FAQs

Is UVGI safe to use? ›

As typical of newer technologies, the evidence for safety is less documented than for more established ones. The use of UV technology that is not specifically designed for indoor air disinfection is not recommended. In some cases, it might result in hazardous exposure of eyes and skin to ultraviolet radiation.

Ultraviolet germicidal irradiation, or UVGI, is the use of ultraviolet (UV) energy to kill viral, bacterial, and fungal organisms. UVGI fixtures produce UV-C energy, which has shorter wavelengths than more penetrating UV-A and UV-B rays and pose less risk to human health.

Germicidal ultraviolet (GUV) radiation, also known as UV germicidal irradiation (UVGI), is a method of air and surface disinfection that may be more effective and energy efficient to reduce airborne disease transmission than alternatives such as energy-intensive high-ventilation solutions.

It is used, for example, for disinfection in wastewater treatment plants, laboratories, air-conditioning systems and even pools and aquariums as well as in various stages of food and beverage industrial processes. UV-C is also used in medical and hospital settings to sterilise instruments, work surfaces and the air.

Steril-Aire UVC devices do not produce UVV or ozone.

The UV process is chemical-free and creates no byproducts. Because UV is simple, swift and safe, millions of homes and businesses now use ultraviolet technology to disinfect their water.

Research has found that hospital-grade and personal UV sanitizer may effectively and quickly disinfect surfaces. For example, UVC rays may eliminate nearly 99.9% of microbes on phones after one minute. 6 Still, some factors may affect the effectiveness of UV sanitizers.

UV ozone cleaning is a photo-sensitized oxidation process in which organic molecules in their excited state chemically react with ozone molecules, resulting in the cleaving of bonds and the dissociation of molecules from the surface.

UVC radiation is effective at eliminating the threat from bacteria, viruses, mold spores, dust mites, fungi, and harmful airborne microorganisms in UV air disinfection systems. UVC ozone lamps are designed to emit wavelengths closer to 185 nm, which are useful in many types of UV air treatment systems.

Which two structures are the least susceptible to UV damage? ›

Endospores and Protozoan cysts are less susceptible to UV damage.

Ultraviolet light inactivates microorganisms by forming pyrimidine dimers in RNA and DNA, which can interfere with transcription and replication (Goosen and Moolenaar, 2008; Cutler and Zimmerman, 2011).

Ultraviolet germicidal lamps can destroy bacteria, molds, yeast, and viruses. Ultraviolet energy cannot be detected by the human eye. A bluish light will be visible through the filter of your lamp.

The type of ultraviolet light that's able to effectively get rid of mold is UV-C, which is a very short wavelength of UV light. Because of how beneficial UV light can be at the right amounts, this light is commonly used for disinfection purposes, which can include treating ballast water with UV disinfection.

Short-wavelength UVC is the most damaging type of UV radiation. However, it is completely filtered by the atmosphere and does not reach the earth's surface.

Flexi Says: Yes, UV light can kill both harmful and beneficial bacteria in aquariums. It does not discriminate between the two. However, UV sterilizers are typically used in a way that only water passing through the device is affected, leaving beneficial bacteria on surfaces within the aquarium largely unharmed.

Sunlight has long been recognized as a disinfectant. The sunlight-mediated inactivation of microorganisms is relevant in many types of applications and to many aquatic environments.

Known side effects of overexposure to UV-C radiation include transient corneal and conjunctival irritation (photo-keratoconjunctivitis) and skin irritation (erythema), which disappear within a 24 – 48 hour period, not currently known to produce lasting biological damage.

Fluorescent, high intensity discharge (HID), and UV germicidal lamps are considered a hazardous waste and must be collected intact for proper disposal or recycling.
