Uv Light In Hvac Effectiveness

The uvgi light operates within the uv c spectrum which is the effective wavelength spectrum for germicidal efficiency.

Uv light in hvac effectiveness.

When properly installed and maintained within an hvac system uv lights increase the quality of air in buildings. Shortwave radiation uv c is emitted from these systems and is most effective at killing mold bacteria and viruses. The lights used in hvac systems are uv c lights meaning they operate at the c frequency on the spectrum and is between 200 285 nanometers in size. There are a couple different set ups for the uv lights in the hvac system.

Uv lights are particularly effective in humid climates where evaporator coils can easily get wet. Also if your hvac system has damaged or leaky ducts the vacuum created in the ducts could draw in new contaminates from attics and crawl spaces limiting the uv light effectiveness. But only certain uv lights can be used in air purification. Uv lights are in the news because of the pandemic but the technology is over 100 years old.

Uv lights for your hvac will not alleviate your symptoms caused by allergens since dust as well as dead fungi will still be present. Ultraviolet lights specifically germicidal uvc. The ultraviolet germicidal light uvgi can help eliminate many types of bacteria and viruses. Experts believe that improvements to hvac units and the addition of uv lights at the office or at the home can help in the fight against covid 19.
