How do UV-Light Air Purifiers Work

The presence of respiratory illness among the global population is on the increase. One of the main reasons for the increasing problem with respiratory illness is an expansion in airborne environmental pollution. Today, there are several models of air purifiers available in the market. Every different type of air purifier works differently and uses different techniques for cleaning the air. One of the most efficient air purifiers available in the market is an ultraviolet air purifier. In the past, ultraviolet light has been used to purify water, air, and surfaces.

Ultraviolet air purifiers can efficiently decrease contaminants in the air with the application of ultraviolet light. These air purifiers reduce pollutants in the environment using the process of photochemistry. This process converts molecules of both water and oxygen into hydroxyl, hydrogen peroxide and ozone.

The working of UV-C light air purifiers is quite simple. UV-C light air purifiers use UV lamps that can possibly adjust and inactivate the DNA of microorganisms. The material of the emitter also matters in this process; it could be phosphor or quartz glass. The UV light purifiers are more effective because they do not depend on the quantity of air that it can be absorbed into the machine and finally cleaned. The method of using UV light is more about actively killing germs and bacteria at a molecular level. This is only possible because of the amount of strength found in UV light. UV light has sufficient power to be able to break down microorganisms at a molecular level, killing germs, virus, and bacteria without having suck in air into the device.

Although UV light can possibly deactivate microbes, whether it can do so within a compact air purifier system is a different thing. These air purifiers are usually promoted to decrease dust mite and mould allergens. Besides, the effectiveness of UV light in cleaning the air depends on different factors. Take a look:

• The material of the bulb releasing such light
• The great amount of light required
• Whether the pollutants come into contact with the UV light
• Whether the light is controlled by the cooling influence of airflow
• How long the pollutant is opened to the light

• The main benefit of an ultraviolet air purifier is the certainty that the airborne pollutants in the environment are finished. Ultraviolet air purifier filters are adequate for killing mould, bacteria, fungi, viruses, dust mite excrement, pet and human hair, and other microorganisms.
• The most reliable ultraviolet air purifiers use ultraviolet lighting ranges from a 185 nm low-intensity wavelength to a 250 nm high-intensity wavelength. It is vital to choose an ultraviolet air purifier that uses both high and low-intensity wavelengths.

Because the ultraviolet light kills airborne contaminants and doesn't clean them out, proper care of the bulb is required to maintain its most powerful wattage capacity.
