at the ends in opposite walls where channels are linked in series.

### Claim 3 (depends on 1)

The air purification device of claim 1 wherein said channels have side walls and symmetric ends, and said openings between said channels are located at both ends of said channels, in which said openings allow for air to travel simultaneously through a plurality of channels in a parallel fashion.

### Claim 4 (depends on 1)

The air purifier of claim 1, wherein said wireless communication is via a radio frequency controller and is selected from 2.4 GHz, 900 MHz, and cellular.

### Claim 5 (depends on 1)

The air purification device of claim 1 wherein said air flow is calculated from readings from a tachometer that measures RPMs of a fan, and wherein said UVC intensity measurement is selected from a direct UVC sensor, a voltage meter, an ammeter, and combinations thereof, and output data is presented in units for airflow as feet per second, and UVC intensity as microwatts per square centimeter.
