The air we breathe is the  main element that sustains the beginning and continuity of all life forms in our planet, which we are all dependent on in order to live. It is also responsible for water cycle, temperature maintenance, crop pollination, humidity balance, and other biological processes that promotes continuity of life. Throughout the development of technology since the beginning of human civilization, it has contributed largely in the development of modern techniques and applications in both electric and mechanic technology, and more importantly, in the composition of medical substances and modern chemicals in continuous scientific experiments and research.

However, in the modern world today, the quality of air we are experiencing are now contaminated and polluted, especially in highly urbanized places where there are constant pollutants present. This is a cumulative result of the many years of technological effects, with most pollution in the air coming from the harmful gas emissions of vehicles, Lint Screens, equipments, and industrial facilities that were created to support modernization. When the hazardous contaminants start to accumulate in air, it can bring about a range of air-borne respiratory problems, and even some cases of congenital defects, both of which can be challenging and costly to treat.

Although nearly all governments in every country today have passed laws to address the growing issues in air pollution management, with large organizations that advocate environmental health also jumping into action, eliminating air pollutants can prove to be nearly impossible with the continued manufacture and use of hazardous modern technology. On the positive side, there are now many manufacturers that took the initiative to devise products with minimal to no environmental impact in order to contribute in the reduction of hazardous pollutants that can pose serious health risks for humans.

Many establishments and homes today use the popular air purifying technology from modern appliances to improve Indoor Air Quality and reduce the presence of allergens, microorganisms, second-hand smoke, and other contaminants in the air that can cause health hazards. These purifying appliances are usually a solo unit or a smaller device that is made to attach on air conditioning or HVAC units, and may use one of the many air purification techniques such as using UV rays, photo plasma technology, irradiation, purifying filters, or electronic air cleaners.

Today, there are probably dozens to hundreds of newer models already for air sterilizer equipments that use different cleaning systems, which provides a wide array of selections for consumers. Most models also come with replaceable parts to keep the purification process continuously efficient, like lint filters, screen covers, absorbent pads for odors, air scent and deodorizer cartridges, and other helpful accessories that serve to take the place of old filters or parts that have reached its maximum use.
