A system and method for mitigating airborne contamination in a conditioned indoor environment utilizes one or more sensing modules configured to detect presence and/or concentration of particles and/or aerosols at different locations. A control module employs an artificial intelligence algorithm to selectively activate at least one mitigation module utilizing machine learning programmed rules and output signals from the sensing module(s). The mitigation module(s) are configured to take one or more actions to reduce presence and/or concentration of particles and/or aerosols in the conditioned indoor environment.

A purification device for exercise environment is provided and includes a main body, a purification unit, a gas guider and a gas detection module. The purification unit, the gas guider and the gas detection module are disposed in the main body to guide the gas outside the main body through the purification unit for filtering and purifying the gas, and discharge a purified gas. The gas detection module detects particle concentration of suspended particles contained in the purified gas. The gas guider is controlled to operate and export the gas at an airflow rate within 3 minutes. The particle concentration of the suspended particles contained in the purified gas, which is filtered by the purification unit, is reduced to and less than 0.75 μg/m.sup.3. Consequently, the purified gas is filtered, and an exerciser in an exercise environment can breathe with safety.

A gas purifying and processing method for exercise environment is provided and includes steps: (a) providing a purification device for exercise environment in an exercise environment, wherein the purification device for exercise environment includes a main body, a purification unit, a gas guider and a gas detection module; (b) detecting a particle concentration of the suspended particles contained in the purified gas in real time by the gas detection module; and (c) detecting, issuing an alarm and/or notification, and notifying an exerciser to stop exercising, and feeding back to the purification device to adjust an airflow rate of the gas guider by the gas detection module, wherein the gas guider discharge a gas at the airflow rate within 3 minutes to reduce the particle concentration of the suspended particles to less than 0.75 μg/m.sup.3, wherein the airflow rate is at least 800 ft.sup.3/min, and the main body maintains a breathing distance ranged from 60 cm to 200 cm.
