Pencemaran udara diartikan dengan turunnya kualitas udara sehingga udara mengalami penurunan mutu dalam penggunaannya dan akhirnya tidak dapat dipergunakan lagi sebagai mana mestinya sesuai dengan fungsinya. Untuk mengetahui tingkat pencemaran udara diperlukan suatu alat sebagai pemantau kualitas udara. Perkembangan pesat dalam alat dan cara kerja air purifier dalam ruang lingkup yang meluas sehingga air purifier yang seharusnya bermanfaat bagi lingkungan namun dalam kenyataannya merusak lingkungan. Kebutuhan manusia yang besar dalam hal alat dan peralatan namun tidak mengetahui dasar dari alat air purifier yang dapat diterapkan dan dikembangkan dengan bahan dan cara yang sederhana.

Contamination of hazardous chemicals is currently considered one of the major environmental problems. The methods of purification of gaseous emissions depending on the physicochemical properties of pollutants, in particular dangerous chemical, their aggregate state, concentration in the gas environment are studied in this article. The effect of aerosol content such as dust and soot is analyzed as well as the efficiency of purification methods at different temperature intervals, methods of purification of multicomponent mixtures. The comparative characteristics of thermochemical, reagent, sorption and catalytic methods are given and the prospects of their application in filtering systems of stationary and mobile objects are evaluated. It has been proved that almost any organic compounds can be oxidized (mineralized) on the TiO2surface. In practice, any photocatalytic air purifier includes a porous TiO2 deposited carrier, which is irradiated with ultraviolet rays and through which air is purged. Photocatalysis is suitable for domestic use as it can occur at room temperature. For example, a thermocatalytic method of destroying harmful substances requires preheating the air to a temperature above 200 ° C. Photocatalysis destroys substances that penetrate even through activated carbon filters. Features of formation of oxide coatings by plasma-electrolytic oxidation of titanium alloys are considered. It is proposed to refine the design of collective defense systems on armored vehicles and stationary facilities with additional installation in the filter-absorber of the grid with the deposited layer of catalytic material, which will neutralize various types of dangerous chemicals due to photocatalytic air purification.
