FloroFresh 424 6″ XXL Fan & Filter Kit with Germicidal UV

The FloroFresh 424 6″ XXL Fan & Filter Kit is a fresh take on grow room cleanliness, adding UVC filtration to the already powerful GrowBright Tall Boy Carbon Filter. What makes this carbon filter kit special is the addition of the FloroFresh 424! By putting a high-output germicidal UVC fixture inside a regular carbon filter, pathogens and room odor are controlled simultaneously. UVC light kills the vectors being pulled through the carbon filter by destroying their DNA. All UVC light is contained to the inside of your carbon filter, so there’s no need to worry about the health of adjacent plants.

What is UVC Light?

UVC, or Ultraviolet C, is a non-visible wavelength of short-wave light radiation, falling between 100-280nm on the light spectrum. It is used primarily for germicidal applications, where UVC light exposure effectively neutralizes viruses and other pathogens. While UVC emitted from the Sun is almost entirely blocked by Earth’s atmosphere, specialized lighting technology is able to reproduce the 100-280nm spectrum.

Biological Effect of UV Light
While UVB radiation is widely recognized for its harmful effects on human skin and links to skin cancer, each of the UV bands (UVA, UVB and UVC) create different risks for humans.

UVC radiation refers to wavelengths shorter than 280 nm. These wavelengths are entirely absorbed by our atmosphere and no natural UVC radiation reaches the surface of the earth. These wavelengths are available to us through artificial sources.

In instances of prolonged direct exposure to UVC light, temporary eye and skin damage has been exhibited, such as cornea injury (sometimes referred to as “welder’s eye”) although this generally heals after a couple of days. Therefore, safety recommendations with UVC LEDs include protecting skin (in particular open wounds) and, most importantly, the eyes from UVC radiation.

Personal Protective Equipment (PPE)

UV radiation is easily absorbed by clothing, plastic or glass. Once absorbed, UV radiation is no longer active. When working with open UV radiation during maintenance, service or other situations, personal protective equipment covering all exposed areas is recommended. When working around UVC devices, one should:

Use UV goggles and/or full-face shields.

Prescription glasses and normal safety glasses do not protect eyes from UV exposure, so ANSI Z87 rated eyeglasses with wrap around lens to protect the side exposure is recommended. Consult with ANSI Z87 manufacturers for proper UV exposure protection equipment.

Cover any exposed skin using lab coats, nitrile gloves or other lab attire.
