Do Uv Light Air Purifier Work

When an air purifier uses a uv light it promises to eliminate airborne pathogens.

Do uv light air purifier work.

Purifiers have a system that forces air through the device and as the air passes through the uv light it is disinfected before going back into the room. However this type of purification cleans as much air as your television. As a result the uv light of the air purifier acts together with other processes to clean the air. You ll also find uv ultraviolet light filters on the market which often claim to destroy biological impurities like mold or bacteria but many require higher wattage and greater exposure to be.

You might be familiar with the way hanging laundry out in the sunshine helps kill any germs or mold clinging to it. Many point to the uv light hospitals use to purify equipment. For decades scientists have learnt about the disinfection capability of ultraviolet wavelengths particularly germicidal uv additionally understood as uv c. They target a very specific type of air contaminant namely microorganisms such as bacteria viruses and mold spores.

Yes some uv air purifiers really work. According to the national academy of sciences it s probable that this is true because uv light has been used to disinfect surfaces and water for a long time and it s generally successful. Do uv light air purifier work. Ultraviolet uv lights for hvac systems are commonly known as ultraviolet germicidal irradiation uvgi systems.

Uv light air purifiers are generally a combination of a forced air system and another filter like a hepa filter. In recent years germicidal uv light assisted stop the spread of countless pathogens like the flu as well as other superbugs. Uv air purifiers are a single technology stand alone device used to clean the indoor air. Ambient in house air is forced through the unit and ventilated through a chamber with bulbs emitting light within the uv c frequency.

In theory ultraviolet rays will kill the microorganisms passing through your air filter. These air purifiers use powerful uv c lights to disrupt and destroy dna in bacteria rendering them unable to reproduce and therefore they die out. Through the sole power of ultraviolet light the air cleaner will kill off microorganisms like mold bacteria and viruses. Numerous health studies have shown that uv c light in a specific wavelength and duration very effectively inactivates viruses bacteria mold mildew and fungi by breaking down their dna or rna leaving them unable to perform vital functions or reproduce.
