Guides to Choose A Best UV Air Purifier for Home

How UV Air Purifier Works?

Air purifiers that are equipped with ultraviolet light are able to kill all airborne microorganisms, like mold, bacteria, viruses and more. The UV technology they utilize release UV lights which contain UV rays. As the polluted air passes through the air purifier, organic matter in the air is exposed to the UV radiation and is completely destroyed. This is different to how filter air purifiers work.31k+oqAlfTL

UV light Technology Vs. HEPA Technology

Filters can help air purifiers to capture airborne particles and allergens. And HEPA filters can also capture germs and microbes, but they are usually incapable of destroying or sterilizing microorganisms. This is what UV lights specialize in. If a space has a tendency to breed unhealthy microorganisms prolifically, air purifiers that have UV lights are the most powerful and effective ways to remove all them.

Considering the fact that air purifiers with UV light are not as effective as filters in removing dust, allergens and gaseous Volatile Organic Compounds (VOCs), UV lights are often used in conjunction with other filters (such as a HEPA filter or activated carbon filter) to build an enhanced air filtration system for air purifiers. But those using ozone generators to release UV lights can produce ozone gas, which may become harmful to humans.

There are two types of UV light available for air purifiers, one is Airstream disinfection, the other is Surface disinfection. Airstream disinfection requires a great quantity of UV rays and a powerful fan to accelerate the airflows, thus curbing the proliferation of microbes. While Surface disinfection is often installed in air-handling units to prevent bacteria proliferation.

Basically, a pre-filter and a charcoal filter remove larger particles and reduce common household odors caused by smoking, cooking or pets. And a True HEPA filter captures up to 99.97% of airborne particles as small as 0.3 microns (including dust mites, pollen, pet dander and other allergens). The benefits of most air purifiers may end there, but this unit is not average. It uses UV-C light technology to kill airborne bacteria, viruses and mold spores. And with the help of titanium dioxide, the UV-C light is able to decompose odor molecules. The GermGuardian air purifier with UV light works efficiently but quietly. Besides, this unit comes with a new feature that has an indicator lights to remind you when you should replace the filter and the UV-C bulb automatically.

1. Ideal for medium or large rooms
2. UV-C light combines the HEPA air filtration to eliminate both airborne particles and microbes, including dust mites, pet dander, pollen, bacteria, viruses and mold spores
3. Auto indicator lights alert you the right time to change the filter and the UV-C bulb
4. CADR rated 125+, 5-year warranty

Its 7 types of filtration contain six leading purification technologies, which work effectively to eliminate airborne toxins, allergens, particles, microscopic viruses and bacteria. The permanent pre-filter, as a forerunner of the entire purification system, providing previous and necessary filtration for other filters. The long-lasting HEPA filter is clinically proven up to 99.97% efficient at removing airborne particles and allergens while the activated carbon filter absorbs airborne chemicals, gases and common household odors. In addition to basic filter filtration, this unit has an electrostatic dust collector to trap particles and pollutants, an ozone-safe ionizer to enhance the filter efficiency, and the germicidal UV lamp to eliminate airborne microorganisms. As for the self-monitoring system, this unit features a wide array of sensors and monitors. Diagnostic sensors alert you to when you should replace the filters and clean the metal dust collector grid while sensors of odor, dust and allergen will show you what sort of airborne pollutants are detected. The clean air monitor lights display air quality levels, and the UV light and ionizer indicators will let you know whether they are working or not. When set on AUTO, it can help to maximize filtration performance and save energy. In addition to all of these features, this unit runs quietly and efficiently, making it very practical to use.
