Claim:
1. A regenerative air purification system comprising: a gas adsorption filter having a reaction surface for photo-catalytic oxidation (PCO), wherein the gas adsorption filter can capture volatile organic compounds; a set of gas sensors configured to sense at least one kind of the volatile organic compounds on the adsorption filter surface; a processor configured to receive input data from the set of sensors, and to compare with predetermined upper threshold or lower threshold; wherein, when the input data exceeds a predetermined upper threshold or lower threshold indicating that a specified concentration of said at least one kind of the compounds is present on the adsorption filter, an alert signal is generated on the processor; a heater that can be turned on/off by the alert signal, and can heat up the gas adsorption filter to make the captured compounds to be easily desorbed from the gas adsorption filter; and UV lamps that can be turned on/off by the alert signal, and can convert the desorbed compounds near the reaction surface into H
