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.

A device comprises a delivery engine comprising a volatile composition and a microporous membrane, and an evaporation assistance element. In some embodiments the device includes a fan is configured to move a volume of air over the microporous membrane to facilitate evaporation of the volatile composition into the atmosphere.

A purification device for disinfecting and filtering intake air is disclosed. The purification device comprises a housing provided with a number of inlet perforations for allowing the intake air to enter the housing and a number of air outlet perforations for allowing air purified by the purification device to leave the housing. The purification device moreover comprises a fan arranged inside the housing to suck the intake air into the housing and blow the purified air out of the housing. The purification device further comprises an ultraviolet radiation lamp arranged inside the housing to irradiate the intake air. The purification device also comprises a high-efficiency particulate air (HEPA) filter arranged to filter the intake air before the intake air leaves the housing as purified air. The filter comprises a plurality of pleats arranged in such a manner that the angle between adjacent pleats is 30 degrees or less.

A deodorizer for insertion into athletic and other equipment, having an outer housing that is infused with an antimicrobial agent and that has ventilation holes, and containing a moisture absorbing deodorizer within the outer housing. The deodorizer absorbs moisture that allows bacteria to grow and the antimicrobial infused outer housing kills existing bacteria, thereby reducing bacteria and odor.

A face mask containing a network of conductive activated carbon meso-fibers crosslinked with a crosslinking agent bonded to a insulative polymeric micro-fiber based purification element. The purification element is captured between two ridged porous elements and contacted to the face by a biocompatible flexible polymeric seal. Optionally the front cover attaches to a main frame of the mask through a system of sliding locks that are coupled with bayonet latch mechanisms. The face mask attaches to the head of a wearer through a harness that couples with the sliding locks or alternatively with a biocompatible adhesive.

A chlorine dioxide gas generating agent pack includes a chlorine dioxide gas generating agent containing a mixture of chlorite powder, gas generation control agent powder, moisture-absorbent powder, water-absorbent resin powder, and activating agent powder; and a gas-permeable film container permeable to water vapor and chlorine dioxide gas and containing the chlorine dioxide gas generating agent. This chlorine dioxide gas generating agent pack is suitable for being carried to a region where sterilization, disinfection and deodorization are required.
