The present invention relates to a device wherein: ozone is generated through an ozone generation element and a controller therefor and supplied through an air circulation fan to form an air flow by a separate fan, and peroxide or a limonene solution (olefin) supplied in a cartridge form and then transpired is supplied thereto. The air flow of the supplied ozone and the air flow of the peroxide or limonene solution (olefin) are designed to have a flow channel to maintain a laminar flow state for a smooth supply of respective generated particles; a turbulence-inducing flow channel is separately prepared to easily make turbulence through convergence of the circulations of the two flows; and an air-mixed space for making turbulence is separately prepared, such that the ozone and the peroxide or the ozone and the limonene solution (olefin) cause a sufficient chemical reaction in the space, and here, OH (hydroxyl) radicals are generated, and the generated radicals or negative ions again make a laminar flow channel and are released far away through the laminar flow channel, and thus, through the application of the purification principle of a natural system, the indoor air or the bacteria floating in the air is sterilized and purified by the same principle as in the natural system.La présente invention concerne un dispositif dans lequel : de l'ozone est généré par un élément de génération d'ozone et un dispositif de commande associé et fourni au moyen d'un ventilateur de circulation d'air pour former un flux d'air par un ventilateur séparé, et du peroxyde ou une solution de limonène (oléfine) fournie sous la forme d'une cartouche et ensuite diffusée est fourni(e) à celui-ci. Le flux d'air contenant l'ozone fourni et le flux d'air contenant le peroxyde ou la solution de limonène (oléfine) sont conçus pour avoir un canal d'écoulement permettant de maintenir un état d'écoulement laminaire pour une alimentation continue de particules respectives générées ; un canal d'écoulemen
